LINNIK, VLADIMIR PAVLQVICH (Physicist) 



V. P. Linnik was born July 6, 1889. In 1914 he graduated 

 from Kiev University. He began working at the State Optical 

 Institute in 1926. Until 1941 he was a professor at Leningrad 

 University. Since 1939 he has been an Academician of the 

 U.S.S.R. Academy of Sciences. Twice, in 1946 and in 1950, he 

 was awarded Stalin Prizes. 



Linnik' s research is in optics and its application in the 

 instrument-making industry. He constructed the following opti- 

 cal devices: a double microscope (1929), microinterferometer 

 (1933) for controlling the exactness of the processing of sur- 

 faces, a microscope for studying the surface of red-hot bodies, 

 interferometers for measuring double stars and the angular 

 diameter of the sun. He has developed methods of laboratory 

 investigation and testing of optical devices such as the aber- 

 ration of optical systems, the centering of optical systems, and 

 the assembling of microscope lenses. He designed control 

 devices for optical-mechanical industry. Linnik also worked 

 on the physics of X-rays and, in particular, on the investigation 

 of crystals with X-rays.
