221 LIFSHITS 



LIFSHITS, IL'YA MIKHAILOVICH (Physicist) 



I. M. Lif shits was born in 1917. In 1936 he graduated from 

 the Khar'kov State University, and in 1938 from the Khar'kov 

 Mechanico- Machine -Building Institute. He started, in 1937, as 

 a scientific worker, and in 1941, became a section chief at the 

 Ukraine S.S.R. Academy of Sciences Physico-Technical Insti- 

 tute in Khar'kov. Also in 1941 he received his Doctor of Sci- 

 ence Degree. In 1944 he became Chairman of the Theoretical 

 Physics Department of Khar'kov State University. He is a 

 Corresponding Member of the Ukrainian SSR Academy of Sci- 

 ences and was elected, in 1960, a Corresponding Member of the 

 U. S.S.R. Academy of Sciences. In 1952 Lif shits was awarded 

 the Mandelshtam Memorial Prize of the U. S.S.R. Academy of 

 Sciences for work on dynamic theory of nonideal crystals. For 

 his research on electronic structure of metals, he received, in 

 1961, the Simon Memorial Prize of the Physical Society of 

 London. 



Lifshits' works deal with the theory of solid state physics 

 and low temperature physics.
