'''Murray Gell-Mann''' ([[Manhattan]], [[New York]], [[15. rujna]], [[1929.]] – [[24. svibnja]], [[2019.]]) bio je [[SAD|američki]] [[fizičar]], dobitnik [[Nobelova nagrada|Nobelove nagrade]] [[1969.]] za doprinose na teoriji [[elementarne čestice|elementarnih čestica]].

Rođen je u [[Židovi|židovskoj]] obitelji i bilo je "čudo od djeteta". Upisao se na [[Sveučilište Yale]] s 15 godina, a s 23 godine je započeo revoluciju u shvaćanju elementarnih čestica.

Gell-Mann's work in the [[1950s]] involved the understanding of a class of then newly discovered [[elementary particles]] which came to be called [[kaon]]s and [[hyperon]]s. Classifying these particles led to the idea of a new [[quantum number]] called [[strangeness]]. One of Gell-Mann's triumphs is the [[Gell-Mann–Nishijima formula]], which was, initially, a formula from empirical results, but was later explained by the quark model. Gell-Mann and [[Abraham Pais]] were involved in explaining many puzzling aspects of the physics of these particles.

In [[1961.]], this led him (and [[Kazuhiko Nishijima]]) to introduce a classification of elementary particles called [[hadron]]s (also independently proposed by [[Yuval Ne'eman]] at around the same time). This scheme is now explained by the [[quark model]]. Gell-Mann's own name for the classification scheme was the ''[[Eightfold way (physics)|eightfold way]]'', because of the ''octets'' of particles in the classification, and also after the [[Noble Eightfold Path|eightfold way of Buddhism]] &mdash; a choice that is reflective of Gell-Mann's interests.{{Fact|date=February 2007}}

Gell-Mann, and, independently, [[George Zweig]], then went on, in 1964, to postulate the quark model. This introduced [[quark]]s, the particles of which the [[hadron]]s were composed, a name coined by Gell-Mann through a reference to the book ''[[Finnegans Wake]]'', written by [[James Joyce]] ("Three quarks for Muster Mark!" - book 2, episode 4).  Zweig had referred to the particles as "aces" but Gell-Mann's name caught on.

Quarks were soon accepted to be the underlying elementary objects in the study of the structure of hadrons. 
In 1972 he introduced with [[Harald Fritzsch]] the quantum number 'color' and later, in a joint paper with Heinrich Leutwyler, the full theory of [[quantum chromodynamics]] (QCD) was released. 
The quark model is part of QCD, and has been robust enough to survive the discovery of other [[flavour (particle physics)|flavour]]s of quarks.
