<human>:  Who came up with the quark model?
<bot>: The quark model was proposed by Murray Gell-Mann in 1964. He suggested that there are three fundamental particles: the electron, the neutrino, and the up quark. He also proposed that there were six more fundamental particles: the down quark, the strange quark, the charm quark, the top quark, the bottom quark, and the tau lepton.
