  Leptons are a class of subatomic particles which are fundamental constituents of matter. These particles include electrons, taus, muons, and their neutrino counterparts.

Discovery of Leptons
 The first lepton to be discovered was the electron. It was discovered in 1897 by a team of British physicists led by J.J. Thomson. 33 years later, the neutrino was postulated by Wolfgang Pauli to help account for certain the conservation of certain observed properties after beta decay. At the time Pauli did not know that there is more than one flavor of neutrino. Carl D. Mason discovered the muon in 1936

Electron
 The electron is the most well known of the leptons, given that it was the first discovered, and everyone knowingly interacts with the particles every day. It is the least massive. It's antiparticle is the positron, and it's complementary particle is the electron neutrino.
