The '''Second Industrial Revolution''', also known as the '''Technological Revolution''',<ref>{{cite web|last=Muntone|first=Stephanie|title=Second Industrial Revolution|url=http://www.education.com/study-help/article/us-history-glided-age-technological-revolution/|work=Education.com|publisher=The McGraw-Hill Companies|access-date=14 October 2013|url-status=dead|archive-url=https://web.archive.org/web/20131022224325/http://www.education.com/study-help/article/us-history-glided-age-technological-revolution/|archive-date=22 October 2013}}</ref> was a phase of rapid [[Discovery (observation)|scientific discovery]], [[standardisation]], [[mass production]] and [[industrialisation]] from the late 19th century into the early 20th century. The [[Industrial Revolution|First Industrial Revolution]], which ended in the middle of the 19th century, was punctuated by a slowdown in important inventions before the Second Industrial Revolution in 1870. Though a number of its events can be traced to earlier innovations in manufacturing, such as the establishment of a [[machine tool]] industry, the development of methods for manufacturing [[interchangeable parts]], as well as the invention of the [[Bessemer process]] and [[open hearth furnace]] to produce steel, later developments heralded the Second Industrial Revolution, which is generally dated between 1870 and 1914 (the beginning of [[World War I]]).<ref>[http://ushistoryscene.com/article/second-industrial-revolution/ The Second Industrial Revolution: 1870–1914]</ref>

Advancements in manufacturing and production technology enabled the widespread adoption of technological systems such as [[electrical telegraph|telegraph]] and railroad networks, [[Fuel gas|gas]] and [[water supply]], and [[sewage systems]], which had earlier been limited to a few select cities. The enormous expansion of rail and telegraph lines after 1870 allowed unprecedented movement of people and ideas, which culminated in a new wave of [[colonialism]] and [[globalization]]. In the same time period, new technological systems were introduced, most significantly [[electrical power]] and telephones. The Second Industrial Revolution continued into the 20th century with early factory [[electrification]] and the [[production line]]; it ended at the beginning of World War I.

Starting in 1947, the [[Information Age]] is sometimes also called the Third Industrial Revolution.

==Overview==
The Second Industrial Revolution was a period of rapid industrial development, primarily in the United Kingdom, Germany, and the United States, but also in France, the [[Low Countries]], Italy and Japan. It followed on from the [[First Industrial Revolution]] that began in Britain in the late 18th century that then spread throughout Western Europe. It came to an end with the start of the [[World War I]].  While the First Revolution was driven by limited use of [[steam engines]], [[interchangeable parts]] and [[mass production]], and was largely water-powered, especially in the United States, the Second was characterized by the build-out of railroads, large-scale iron and steel production, widespread use of [[machinery]] in manufacturing, greatly increased use of steam power, widespread use of the [[electrical telegraph|telegraph]], use of petroleum and the beginning of [[electrification]].  It also was the period during which modern organizational methods for operating large-scale businesses over vast areas came into use.<ref name="rv">{{Cite web |last=Richmond Vale Academy |date=2022-05-16 |title=Second Industrial Revolution: The Technological Revolution |url=https://richmondvale.org/en/blog/second-industrial-revolution-the-technological-revolution |access-date=2021-12-27 |website=richmondvale.org |language=en-GB}}</ref>

The concept was introduced by [[Patrick Geddes]], ''[[Patrick Geddes#Published works|Cities in Evolution]]'' (1910), and was being used by economists such as [[Erich Zimmermann]] (1951),<ref>[https://www.instituteforenergyresearch.org/history-electricity/ History of Electricity, Institute for Energy Research]</ref> but [[David Landes]]' use of the term in a 1966 essay and in ''[[The Unbound Prometheus]]'' (1972) standardized scholarly definitions of the term, which was most intensely promoted by [[Alfred D. Chandler, Jr.|Alfred Chandler]] (1918–2007). However, some continue to express reservations about its use. In 2003, Landes stressed the importance of new technologies, especially the [[internal combustion engine]], petroleum, new materials and substances, including alloys and [[Chemical industry|chemicals]], electricity and communication technologies, such as the [[telegraph]], telephone, and radio.<ref>James Hull, "The Second Industrial Revolution: The History of a Concept", ''Storia Della Storiografia,'' 1999, Issue 36, pp. 81–90</ref>

One author has called the period from 1867 to 1914, during which most of the great innovations were developed, "The Age of [[Synergy]]" since the inventions and innovations were engineering and [[Applied science|science-based]].<ref name="Smil2005">{{Cite book |last=Smil |first=Vaclav |url=https://archive.org/details/creatingtwentiet0000smil |title=Creating the Twentieth Century: Technical Innovations of 1867–1914 and Their Lasting Impact |publisher=Oxford University Press |year=2005 |isbn=0-19-516874-7 |location=Oxford; New York |author-link=Vaclav Smil |url-access=registration}}</ref>

== Industry and technology ==
A synergy between iron and steel, railroads and coal developed at the beginning of the Second Industrial Revolution.  Railroads allowed cheap transportation of materials and products, which in turn led to cheap rails to build more roads.  Railroads also benefited from cheap coal for their steam locomotives. This synergy led to the laying of 75,000 miles of track in the U.S. in the 1880s, the largest amount anywhere in world history.<ref>{{Harvnb|Chandler|1993|pp=171}}</ref>

=== Iron ===
The [[hot blast]] technique, in which the hot [[flue gas]] from a blast furnace is used to [[air preheater|preheat]] combustion air blown into a [[blast furnace]], was invented and patented by [[James Beaumont Neilson]] in 1828 at [[Wilsontown Ironworks]] in Scotland. Hot blast was the single most important advance in fuel efficiency of the blast furnace as it greatly reduced the fuel consumption for making pig iron, and was one of the most important technologies developed during the [[Industrial Revolution]].<ref>{{cite book |title=The Unbound Prometheus: Technological Change and Industrial Development in Western Europe from 1750 to the Present|last=Landes|first=David. S.|author-link=David Landes|year=1969|publisher=Press Syndicate of the University of Cambridge|location=Cambridge, New York|isbn=0-521-09418-6|page=92}}</ref> Falling costs for producing [[wrought iron]] coincided with the emergence of the railway in the 1830s.

The early technique of hot blast used iron for the regenerative heating medium.  Iron caused problems with expansion and contraction, which stressed the iron and caused failure. [[Edward Alfred Cowper]] developed the Cowper stove in 1857.<ref>{{Harvnb|Landes|1969|pp=256–7}}</ref> This stove used firebrick as a storage medium, solving the expansion and cracking problem.  The Cowper stove was also capable of producing high heat, which resulted in very high throughput of blast furnaces.  The Cowper stove is still used in today's blast furnaces.

With the greatly reduced cost of producing pig iron with [[coke (fuel)|coke]] using hot blast, demand grew dramatically and so did the size of blast furnaces.<ref>{{Harvnb|Landes|1969|p=218}}</ref><ref>{{cite book

=== Steel ===
[[File:ConverterB.jpg|thumb|A diagram of the [[Bessemer converter]]. Air blown through holes in the converter bottom creates a violent reaction in the molten pig iron that oxidizes the excess carbon, converting the pig iron to pure iron or steel, depending on the residual carbon.]]

The [[Bessemer process]], invented by [[Sir Henry Bessemer]], allowed the [[mass-production]] of steel, increasing the scale and speed of production of this vital material, and decreasing the labor requirements. The key principle was the removal of excess carbon and other impurities from [[pig iron]] by [[oxidation]] with air blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten.

The "acid" Bessemer process had a serious limitation in that it required relatively scarce [[hematite]] ore<ref>{{Harvnb|Landes|1969|p=228}}</ref> which is low in phosphorus. [[Sidney Gilchrist Thomas]] developed a more sophisticated process to eliminate the [[phosphorus]] from iron. Collaborating with his cousin, [[Percy Gilchrist]] a chemist at the [[Blaenavon Ironworks]], [[Wales]], he patented his process in 1878;<ref>{{Cite DWB|id=s-THOM-GIL-1850 |title=Thomas, Sidney Gilchrist}}</ref> [[Bolckow Vaughan]] & Co. in [[Yorkshire]] was the first company to use his patented process.<ref name=EB-Thom>{{cite EB1911 |wstitle=Thomas, Sidney Gilchrist |volume=26 |page=867}}</ref> His process was especially valuable on the continent of Europe, where the proportion of phosphoric iron was much greater than in England, and both in Belgium and in Germany the name of the inventor became more widely known than in his own country. In America, although non-phosphoric iron largely predominated, an immense interest was taken in the invention.<ref name=EB-Thom/>

[[File:Barrow Steelworks.jpg|thumb|The [[Barrow Hematite Steel Company]] operated 18 Bessemer converters and owned the largest steelworks in the world at the turn of the 20th century.]]

The next great advance in steel making was the [[Siemens–Martin process]]. Sir [[Charles William Siemens]] developed his regenerative furnace in the 1850s, for which he claimed in 1857 to able to recover enough heat to save 70–80% of the fuel. The furnace operated at a high temperature by using [[Air preheater|regenerative preheating]] of fuel and air for [[combustion]]. Through this method, an open-hearth furnace can reach temperatures high enough to melt steel, but Siemens did not initially use it in that manner.

French engineer [[Pierre-Émile Martin]] was the first to take out a license for the Siemens furnace and apply it to the production of steel in 1865. The Siemens–Martin process complemented rather than replaced the [[Bessemer process]].  Its main advantages were that it did not expose the steel to excessive nitrogen (which would cause the steel to become brittle), it was easier to control, and that it permitted the melting and refining of large amounts of scrap steel, lowering steel production costs and recycling an otherwise troublesome waste material. It became the leading steel making process by the early 20th century.

The availability of cheap steel allowed building larger bridges, railroads, skyscrapers, and ships.<ref>Alan Birch, ''Economic History of the British Iron and Steel Industry'' (2006)</ref> Other important steel products—also made using the open hearth process—were [[steel cable]], steel rod and sheet steel which enabled large, high-pressure boilers and high-tensile strength steel for machinery which enabled much more powerful engines, gears and axles than were previously possible. With large amounts of steel it became possible to build much more powerful guns and carriages, tanks, [[armored fighting vehicle]]s and naval ships.

=== Rail ===
[[File:The rail rolling mill, Hughesovka.jpg|thumb|A rail rolling mill in [[Donetsk]] in 1887]]
The increase in steel production from the 1860s meant that railways could finally be made from steel at a competitive cost. Being a much more durable material, steel steadily replaced iron as the standard for railway rail, and due to its greater strength, longer lengths of rails could now be rolled. [[Wrought iron]] was soft and contained flaws caused by included [[dross]]. Iron rails could also not support heavy locomotives and were damaged by [[hammer blow]]. The first to make durable [[rail profile|rails]] of steel rather than [[wrought iron]] was [[Robert Forester Mushet]] at the [[Darkhill Ironworks]], Gloucestershire in 1857.

The first of Mushet's steel rails was sent to [[Derby Midland railway station]]. The rails were laid at part of the station approach where the iron rails had to be renewed at least every six months, and occasionally every three. Six years later, in 1863, the rail seemed as perfect as ever, although some 700 trains had passed over it daily.<ref>{{cite book |last1=Rolt |first1=L.T.C |title=Victorian Engineering |year=1974 |publisher=Pelican |location=London |page=183 }}</ref> This provided the basis for the accelerated construction of railways throughout the world in the late nineteenth century.

The first commercially available steel rails in the US were manufactured in 1867 at the [[Cambria Iron Company|Cambria Iron Works]] in [[Johnstown, Pennsylvania]].<ref>{{cite book |title=Trains and Technology: Track and structures |last=Bianculli |first=Anthony J.|year=2003 |publisher=University of Delaware Press |location=Newark, DE |series=Volume 3 of ''Trains and Technology: The American Railroad in the Nineteenth Century'' |isbn=978-0-87413-802-3 |page=109 |url=https://books.google.com/books?id=7T3qECx0CLUC&q=steel%20rail%20railroad&pg=PA109}}</ref>

Steel rails lasted over ten times longer than did iron,<ref name="Fogel-1964">{{cite book |title=Railroads and American Economic Growth: Essays in Econometric History |last=Fogel |first=Robert W. |year=1964 |publisher=The Johns Hopkins Press |location=Baltimore |isbn=0801811481 |url=https://archive.org/details/railroadsamerica00foge }}</ref> and with the falling cost of steel, heavier weight rails were used. This allowed the use of more powerful locomotives, which could pull longer trains, and longer rail cars, all of which greatly increased the productivity of railroads.<ref>{{cite book |title=Inside the Black Box: Technology and Economics |last=Rosenberg |first=Nathan |year=1982 |publisher=Cambridge University Press |location=Cambridge |isbn=0-521-27367-6 |page=60 |url=https://archive.org/details/insideblackboxte00rose/page/60}}</ref> Rail became the dominant form of transport infrastructure throughout the industrialized world,<ref>{{Cite book |last1=Grubler |first1=Arnulf |title=The Rise and Fall of Infrastructures |year=1990 |url=http://www.iiasa.ac.at/Admin/PUB/Documents/XB-90-704.pdf |archive-url=https://web.archive.org/web/20120301221205/http://www.iiasa.ac.at/Admin/PUB/Documents/XB-90-704.pdf |archive-date=1 March 2012 |url-status=dead}}</ref> producing a steady decrease in the cost of shipping seen for the rest of the century.<ref name="Fogel-1964"/>

=== Electrification ===
{{Main|Electrification|Electricity}}
The theoretical and practical basis for the harnessing of electric power was laid by the scientist and experimentalist [[Michael Faraday]]. Through his research on the [[electromagnetic field|magnetic field]] around a [[Electrical conductor|conductor]] carrying a [[direct current]], Faraday established the basis for the concept of the electromagnetic field in physics.<ref name="EncBrit">{{cite EB1911 |wstitle=Faraday, Michael |volume=10 |page=173 |first=James Clerk |last=Maxwell |authorlink=James Clerk Maxwell}}</ref><ref name="IEEUK">[http://www.theiet.org/about/libarc/archives/biographies/faraday.cfm "Archives Biographies: Michael Faraday", The Institution of Engineering and Technology.] {{webarchive |url=https://web.archive.org/web/20110929004417/http://www.theiet.org/about/libarc/archives/biographies/faraday.cfm |date=29 September 2011 }}</ref> His [[invention]]s of [[electric motor|electromagnetic rotary devices]] were the foundation of the practical use of electricity in technology.

[[File:Light bulb Edison 2.jpg|thumb|U.S. Patent#223898: Electric-Lamp, issued 27 January 1880]]
In 1881, [[Sir Joseph Swan]], inventor of the first feasible [[incandescent light bulb]], supplied about 1,200 Swan incandescent lamps to the [[Savoy Theatre]] in the City of Westminster, London, which was the first theatre, and the first public building in the world, to be lit entirely by electricity.<ref>"The Savoy Theatre", ''[[The Times]]'', 3 October 1881</ref><ref name=TRE>[https://www.gsarchive.net/carte/savoy/electric.html Description of lightbulb experiment] in ''The Times'', 29 December 1881</ref> Swan's lightbulb had already been used in 1879 to light Mosley Street, in [[Newcastle upon Tyne]], the first electrical street lighting installation in the world.<ref>{{cite web|url=http://home.frognet.net/~ejcov/jwswan.html|title=Sir Joseph Wilson Swan|publisher=home.frognet.net|access-date=16 October 2010|url-status=dead|archive-url=https://web.archive.org/web/20110510005841/http://home.frognet.net/~ejcov/jwswan.html|archive-date=10 May 2011}}</ref><ref>{{cite web |url=http://www.rsc.org/Chemsoc/Activities/ChemicalLandmarks/UK/JosephSwan.asp |title=Sir Joseph Swan, The Literary & Philosophical Society of Newcastle |date=3 February 2009 |publisher=rsc.org |access-date=16 October 2010}}</ref> This set the stage for the electrification of industry and the home.

The first modern power station in the world was built by the English [[electrical engineer]] [[Sebastian de Ferranti]] at [[Deptford]]. Built on an unprecedented scale and pioneering the use of high voltage (10,000V) [[alternating current]], it generated 800 kilowatts and supplied central London. On its completion in 1891 it supplied high-voltage [[AC power]] that was then "stepped down" with transformers for consumer use on each street. [[Electrification]] allowed the final major developments in manufacturing methods of the Second Industrial Revolution, namely the [[assembly line]] and [[mass production]].<ref name ="Ford1922">{{Cite book|last1=Ford|first1=Henry|author1-link=Henry Ford|author2=Crowther, Samuel |title=My Life and Work: An Autobiography of Henry Ford|year=1922|url=http://www.gutenberg.org/catalog/world/readfile?fk_files=22786&pageno=45}}</ref>

The electric street railway became a major infrastructure before 1920.  The AC motor ([[Induction motor]]) was developed in the 1890s and soon began to be used in the [[electrification#History of electrification|electrification]] of industry.<ref>*{{cite book |title= Electrifying America: Social Meanings of a New Technology|last=Nye |first=David E.|year=1990 |publisher= The MIT Press |pages=14, 15 |location= Cambridge, MA; London}}</ref> Household electrification did not become common until the 1920s, and then only in cities.

=== Machine tools ===
{{Main|Machine tool}}
[[File:JFIScrewThread300.png|thumb|A graphic representation of formulas for the pitches of threads of screw bolts]]
The use of [[machine tool]]s began with the onset of the [[Industrial Revolution|First Industrial Revolution]]. The increase in [[mechanization]] required more metal parts, which were usually made of [[cast iron]] or [[wrought iron]]—and hand working lacked precision and was a slow and expensive process. One of the first machine tools was [[John Wilkinson (industrialist)|John Wilkinson]]'s boring machine, that bored a precise hole in [[James Watt]]'s first steam engine in 1774. Advances in the accuracy of machine tools can be traced to [[Henry Maudslay]] and refined by [[Joseph Whitworth]]. Standardization of screw threads began with [[Henry Maudslay]] around 1800, when the modern [[screw-cutting lathe]] made [[interchangeable parts|interchangeable]] V-thread machine screws a practical commodity.

In 1841, [[Joseph Whitworth]] created a design that, through its adoption by many British railway companies, became the world's first national machine tool standard called [[British Standard Whitworth]].<ref name="Roe1916pp9-10">{{Harvnb|Roe|1916}}, [https://archive.org/details/englishandameri01roegoog/page/n39 pp. 9–10.]</ref> During the 1840s through 1860s, this standard was often used in the United States and Canada as well, in addition to myriad intra- and inter-company standards.

The importance of [[machine tools]] to mass production is shown by the fact that production of the [[Ford Model T]] used 32,000 machine tools, most of which were powered by electricity.<ref name ="Hounshell1984">{{Hounshell1984}}</ref> [[Henry Ford]] is quoted as saying that mass production would not have been possible without electricity because it allowed placement of machine tools and other equipment in the order of the work flow.<ref>{{cite book |title= Edison as I Know Him |last=Ford |first=Henry |author2=Crowther, Samuel |year=1930 |publisher= Cosmopolitan Book Company |pages=30 |location= New York}}</ref>

=== Paper making ===
{{Main|Paper machine}}
The first paper making machine was the [[Fourdrinier machine]], built by Sealy and [[Henry Fourdrinier]], stationers in London. In 1800, [[Matthias Koops]], working in London, investigated the idea of using wood to make paper, and began his printing business a year later. However, his enterprise was unsuccessful due to the prohibitive cost at the time.<ref>Carruthers, George. Paper in the Making. Toronto: The Garden City Press Co-Operative, 1947.</ref><ref>Matthew, H.C.G. and Brian Harrison. "Koops. Matthias." ''Oxford Dictionary of National Biography: from the earliest times to the year 2000'', Vol. 32. London: Oxford University Press, 2004: 80.</ref><ref>Burger, Peter. Charles Fenerty and his Paper Invention. Toronto: Peter Burger, 2007. {{ISBN|978-0-9783318-1-8}}. pp. 30–32.</ref>

It was in the 1840s, that [[Charles Fenerty]] in Nova Scotia and [[Friedrich Gottlob Keller]] in Saxony both invented a successful machine which extracted the fibres from wood (as with rags) and from it, made paper. This started a new era for [[History of paper|paper making]],<ref>Burger, Peter. Charles Fenerty and his Paper Invention. Toronto: Peter Burger, 2007. {{ISBN|978-0-9783318-1-8}}</ref> and, together with the invention of the [[fountain pen]] and the mass-produced [[pencil]] of the same period, and in conjunction with the advent of the steam driven rotary [[printing press]], wood based paper caused a major transformation of the 19th century economy and society in industrialized countries. With the introduction of cheaper paper, schoolbooks, fiction, non-fiction, and newspapers became gradually available by 1900. Cheap wood based paper also allowed keeping personal diaries or writing letters and so, by 1850, the [[clerk (position)|clerk]], or writer, ceased to be a high-status job. By the 1880s chemical processes for paper manufacture were in use, becoming dominant by 1900.

=== Petroleum ===
The [[petroleum industry#History|petroleum industry]], both production and [[Petroleum refinery|refining]], began in 1848 with the first oil works in Scotland. The chemist [[James Young (Scottish chemist)|James Young]] set up a tiny business refining the crude oil in 1848. Young found that by slow distillation he could obtain a number of useful liquids from it, one of which he named "paraffine oil" because at low temperatures it congealed into a substance resembling paraffin wax.<ref name=russell>{{cite book | last = Russell | first = Loris S. | title = A Heritage of Light: Lamps and Lighting in the Early Canadian Home | publisher = University of Toronto Press | year = 2003 | isbn = 0-8020-3765-8}}</ref> In 1850 Young built the first truly commercial oil-works and oil refinery in the world at [[Bathgate]], using oil extracted from locally mined [[torbanite]], shale, and bituminous coal to manufacture [[naphtha]] and lubricating oils; paraffin for fuel use and solid paraffin were not sold till 1856.

[[Drilling rig#Cable tool drilling|Cable tool drilling]] was developed in ancient China and was used for drilling brine wells.  The salt domes also held natural gas, which some wells produced and which was used for evaporation of the brine.  Chinese well drilling technology was introduced to Europe in 1828.<ref>

Although there were many efforts in the mid-19th century to drill for oil, [[Edwin Drake]]'s 1859 well near Titusville, Pennsylvania, is considered the first "modern oil well".<ref>[https://books.google.com/books?id=vArc08DO9ykC&pg=PA13 M.

Kerosene lighting was much more efficient and less expensive than vegetable oils, tallow and whale oil.  Although town gas lighting was available in some cities, kerosene produced a brighter light until the invention of the [[gas mantle]]. Both were replaced by electricity for street lighting following the 1890s and for households during the 1920s. Gasoline was an unwanted byproduct of oil refining until automobiles were mass-produced after 1914, and gasoline shortages appeared during World War I. The invention of the [[Burton process]] for [[cracking (chemistry)|thermal cracking]] doubled the yield of gasoline, which helped alleviate the shortages.<ref name = Yergin/>

=== Chemical ===
[[File:BASF Werk Ludwigshafen 1881.JPG|thumb|The [[BASF]]-chemical factories in [[Ludwigshafen]], Germany, in 1881]]
[[Synthetic dye]] was discovered by English chemist [[William Henry Perkin]] in 1856. At the time, chemistry was still in a quite primitive state; it was still a difficult proposition to determine the arrangement of the elements in compounds and chemical industry was still in its infancy. Perkin's accidental discovery was that [[aniline]] could be partly transformed into a crude mixture which when extracted with alcohol produced a substance with an intense purple colour. He scaled up production of the new "[[mauveine]]", and commercialized it as the world's first synthetic dye.<ref name="chemistry.msu.edu">{{cite web |url=http://www.chemistry.msu.edu/Portraits/PortraitsHH_Detail.asp?HH_LName=Perkin |title=Sir William Henry Perkin |date=16 May 2003 |series=MSU Gallery of Chemists' Photo-Portraits and Mini-Biographies |publisher=Michigan State University, Department of Chemistry |location=East Lansing, MI |url-status=dead |archive-url=https://web.archive.org/web/20071030202902/http://www.chemistry.msu.edu/Portraits/PortraitsHH_Detail.asp?HH_LName=Perkin |archive-date=30 October 2007}}</ref>

After the discovery of mauveine, many new [[aniline dye]]s appeared (some discovered by Perkin himself), and factories producing them were constructed across Europe. Towards the end of the century, Perkin and other British companies found their research and development efforts increasingly eclipsed by the German chemical industry which became world dominant by 1914.

=== Maritime technology ===
[[File:HMS Devastation (1871).jpg|right|thumb|{{HMS|Devastation|1871|6}}, built in 1871, as it appeared in 1896]]
[[File:RMS Olympic's propellers.jpg|thumb|Propellers of the {{RMS|Olympic}} in 1911]]
This era saw the birth of the modern ship as disparate technological advances came together.

The [[propeller (marine)|screw propeller]] was introduced in 1835 by [[Francis Pettit Smith]] who discovered a new way of building propellers by accident. Up to that time, propellers were literally screws, of considerable length. But during the testing of a boat propelled by one, the screw snapped off, leaving a fragment shaped much like a modern boat propeller. The boat moved faster with the broken propeller.<ref>{{cite web |url=http://www.boatbuilding.com/article.php/designofpropellers1 |title=History and Design of Propellers: Part 1 |publisher=the boatbuilding.community |access-date=3 September 2007 |date=7 February 2004 |url-status=dead |archive-url=https://web.archive.org/web/20070811200813/http://www.boatbuilding.com/article.php/designofpropellers1 |archive-date=11 August 2007 }}</ref> The superiority of screw against paddles was taken up by navies. Trials with Smith's [[SS Archimedes|SS ''Archimedes'']], the first steam driven screw, led to the famous tug-of-war competition in 1845 between the screw-driven {{HMS|Rattler|1843|6}} and the paddle steamer {{HMS|Alecto|1839|6}}; the former pulling the latter backward at 2.5 knots (4.6&nbsp;km/h).

The first seagoing iron steamboat was built by [[Horseley Ironworks]] and named the ''[[Aaron Manby]]''. It also used an innovative oscillating engine for power. The boat was built at Tipton using temporary bolts, disassembled for transportation to London, and reassembled on the Thames in 1822, this time using permanent rivets.

Other technological developments followed, including the invention of the [[surface condenser]], which allowed boilers to run on purified water rather than salt water, eliminating the need to stop to clean them on long sea journeys. The ''[[SS Great Western|Great Western]]''<ref>Buchanan (2006), pp. 57–59</ref>
,<ref name="Beckett 2006, pp. 171–173">Beckett (2006), pp. 171–173</ref><ref>Dumpleton and Miller (2002), pp. 34–46</ref> built by engineer [[Isambard Kingdom Brunel]], was the longest ship in the world at {{convert|236|ft|m|abbr=on}} with a {{convert|250|ft|m|adj=on}} [[keel]] and was the first to prove that transatlantic steamship services were viable. The ship was constructed mainly from wood, but Brunel added bolts and iron diagonal reinforcements to maintain the keel's strength. In addition to its steam-powered [[paddle wheel]]s, the ship carried four masts for sails.

Brunel followed this up with the [[SS Great Britain|''Great Britain'']], launched in 1843 and considered the first modern ship built of metal rather than wood, powered by an engine rather than wind or oars, and driven by propeller rather than paddle wheel.<ref>Lienhard, John H (2003). ''The Engines of Our Ingenuity''. [[Oxford University Press]] (US). {{ISBN|978-0-19-516731-3}}.</ref> Brunel's vision and engineering innovations made the building of large-scale, propeller-driven, all-metal steamships a practical reality, but the prevailing economic and industrial conditions meant that it would be several decades before transoceanic steamship travel emerged as a viable industry.

Highly efficient [[Steam engine#Multiple expansion engines|multiple expansion steam engines]] began being used on ships, allowing them to carry less coal than freight.<ref name="Wells1890"/> [[Marine steam engine#Oscillating|The oscillating engine]] was first built by [[Aaron Manby (ironmaster)|Aaron Manby]] and Joseph Maudslay in the 1820s as a type of direct-acting engine that was designed to achieve further reductions in engine size and weight. Oscillating engines had the piston rods connected directly to the crankshaft, dispensing with the need for connecting rods. To achieve this aim, the engine cylinders were not immobile as in most engines, but secured in the middle by trunnions which allowed the cylinders themselves to pivot back and forth as the crankshaft rotated, hence the term ''oscillating''.

It was [[John Penn (engineer)|John Penn]], engineer for the [[Royal Navy]] who perfected the oscillating engine. One of his earliest engines was the [[grasshopper beam engine]]. In 1844 he replaced the engines of the [[British Admiralty|Admiralty]] yacht, {{HMS|Black Eagle}} with oscillating engines of double the power, without increasing either the weight or space occupied, an achievement which broke the naval supply dominance of [[Boulton & Watt]] and [[Henry Maudslay|Maudslay, Son & Field]]. Penn also introduced the [[marine steam engine#Trunk|trunk engine]] for driving screw propellers in vessels of war. {{HMS|Encounter|1846|6}} (1846) and {{HMS|Arrogant|1848|6}} (1848) were the first ships to be fitted with such engines and such was their efficacy that by the time of Penn's death in 1878, the engines had been fitted in 230 ships and were the first mass-produced, high-pressure and high-revolution marine engines.<ref>Osbon, G.

Longmans, London.</ref>

The revolution in naval design led to the first modern [[battleship]]s in the 1870s, evolved from the [[ironclad]] design of the 1860s. The [[Devastation-class ironclad|''Devastation''-class]] [[turret ship]]s were built for the British [[Royal Navy]] as the first class of ocean-going [[capital ship]] that did not carry [[sail]]s, and the first whose entire main armament was mounted on top of the hull rather than inside it.

===Rubber===
The [[vulcanization]] of rubber, by American [[Charles Goodyear]] and Englishman [[Thomas Hancock (inventor)|Thomas Hancock]] in the 1840s paved the way for a growing rubber industry, especially the manufacture of [[Tyres|rubber tyre]]s<ref>{{cite book|title=1493: Uncovering the New World Columbus Created|year=2011|publisher=Random House Digital, Inc.|url=https://books.google.com/books?id=Veu9u0brhrcC&pg=PA245 |pages=244–245|isbn=9780307265722}}</ref>

[[John Boyd Dunlop]] developed the first practical [[pneumatic]] tyre in 1887 in South Belfast. [[Willie Hume]] demonstrated the supremacy of Dunlop's newly invented pneumatic tyres in 1889, winning the tyre's first ever races in Ireland and then England.<ref name="Gold Hume">[http://www.thepedalclub.org/archives/goldenbook/u-z/WilliamHume.html The Golden Book of Cycling – William Hume, 1938.

===Bicycles===
The modern bicycle was designed by the English engineer [[Harry John Lawson]] in 1876, although it was [[John Kemp Starley]] who produced the first commercially successful safety bicycle a few years later.<ref>{{cite web|url=http://www.makingthemodernworld.org.uk/icons_of_invention/technology/1880-1939/IC.025/|title=Icons of Invention: Rover safety bicycle, 1885|publisher=The Science Museum.|access-date=5 June 2010}}</ref> Its popularity soon grew, causing the [[bike boom]] of the 1890s.

Road networks improved greatly in the period, using the [[Macadam]] method pioneered by Scottish engineer [[John Loudon McAdam]], and hard surfaced roads were built around the time of the bicycle craze of the 1890s. Modern [[Tarmacadam|tarmac]] was patented by British civil engineer [[Edgar Purnell Hooley]] in 1901.<ref name=Morton2002>{{citation |year=2002 |author=Ralph Morton|title=Construction UK: Introduction to the Industry| place=Oxford |publisher=Blackwell Science|page=51 |isbn=0-632-05852-8 |url=https://books.google.com/books?id=cW4CRawd1TgC&pg=PA51 |access-date=22 June 2010}}.</ref>

===Automobile===
[[File:1885Benz.jpg|thumb|Benz Patent-Motorwagen, first production automobile, first built in 1885]]
[[File:1910Ford-T.jpg|thumb|The 1910 Ford Model T]]
German inventor [[Karl Benz]] patented the world's [[Benz Patent Motorwagen|first automobile]] in 1886. It featured wire wheels (unlike carriages' wooden ones)<ref>[[G.N. Georgano]] ''Cars: Early and Vintage, 1886–1930''. (London: Grange-Universal, 1985)</ref> with a four-stroke engine of his own design between the rear wheels, with a very advanced coil ignition <ref name="Georgano">[[G.N. Georgano]]</ref> and evaporative cooling rather than a radiator.<ref name="Georgano"/> Power was transmitted by means of two [[roller chain]]s to the rear axle. It was the first [[automobile]] entirely designed as such to generate its own power, not simply a motorized-stage coach or horse carriage.

Benz began to sell the vehicle, advertising it as the Benz Patent Motorwagen, in the late summer of 1888, making it the first commercially available automobile in history.

[[Henry Ford]] built his first car in 1896 and worked as a pioneer in the industry, with others who would eventually form their own companies, until the founding of Ford Motor Company in 1903.<ref name="Ford1922" /> Ford and others at the company struggled with ways to scale up production in keeping with Henry Ford's vision of a car designed and manufactured on a scale so as to be affordable by the average worker.<ref name="Ford1922" /> The solution that Ford Motor developed was a completely redesigned factory with [[machine tools]] and special purpose machines that were systematically positioned in the work sequence. All unnecessary human motions were eliminated by placing all work and tools within easy reach, and where practical on conveyors, forming the [[assembly line]], the complete process being called [[mass production]]. This was the first time in history when a large, complex product consisting of 5000 parts had been produced on a scale of hundreds of thousands per year.<ref name ="Ford1922" /><ref name="Hounshell1984" /> The savings from [[mass production]] methods allowed the price of the [[Model T]] to decline from $780 in 1910 to $360 in 1916. In 1924 2 million T-Fords were produced and retailed $290 each.(${{format price|{{Inflation|US|290|1924}}}} in {{Inflation-year|US}} dollars{{Inflation-fn|US}})<ref>{{cite book |title=Mass Production, the Stock Market Crash and the Great Depression |last=Beaudreau |first=Bernard C. |year=1996 |publisher=Authors Choice Press|location=New York, Lincoln, Shanghi }}</ref>

===Applied science===
[[Applied science]] opened many opportunities. By the middle of the 19th century there was a scientific understanding of chemistry and a fundamental understanding of [[thermodynamics]] and by the last quarter of the century both of these sciences were near their present-day basic form. Thermodynamic principles were used in the development of [[physical chemistry]]. Understanding chemistry greatly aided the development of basic inorganic chemical manufacturing and the aniline dye industries.

The science of [[metallurgy]] was advanced through the work of [[Henry Clifton Sorby]] and others. Sorby pioneered [[metallography]], the study of metals under the [[microscope]], which paved the way for a scientific understanding of metal and the mass-production of steel. In 1863 he used etching with acid to study the microscopic structure of metals and was the first to understand that a small but precise quantity of carbon gave steel its strength.<ref>{{cite web|title=Biography of Henry Clifton Sorby|url=http://www.sorby.org.uk/hcsorby.shtml|access-date=22 May 2012|url-status=dead|archive-url=https://web.archive.org/web/20120205211758/http://www.sorby.org.uk/hcsorby.shtml|archive-date=5 February 2012}}</ref> This paved the way for [[Henry Bessemer]] and [[Robert Forester Mushet]] to develop the method for mass-producing steel.

Other processes were developed for purifying various elements such as [[chromium]], [[molybdenum]], [[titanium]], [[vanadium]] and [[nickel]] which could be used for making alloys with special properties, especially with steel. [[Vanadium steel]], for example, is strong and fatigue resistant, and was used in half the automotive steel.<ref>Steven Watts, ''The People's Tycoon: Henry Ford and the American Century'' (2006) p. 111</ref>  Alloy steels were used for ball bearings which were used in large scale bicycle production in the 1880s.  Ball and roller bearings also began being used in machinery.  Other important alloys are used in high temperatures, such as steam turbine blades, and stainless steels for corrosion resistance.

The work of [[Justus von Liebig]] and [[August Wilhelm von Hofmann]] laid the groundwork for modern industrial chemistry. Liebig is considered the "father of the fertilizer industry" for his discovery of [[nitrogen]] as an essential plant nutrient and went on to establish [[Liebig's Extract of Meat Company]] which produced the [[Oxo (food)|Oxo]] [[meat extract]]. Hofmann headed a school of practical chemistry in London, under the style of the [[Royal College of Chemistry]], introduced modern conventions for [[molecular modeling]] and taught Perkin who discovered the first synthetic dye.

The science of [[thermodynamics]] was developed into its modern form by [[Nicolas Léonard Sadi Carnot|Sadi Carnot]], [[William Rankine]], [[Rudolf Clausius]], [[William Thomson, 1st Baron Kelvin|William Thomson]], [[James Clerk Maxwell]], [[Ludwig Boltzmann]] and [[J. Willard Gibbs]]. These scientific principles were applied to a variety of industrial concerns, including improving the efficiency of boilers and [[steam turbine]]s. The work of [[Michael Faraday]] and others was pivotal in laying the foundations of the modern scientific understanding of electricity.

Scottish scientist [[James Clerk Maxwell]] was particularly influential—his discoveries ushered in the era of [[modern physics]].<ref>{{cite web |url=http://www-history.mcs.st-and.ac.uk/HistTopics/Knots_and_physics.html |title=Topology and Scottish mathematical physics |publisher=University of St Andrews |access-date=9 September 2013}}</ref> His most prominent achievement was to formulate a [[Maxwell's equations|set of equations]] that described electricity, [[magnetism]], and [[optics]] as manifestations of the same [[phenomenon]], namely the [[electromagnetic field]].<ref>{{cite web |title=James Clerk Maxwell |url=http://www.ieeeghn.org/wiki/index.php/James_Clerk_Maxwell |access-date=25 March 2013 |publisher=IEEE Global History Network}}</ref> The unification of light and electrical phenomena led to the prediction of the existence of [[radio waves]] and was the basis for the future development of radio technology by [[David Edward Hughes|Hughes]], [[Guglielmo Marconi|Marconi]] and others.<ref>{{cite journal |last=Maxwell |first=James Clerk |title=A dynamical theory of the electromagnetic field |url=http://upload.wikimedia.org/wikipedia/commons/1/19/A_Dynamical_Theory_of_the_Electromagnetic_Field.pdf |journal=Philosophical Transactions of the Royal Society of London |volume=155 |pages=459–512 |year=1865 |bibcode=1865RSPT..155..459M |doi=10.1098/rstl.1865.0008|s2cid=186207827 }}</ref>

Maxwell himself developed the first durable [[Color photography|colour photograph]] in 1861 and published the first scientific treatment of [[control theory]].<ref>{{cite journal |author=Maxwell, James Clerk |year=1868 |title=On Governors |journal=Proceedings of the Royal Society of London |volume=16 |pages=270–283 |doi=10.1098/rspl.1867.0055 |jstor=112510|doi-access= |s2cid=262724393 }}</ref><ref>{{cite journal |last=Mayr |first=Otto | author-link= Otto Mayr | title=Maxwell and the Origins of Cybernetics |journal=Isis |volume=62 |issue=4 |year=1971 |pages=424–444 |doi=10.1086/350788|s2cid=144250314 }}</ref> Control theory is the basis for [[process control]], which is widely used in [[automation]], particularly for [[process industries]], and for controlling ships and airplanes.<ref>{{cite book|title=A History of Control Engineering 1800–1930 |last=Benett|first= Stuart|year=1986|publisher =Institution of Engineering and Technology

These governors came into use in the late 18th century on wind and water mills to correctly position the gap between mill stones, and were adapted to steam engines by [[James Watt]].  Improved versions were used to stabilize automatic tracking mechanisms of telescopes and to control speed of ship propellers and rudders.  However, those governors were sluggish and oscillated about the [[Setpoint (control system)|set point]]. [[James Clerk Maxwell]] wrote a paper mathematically analyzing the actions of governors, which marked the beginning of the formal development of control theory.  The science was continually improved and evolved into an engineering discipline.

===Fertilizer===
[[Justus von Liebig]] was the first to understand the importance of [[ammonia]] as [[fertilizer]], and promoted the importance of inorganic minerals to [[plant nutrition]]. In England, he attempted to implement his theories commercially through a fertilizer created by treating [[phosphate of lime]] in bone meal with [[sulfuric acid]]. Another pioneer was [[John Bennet Lawes]] who began to experiment on the effects of various manures on plants growing in pots in 1837, leading to a manure formed by treating phosphates with sulphuric acid; this was to be the first product of the nascent artificial manure industry.<ref>{{cite EB1911 |wstitle=Lawes, Sir John Bennet |volume=16 |page=300}}</ref>

The discovery of [[Coprolite#Coprolite mining|coprolites]] in commercial quantities in [[East Anglia]], led Fisons and [[Edward Packard (businessman, born 1819)|Edward Packard]] to develop one of the first large-scale commercial fertilizer plants at [[Bramford]], and [[Snape, Suffolk|Snape]] in the 1850s. By the 1870s [[superphosphate]]s produced in those factories, were being shipped around the world from the port at [[Ipswich]].<ref>[http://www.yara.com/en/about/history/stories/fisons_inter.html History of Fisons at Yara.com] {{webarchive|url=https://web.archive.org/web/20060520151251/http://www.yara.com/en/about/history/stories/fisons_inter.html |date=20 May 2006 }}</ref><ref>{{Cite web|url=http://www.oxforddnb.com/templates/article.jsp?articleid=50172&back=|title=Oxford DNB}}</ref>

The [[Birkeland–Eyde process]] was developed by Norwegian industrialist and scientist [[Kristian Birkeland]] along with his business partner [[Sam Eyde]] in 1903,<ref>{{cite book|title=The development of modern chemistry|author=Aaron John Ihde|publisher=Courier Dover Publications|year=1984|isbn=0486642356|page=678}}</ref> but was soon replaced by the much more efficient [[Haber process]],<ref>{{cite book|title=A short history of twentieth-century technology c. 1900-c. 1950|author1=Trevor Illtyd Williams|author2=Thomas Kingston Derry|publisher=Oxford University Press|year=1982|isbn=0198581599|pages=134–135}}</ref>
developed by the [[Nobel prize]]-winning chemists [[Carl Bosch]] of [[IG Farben]] and [[Fritz Haber]] in Germany.<ref>[http://www.idsia.ch/~juergen/haberbosch.html Haber & Bosch ''Most influential persons of the 20th century''], by [[Jürgen Schmidhuber]]</ref> The process used molecular nitrogen (N<sub>2</sub>) and methane (CH<sub>4</sub>) gas in an economically sustainable synthesis of [[ammonia]] (NH<sub>3</sub>). The ammonia produced in the Haber process is the main raw material for production of [[nitric acid]].

===Engines and turbines===
The [[steam turbine]] was developed by Sir [[Charles Algernon Parsons|Charles Parsons]] in 1884. His first model was connected to a [[dynamo]] that generated 7.5&nbsp;kW (10&nbsp;hp) of electricity.<ref name="birrcastle.com">[http://www.birrcastle.com/steamTurbineAndElectricity.asp] {{webarchive|url=https://web.archive.org/web/20080510152751/http://www.birrcastle.com/steamTurbineAndElectricity.asp|date=10 May 2008}}</ref> The invention of Parson's steam turbine made cheap and plentiful electricity possible and revolutionized [[Turbinia|marine transport and naval warfare]].<ref>[http://www.universityscience.ie/pages/scientists/sci_charles_parsons.php] {{webarchive|url=https://web.archive.org/web/20080110063209/http://www.universityscience.ie/pages/scientists/sci_charles_parsons.php|date=10 January 2008}}</ref> By the time of Parson's death, his turbine had been adopted for all major world power stations.<ref>{{cite web

}}</ref> Unlike earlier steam engines, the turbine produced rotary power rather than reciprocating power which required a crank and heavy flywheel. The large number of stages of the turbine allowed for high efficiency and reduced size by 90%. The turbine's first application was in shipping followed by electric generation in 1903.

The first widely used [[internal combustion engine]] was the [[Otto engine|Otto type]] of 1876. From the 1880s until electrification it was successful in small shops because small steam engines were inefficient and required too much operator attention.<ref name="Smil2005" /> The Otto engine soon began being used to power automobiles, and remains as today's common gasoline engine.

The [[diesel engine]] was independently designed by [[Rudolf Diesel]] and [[Herbert Akroyd Stuart]] in the 1890s using thermodynamic principles with the specific intention of being highly efficient. It took several years to perfect and become popular, but found application in shipping before powering locomotives. It remains the world's most efficient prime mover.<ref name="Smil2005" />

===Telecommunications===
[[File:1891 Telegraph Lines.jpg|thumb|Major telegraph lines in 1891]]
The first commercial [[telegraph]] system was installed by Sir [[William Fothergill Cooke]] and [[Charles Wheatstone]] in May 1837 between [[Euston railway station]] and [[Camden Town]] in London.<ref>[http://www.connected-earth.com/journeys/Firstgenerationtechnologies/Thetelegraph/Thetelegraphicagedawns/index.htm The telegraphic age dawns]  {{webarchive|url=https://web.archive.org/web/20130219081333/http://www.connected-earth.com/journeys/Firstgenerationtechnologies/Thetelegraph/Thetelegraphicagedawns/index.htm |date=19 February 2013 }} BT Group Connected Earth Online Museum.

The rapid expansion of telegraph networks took place throughout the century, with the first [[undersea telegraph cable]] being built by [[John Watkins Brett]] between France and England.
The [[Atlantic Telegraph Company]] was formed in London in 1856 to undertake construction of a commercial telegraph cable across the Atlantic Ocean. This was successfully completed on 18 July 1866 by the ship [[SS Great Eastern|SS ''Great Eastern'']], captained by [[Sir James Anderson]] after many mishaps along the away.<ref>Wilson, Arthur (1994).

The telephone was patented in 1876 by [[Alexander Graham Bell]], and like the early telegraph, it was used mainly to speed business transactions.<ref>Richard John, ''Network Nation: Inventing American Telecommunications''  (2010)</ref>

As mentioned above, one of the most important scientific advancements in all of history was the unification of light, electricity and magnetism through [[Maxwell's equations|Maxwell's electromagnetic theory]]. A scientific understanding of electricity was necessary for the development of efficient electric generators, motors and transformers. [[David Edward Hughes]] and [[Heinrich Hertz]] both demonstrated and confirmed the phenomenon of electromagnetic waves that had been predicted by Maxwell.<ref name="Smil2005" />

The key development of the [[vacuum tube]] by Sir [[John Ambrose Fleming]] in 1904 underpinned the development of modern electronics and radio broadcasting. [[Lee De Forest]]'s subsequent invention of the [[triode]] allowed the amplification of electronic signals, which paved the way for radio broadcasting in the 1920s.

===Modern business management===
Railroads are credited with creating the modern [[business enterprise]] by scholars such as Alfred Chandler.  Previously, the management of most businesses had consisted of individual owners or groups of partners, some of whom often had little daily hands-on operations involvement.  Centralized expertise in the home office was not enough.  A railroad required expertise available across the whole length of its trackage, to deal with daily crises, breakdowns and bad weather.    A collision in Massachusetts in 1841 led to a call for safety reform.  This led to the reorganization of railroads into different departments with clear lines of management authority.  When the telegraph became available, companies built telegraph lines along the railroads to keep track of trains.<ref>

Railroads involved complex operations and employed extremely large amounts of capital and ran a more complicated business compared to anything previous.  Consequently, they needed better ways to track costs.  For example, to calculate rates they needed to know the cost of a ton-mile of freight.  They also needed to keep track of cars, which could go missing for months at a time.  This led to what was called "railroad accounting", which was later adopted by steel and other industries, and eventually became modern accounting.<ref>Compare: {{cite book |last= Chandler |first= Alfred Jr. |date= 1993 |title= The Visible Hand|publisher= Harvard University Press|page= 115 |isbn= 0674417682 | url = https://books.google.com/books?id=lAI3AwAAQBAJ | access-date = 29 June 2017 | quote = [...] American railroad accounting overstated operating costs and understated capital consumption.[...] The basic innovations in financial and capital accounting appeared in the 1850s in response to specific needs and were perfected in the years after the Civil War.

Later in the Second Industrial Revolution, [[Frederick Winslow Taylor]] and others in America developed the concept of [[scientific management]] or [[Taylorism]]. Scientific management initially concentrated on reducing the steps taken in performing work (such as bricklaying or shoveling) by using analysis such as [[time and motion study|time-and-motion studies]], but the concepts evolved into fields such as [[industrial engineering]], [[manufacturing engineering]], and [[business management]] that helped to completely restructure{{citation needed|date=June 2017}} the operations of factories, and later entire segments of the economy.

Taylor's core principles included:{{citation needed|date=June 2017}}

* replacing rule-of-thumb work methods with methods based on a scientific study of the tasks
* scientifically selecting, training, and developing each employee rather than passively leaving them to train themselves
* providing "detailed instruction and supervision of each worker in the performance of that worker's discrete task"
* dividing work nearly equally between managers and workers, such that the managers apply scientific-management principles to planning the work and the workers actually perform the tasks

==Socio-economic impacts==
[[File:Gdp-maddison-project-database.png|thumb|The [[Gross domestic product|GDP]] of the European powers experienced a significant growth during the Second Industrial Revolution.<ref>{{Cite web |title=Gross domestic product (GDP) |url=https://ourworldindata.org/grapher/gdp-maddison-project-database?tab=chart&time=1820..1913&facet=entity&uniformYAxis=0&country=DEU~GBR~FRA~AUT |access-date=2024-08-07 |website=Our World in Data}}</ref>]]
The period from 1870 to 1890 saw the greatest increase in economic growth in such a short period as ever in previous history. Living standards improved significantly in the newly industrialized countries as the prices of goods fell dramatically due to the increases in [[Productivity improving technologies (historical)|productivity]].  This caused unemployment and great upheavals in commerce and industry, with many laborers being displaced by machines and many factories, ships and other forms of fixed capital becoming obsolete in a very short time span.<ref name="Wells1890"/>

Crop failures no longer resulted in starvation in areas connected to large markets through transport infrastructure.<ref name="Wells1890"/>

Massive improvements in public health and sanitation resulted from [[public health]] initiatives, such as the construction of the [[London sewerage system]] in the 1860s and the passage of laws that regulated filtered water supplies—(the [[Metropolis Water Act 1852|Metropolis Water Act]] introduced regulation of the water supply companies in London, including minimum standards of water quality for the first time in 1852). This greatly reduced the infection and death rates from many diseases.

By 1870 the work done by steam engines exceeded that done by animal and human power.  Horses and mules remained important in agriculture until the development of the internal combustion tractor near the end of the Second Industrial Revolution.<ref>{{Cite journal|last1=Ayres|last2=Warr|first1=Robert U.|first2=Benjamin S. |title=Accounting for Growth: The Role of Physical Work |journal=Structural Change and Economic Dynamics |year=2005 |volume=16 |issue=2 |pages=181–209 |doi=10.1016/j.strueco.2003.10.003 |url=http://www.iea.org/work/2004/eewp/Ayres-paper1.pdf|access-date=11 January 2019|archive-url=https://web.archive.org/web/20101011153550/http://www.iea.org/work/2004/eewp/ayres-paper1.pdf|archive-date=11 October 2010|url-status=dead}}</ref>

Improvements in steam efficiency, like [[triple-expansion steam engine]]s, allowed ships to carry much more freight than coal, resulting in greatly increased volumes of international trade.  Higher steam engine efficiency caused the number of steam engines to increase several fold, leading to an increase in coal usage, the phenomenon being called the [[Jevons paradox]].<ref>{{cite book

By 1890 there was an international telegraph network allowing orders to be placed by merchants in England or the US to suppliers in India and China for goods to be transported in efficient new steamships.  This, plus the opening of the [[Suez Canal]], led to the decline of the great warehousing districts in London and elsewhere, and the elimination of many middlemen.<ref name="Wells1890"/>

The tremendous growth in productivity, transportation networks, industrial production and agricultural output lowered the prices of almost all goods.  This led to many business failures and periods that were called ''depressions'' that occurred as the world economy actually grew.<ref name="Wells1890"/>  See also: [[Long depression]]

The factory system centralized production in separate buildings funded and directed by specialists (as opposed to work at home). The division of labor made both unskilled and skilled labor more productive, and led to a rapid growth of population in industrial centers. The shift away from agriculture toward industry had occurred in Britain by the 1730s, when the percentage of the working population engaged in agriculture fell below 50%, a development that would only happen elsewhere (the [[Low Countries]]) in the 1830s and '40s. By 1890, the figure had fallen to under 10% and the vast majority of the British population was urbanized. This milestone was reached by the [[Low Countries]] and the US in the 1950s.<ref>{{cite journal|author=David Grigg|title=Agriculture in the World Economy: an Historical Geography of Decline|journal=Geography|year=1992|volume=77|issue=3|pages=210–222|jstor=40572192}}</ref>

Like the first industrial revolution, the second supported population growth and saw most governments protect their national economies with tariffs. Britain retained its belief in [[free trade]] throughout this period.  The wide-ranging social impact of both revolutions included the remaking of the working class as new technologies appeared. The changes resulted in the creation of a larger, increasingly professional, middle class, the decline of child labor and the dramatic growth of a consumer-based, material culture.<ref>Hull (1996)</ref>

By 1900, the leaders in industrial production was Britain with 24% of the world total, followed by the US (19%), Germany (13%), Russia (9%) and France (7%). Europe together accounted for 62%.<ref>Paul Kennedy, ''The Rise and Fall of the Great Powers'' (1987) p. 149, based on Paul Bairoch, "International Industrialization Levels from 1750 to 1980," ''Journal of European Economic History'' (1982) v. 11</ref>

The great inventions and innovations of the Second Industrial Revolution are part of our modern life.  They continued to be drivers of the economy until after WWII.  Major innovations occurred in the post-war era, some of which are: computers, semiconductors, the fiber optic network and the Internet, cellular telephones, [[combustion turbine]]s (jet engines) and the [[Green Revolution]].<ref>{{cite book|title=A Century of Innovation: Twenty Engineering Achievements That Transformed Our Lives|last=Constable|first=George|author2=Somerville, Bob|year=2003|publisher=Joseph Henry Press|location=Washington, DC|isbn=0-309-08908-5|url=http://www.greatachievements.org/id=2988}}{{Dead link|date=July 2018 |bot=InternetArchiveBot |fix-attempted=yes }}This link is to entire on line book.</ref> Although commercial aviation existed before WWII, it became a major industry after the war.

New products and services were introduced which greatly increased international trade. Improvements in [[steam engine]] design and the wide availability of cheap steel meant that slow, sailing ships were replaced with faster steamship, which could handle more trade with smaller crews. The [[history of chemical engineering|chemical]] industries also moved to the forefront. Britain invested less in technological research than the U.S. and Germany, which caught up.

The development of more intricate and efficient machines along with [[mass production]] techniques after 1910 greatly expanded output and lowered production costs. As a result, production often exceeded domestic demand. Among the new conditions, more markedly evident in Britain, the forerunner of Europe's industrial states, were the long-term effects of the severe [[Long Depression]] of 1873–1896, which had followed fifteen years of great economic instability. Businesses in practically every industry suffered from lengthy periods of low – and falling – profit rates and price deflation after 1873.

==United States==
The U.S. had its highest economic growth rate in the last two decades of the Second Industrial Revolution;<ref>{{Cite journal| last1 = Vatter | last2 = Walker| last3 =Alperovitz| first1 = Harold G.| first2 = John F.| first3 =Gar| title = The onset and persistence of secular stagnation in the U.S. economy: 1910–1990 |journal=Journal of Economic Issues |volume=29 |number=2 |pages=591–600 |jstor=4226974 |date = June 1995| doi = 10.1080/00213624.1995.11505696| url = https://dx.doi.org/10.1080/00213624.1995.11505696}}</ref> however, population growth slowed while productivity growth peaked around the mid 20th century.  The [[Gilded Age]] in America was based on heavy industry such as factories, railroads and coal mining.  The iconic event was the opening of the [[First transcontinental railroad]] in 1869, providing six-day service between the East Coast and San Francisco.<ref>Stephen E. Ambrose, ''Nothing Like It in the World; The men who built the Transcontinental Railroad 1863–1869'' (2000)</ref>

During the Gilded Age, American railroad mileage tripled between 1860 and 1880, and tripled again by 1920, opening new areas to commercial farming, creating a truly national marketplace and inspiring a boom in coal mining and steel production. The voracious appetite for capital of the great trunk railroads facilitated the consolidation of the nation's financial market in [[Wall Street]]. By 1900, the process of economic concentration had extended into most branches of industry—a few large corporations, some organized as "trusts" (e.g. Standard Oil), dominated in steel, oil, sugar, meatpacking, and the manufacture of agriculture machinery. Other major components of this infrastructure were the new methods for manufacturing steel, especially the [[Bessemer process]]. The first billion-dollar corporation was [[United States Steel]], formed by financier [[J. P. Morgan]] in 1901, who purchased and consolidated steel firms built by [[Andrew Carnegie]] and others.<ref name="Edward C. Kirkland 1961">Edward C. Kirkland, ''Industry Comes of Age, Business, Labor, and Public Policy 1860–1897'' (1961)</ref>

Increased mechanization of industry and improvements to worker efficiency, increased the productivity of factories while undercutting the need for skilled labor. Mechanical innovations such as batch and continuous processing began to become much more prominent in factories. This mechanization made some factories an assemblage of unskilled laborers performing simple and repetitive tasks under the direction of skilled foremen and engineers. In some cases, the advancement of such mechanization substituted for low-skilled workers altogether. Both the number of unskilled and skilled workers increased, as their wage rates grew<ref>Daniel Hovey Calhoun, ''The American Civil Engineer: Origins and Conflicts'' (1960)</ref> Engineering colleges were established to feed the enormous demand for expertise. Together with rapid growth of small business, a new middle class was rapidly growing, especially in northern cities.<ref>Walter Licht, ''Working for the Railroad: The Organization of Work in the Nineteenth Century'' (1983)</ref>

==Germany==
The [[German Empire]] came to rival Britain as Europe's primary industrial nation during this period. Since Germany industrialized later, it was able to model its factories after those of Britain, thus making more efficient use of its capital and avoiding legacy methods in its leap to the envelope of technology. Germany invested more heavily than the British in research, especially in chemistry, motors and electricity. The German [[Concern (business)|concern]] system (known as ''Konzerne''), being significantly concentrated, was able to make more efficient use of capital.  Germany was not weighted down with an expensive worldwide empire that needed defense. Following Germany's annexation of [[Alsace-Lorraine]] in 1871, it absorbed parts of what had been France's industrial base.<ref>Broadberry and O'Rourke (2010)</ref>

By 1900 the German chemical industry dominated the world market for [[Dye|synthetic dyes]]. The three major firms [[BASF]], [[Bayer]] and [[Hoechst AG|Hoechst]] produced several hundred different dyes, along with the five smaller firms. In 1913 these eight firms produced almost 90 percent of the world supply of dyestuffs, and sold about 80 percent of their production abroad.  The three major firms had also integrated upstream into the production of essential raw materials and they began to expand into other areas of chemistry such as [[Drug|pharmaceuticals]], [[photographic film]], [[Agrochemical|agricultural chemicals]] and [[Electrochemistry|electrochemical]]. Top-level decision-making was in the hands of professional salaried managers, leading Chandler to call the German dye companies "the world's first truly managerial industrial enterprises".<ref>Chandler (1990) p 474-5</ref> There were many spin offs from research—such as the pharmaceutical industry, which emerged from chemical research.<ref>Carsten Burhop, "Pharmaceutical Research in Wilhelmine Germany: the Case of E. Merck," ''Business History Review''. Volume: 83. Issue: 3. 2009. pp 475+. in [[ProQuest]]</ref>

==Belgium==
[[History of Belgium|Belgium]] during the [[Belle Époque]] showed the value of the [[History of rail transport|railways]] for speeding the Second Industrial Revolution. After 1830, when it [[Belgian Revolution|broke away from the Netherlands]] and became a new nation, it decided to stimulate industry. It planned and funded a simple cruciform system that connected major cities, ports and mining areas, and linked to neighboring countries. Belgium thus became the railway center of the region. [[History of rail transport in Belgium|The system]] was soundly built along British lines, so that profits were low but the infrastructure necessary for rapid industrial growth was put in place.<ref>Patrick O’Brien, ''Railways and the Economic Development of Western Europe, 1830–1914'' (1983)</ref>
