Martin Lewis Perl
( June 24, 1927 - September 30, 2014) an American physicist. He received the 1995 Nobel Prize for Physics for discovering a subatomic particle that he named the "Tau", a massive lepton with a negative charge. The tau, which he found in the mid-1970s, was the first evidence of a third “generation” of fundamental particles, the existence of which proved essential for completing the so-called standard model of particle physics. Perl was jointly awarded the Nobel Prize with physicist Frederick Reines, who had discovered another subatomic particle, the neutrino, in the 1950s.
