Whos the scientist discovered Quark Theory

Question

.........

Answer 1

Murray Gell-Mann and Kazuhiko Nishijima

Answer 2

There are many "quark theories" but the notion of quarks evolved out of a classification of hadrons developed independently in 1961 by Murray Gell-Mann and Kazuhiko Nishijima, which nowadays goes by the name of the quark model. The scheme grouped together particles with isospin and strangeness using a unitary symmetry derived from current algebra, which we today recognize as part of the approximate chiral symmetry of QCD. This is a global flavor SU(3) symmetry, which should not be confused with the gauge symmetry of QCD.

Answer 3

well, i havent heard about any of them. so just check the link.
