Murray Gell-Mann
He is particularly well known for his role in bringing organization into the world of subatomic particles, which before his work seemed to be verging on chaos, and for developing the concept of quarks. In the latter part of his career his focus has shifted from the most basic aspects of nature to complex adaptive systems, which he currently explores at the Santa Fe Institute.
Gell-Mann was born in New York City on September 29, 1929. His father, Arthur Gell-Mann, ran a language school, but was knowledgeable in a wide range of subjects. The younger Gell-Mann was significantly influenced by his father, not only displaying a lifelong fascination with languages, but also cultivating his own array of erudite interests. As a child prodigy, Gell-Mann taught himself calculus and considered pursuing a career in ornithology, linguistics or archaeology, though his father convinced him that to do so would most certainly mean a life of relative poverty.

Murray Gell-Mann
American theoretical physicist (1929–2019)
Murray Gell-Mann (; September 15, 1929 – May 24, 2019)[3][4][5][6] was an American theoretical physicist who played a preeminent role in the development of the theory of elementary particles. Gell-Mann introduced the concept of quarks as the fundamental building blocks of the strongly interacting particles, and the renormalization group as a foundational element of quantum field theory and statistical mechanics. He played key roles in developing the concept of chirality in the theory of the weak interactions and spontaneous chiral symmetry breaking in the strong interactions, which controls the physics of the light mesons. In the 1970s he was a co-inventor of quantum chromodynamics (QCD) which explains the confinement of quarks in mesons and baryons and forms a large part of the Standard Model of elementary particles and forces.

(1929–2019), Inventor of Quarks
First Encounters
In the mid-1970s, particle physics was hot. Quarks were in. Group theory was in. Field theory was in. And so much progress was being made that it seemed like the fundamental theory of physics might be close at hand.
Right in the middle of all this was Murray Gell-Mann—responsible for not one, but most of the leaps of intuition that had brought particle physics to where it was. There’d been other theories, but Murray’s—with their somewhat elaborate and abstract mathematics—were always the ones that seemed to carry the day.
It was the spring of 1978 and I was 18 years old. I’d been publishing papers on particle physics for a few years, and had gotten quite known around the international particle physics community (and, yes, it took decades to live down my teenage-particle-physicist persona). I was in England, but planned to soon go to graduate school in the US,
