 (Electronics Physicist) 



B. A. Wwedensky was born April 19, 1893. After graduating 

 from Moscow University in 1915, he worked in several scien- 

 tific research organizations. From 1927 to 1935, he was at the 

 All- Union Electrotechnical Institute where he was made pro- 

 fessor in 1929. He worked at the Physics Institute of the 

 U.S.S.R. Academy of Sciences from 1941 until 1944. Wweden- 

 sky, in 1941-1944, served as a member of the Presidium of the 

 U.S.S.R. Academy of Sciences. In 1944-1951 he was Chairman 

 of the Section on Development of Problems in Ffadioengineering 

 of the U.S.S.R. Academy of Sciences and, in 1946-1951, he was 

 Academician Secretary of the Department of Technical Sciences 

 of the U.S.S.R. Academy of Sciences. He became a member, in 

 1949, of the main editorial board and the chief editor, in 1951, 

 of the Great Soviet Encyclopedia. Since 1959, he has been 

 Chairman of the Scientific Council of the Soviet Encyclopedia. 

 In 1953 he began working at the Institute of Radioengineering 

 and Electronics of the U.S.S.R. Academy of Sciences. Wweden- 

 sky was elected Corresponding Member of the U.S.S.R. Academy 

 of Sciences in 1934, and in 1943 Academician. In 1954 he be- 

 came a Corresponding Member of the German Academy of Sci- 

 ences, Berlin. He has received the following awards: in 1949 

 the Gold Medal of A. S. Popov; in 1952 the State Prize; in 1945 

 and 1953, the Order of Lenin; in 1953 and 1962, the Red Banner 

 of Labor. 



Wwedenskii's main work is concerned with the study of the 

 propagation of ultra-short waves, and also with investigations 

 in magnetism. Under his leadership an ultra-short wave broad- 

 casting station (RV-61) was built in 1929. In 1932-1933 he 

 organized expeditions for the study of the propagation of meter 

 and decimeter waves over the sea surface. The expedition 

 proved the possibility of the propagation of ultra short waves 

 beyond the horizon (diffraction propagation) and allowed a de- 

 termination of the relationship between the propagation of ultra 

 short waves and meteorological conditions (phenomenon of re- 

 fraction). Wwedensky introduced the "diffraction formula,"
