BRUK, ISAAK SEMYONOVICH (Electrical Engineer) 



I. S. Bruk was born November 9, 1902. He graduated from 

 the Moscow Technical College in 1925, and has been working at 

 the U.S.S.R. Academy of Sciences Institute of Energetics since 

 1935. In 1956, he became Chief of the U.S.S.R. Academy of 

 Sciences Laboratory on Directing Machines and Systems, and 

 later was made Director of the Institute. He was elected, in 

 1939, to the U.S.S.R. Academy of Sciences as a Corresponding 

 Member. 



Bruk has worked on power electric and mathematical ma- 

 chines. In 1936-38, the first U.S.S.R. machines for integrating 

 ordinary differential equations were built according to the de- 

 sign of Bruk. A computing device, "computing table of alternat- 

 ing current" for investigating electrical systems was built in 

 1945-1947 under his leadership. From 1948 he has conducted 

 work on high speed electronic computers. The M-1, M-2, M-3 

 machines were built in 1950-55.
