 Engineer) 



A. A. Blagonravov was born June 1, 1894. He is a graduate • 

 of the following institutions: the Mikhailovskoe School of Ar- 

 tillery (1916), Artillery College (1924), and the Military Techni- 

 cal Academy (1929). From 1929 to 1946 he was on the staff of 

 the Moscow Academy of Artillery and in 1938 was made a pro- 

 fessor there. He was President, in 1946-1950, of the Academy 

 of Artillery Science. Blagonravov was made Director of the 

 Machine Science Section of the U. S.S.R. Academy of Sciences in 

 1953. In 1957 he became Academic Secretary of the Technical 

 Science Division of the U.S.S.R. Academy of Sciences. He has 

 been a member of the Communist Party since 1937. In 1940 he 

 was given the permanent rank of lieutenant general in the ar- 

 tillery. Since 1943 he has been an Academician of the U.S.S.R. 

 Academy of Sciences. 



Blagonravov' s scientific contributions are in the field of 

 machinery and mechanics of armaments. His main work, Basic 

 Principals of Automatic Weapons (1931), is a valuable source 

 of fundamental calculations in the construction of weapons. 



In April 1962, Blagonravov was appointed Editor in Chief of 

 Izvestiya Akad. Nauk S.S.S.R., Otdel. Tekh. Nauk. He has 

 attended the Pugwash Conferences.
