 technologist) 



A. A. Kharkevich was born in 1904. In 1930 he graduated 

 from the Leningrad Electro- Technical Institute. He worked, 

 1932-41, at various teaching institutions of Leningrad, and from 

 1941-44 he was at the Phy si co- Technical Institute of Leningrad, 

 Kazan', and Moscow. From 1944-48, he was professor and de- 

 partmental head of the L'vov Polytechnical Institute, and from 

 1948-52, he was the departmental Director of the (Ukraine) 

 U.S.S.R. Academy of Sciences Institute of Physics in Kiev. In 

 1952-54, Kharkevich was professor and departmental chairman 

 of the Electro-Technical Institute of Communications in Mos- 

 cow. In 1954 he started to work in the Laboratory on the Treat- 

 ment of Scientific Communication Problems (now the Laboratory 

 on Systems of Information Transmission), where he became 

 Chief in 1957. He was elected in 1960 a Corresponding Member 

 of the U.S.S.R. Academy of Sciences. In 1962, Kharkevich was 

 appointed acting Director of the U.S.S.R. Academy of Sciences 

 Institute of Problems of Information Transmission. 



Kharkevich' s works deal with the theory, design and con- 

 struction of electro-acoustical apparatus.
