Evgenii L'vovich Feinberg (27 June 1912 – 10 December 2005) was a Soviet physicist, recognized for his contributions to theoretical physics.
He was the son of a physician, born in Baku, moving to Moscow in 1918 where he graduated from Moscow State University as a theoretical physicist in 1935. He did research at the Lebedev Physical Institute in Troitsk, Moscow Oblast from 1938, where he published over a hundred works in his field.[1] Feinberg studied radio physics (wave propagation), statistical acoustics, the neutron, cosmic rays and particle physics. In his early years, he studied the beta-decay of ionized atoms (1939), inelastic coherent processes (1941) and inelastic diffraction processes (1954).
Feinberg headed the high-energy particle interaction research groups 1952–78. He was a guest professor at Nizhny Novgorod State University 1944–46 and a professor at his former school, Moscow Engineering Physics Institute 1946–54, which later became the Moscow Institute of Physics and Technology.
