Academy of Sciences and in 1946 Academician. He was a re- 

 cipient in 1951 of the A. S. Popov gold medal. 



Berg's scientific work deals with: designing and developing 

 of tube oscillators; stabilizing frequency; studying amplification 

 and frequency control of tube oscillators. He formulated and 

 worked out a number of important problems (grid detection; the 

 computation of an oscillator with a distorted pulse form of the 

 anode current) which contributed to the development of radio 

 engineering. Berg is the author of many textbooks in the field 

 of radioengineering. 



As of 1961, Berg was chairman of the Cybernetics Council 

 of the U.S.S.R. Academy of Sciences.

I. S. Beritashvili was born December 29, 1884. In 1910 he 

 graduated from Petersburg University. He became a professor 

 in 1919 at Tbilisi University. In 1935 he was appointed head of 

 the Institute of Physiology at the University. This Institute be- 

 came a part of the Georgian S.S.R. Academy of Sciences in 1941, 

 and Beritashvili was the Director until 1952. Until recently he
