MAKAREVSKII, ALEKSANDR IVANQVICH (Aeronautical 

 Engineer) 

 A. I. Makarevskii was born April 6, 1904. He graduated in 

 1929 from Moscow Technical School. In 1927 he began working 

 at the Central Aero-Hydrodynamic Institute and in 1950 became 

 Director of this Institute. In 1952 he was made professor at 

 the Moscow Physico-Technical Institute. He has been a mem- 

 ber of the Communist Party of the Soviet Union since 1943. In 

 1953 he was elected a Corresponding Member of the U.S.S.R. 

 Academy of Sciences. He was the recipient in 1943 of a Stalin 

 Prize. 



Makarevskii has investigated the external loads acting upon 

 aircraft in flight. He presented an analysis of possible over- 

 loads in the aircraft in connection with characteristics of the 

 stability and maneuverability of the aircraft. In his paper, 

 "Questions on Durability of an Aircraft at High Speeds" (1947) 

 he examined the influence of the compressibility of air on the 

 magnitude of aerodynamic loads. The most important result of 

 the works of Makarevskii was the establishment of domestic 

 standards on durability, including that of high speed aircraft. 

 He took part in compiling a work * Manual for Constructors" 

 (1940-42).

 Designer) 



D. D. Maksutov was born April 23, 1896. He graduated from 

 the Military Engineering School in 1914. In 1930 he organized 

 and directed the Laboratory of Astronomical Optics at the State 

 Optical Institute in Leningrad. In 1941 he became a doctor and 

 in 1944, a professor. He began working in 1952 at the Main 

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

 (Pulkova). In 1946 he was elected a Corresponding Member of 

 the U.S.S.R. Academy of Sciences. He received State Prizes in 

 1941 and 1946. 



Maksutov investigated the improvement of shadowing and 

 other optical methods, the technology of producing large, exact
