Fradkin, Efim Samoilovich 

Born Feb. 24, 1924, in the village of Shchedrin, in what is now Gomel’ Oblast, Byelorussian SSR. Soviet physicist. Corresponding member of the Academy of Sciences of the USSR (1970). Member of the CPSU since 1945.

From 1942 to 1947, Fradkin served in the Soviet Army. In 1948 he graduated from the University of L’vov. That same year he began working at the Institute of Physics of the Academy of Sciences of the USSR. His major works are devoted to quantum field theory, quantum statistics, and hydrodynamics. Fradkin has used the methods of functional analysis in the theory of relativists fields. He developed a modified perturbation theory for the theory of interacting particles. He obtained renormalized field theory equations and studied their solution. He also introduced functional methods into quantum statistics, in which he developed the diagram technique.

Fradkin received the State Prize of the USSR in 1953. He has been awarded three orders and several medals.
