Murray Gell-Mann is an American physicist who may be best known for receiving the 1969 Nobel Prize in physics for his work on the theory of elementary particles.
Murray Gell-Mann and George Zweig (working independently) actually theorized quarks in 1964. The first of these six fundamental particles was observed (discovered or confirmed, if you like) in 1968, and the last was observed in 1995.
Murray Gell-Mann and Geroge Zweig, working independently, first propossed the quark theory in 1964. George Zwieg later won the Nobel Prize for advancement in physics with his discovery of the quark.

Quarks were discovered by using particle accelerators to smash subatomic particles. These particle accelerators, beginning with the machine at the Stanford Linear Accelerator Center (SLAC), accelerated charged particles to tremendous speeds and then forced them to collide with or smash into target material. The collisions cause protons and neutrons to break apart, and quarks were identified in the particle tracks as some of the "broken bits" that scattered following the collisions. The quark, which was proposed independently by physicists Murray Gell-Mann and George Zweig in 1964, was confirmed when investigators at SLAC found the first quark in 1968. It took until 1995 to identify the last type of quark when the top quark was spotted in collision results at Fermilab.

What do you mean with "did"? As of 2013, he still lives.
