Boris Jakowlewitsch Kogan

Boris Jakowlewitsch Kogan ( Russian Борис Яковлевич Коган ; born October 8, 1914 in Kishinev ; † April 2012 ) was a Soviet-American physicist .

He studied natural sciences and received his diplomas in 1938 from the Electrotechnical Institute in Kharkiv . From 1940 to 1981 he worked at the Institute for Control Technology in Moscow . There he built the first laboratory for computer simulations in the Soviet Union . In 1945 he obtained a doctorate on a topic of automatic control at the Institute for Automation and Telemechanics of the Academy of Sciences of the USSR in Moscow. In the same year he became a candidate for technical sciences at the Academy of Sciences of the USSR. His appointment as professor at the physical-technical institute in Moscow took place in 1956. In 1962 he obtained a further doctorate in technical sciences at the Academy of Air Force of the USSR in Moscow in the subject of computer science.

From 1948 to 1980 he also worked at the Institute of Physics and Engineering in Moscow. As director of the laboratory for computer simulations, he was appointed chairman of the institute for computer technology and technical means of automation. He also held the post of deputy chairman of the National Committee of the USSR for analog computers and hybrid computers . Furthermore, he was a member of the editorial board of the magazine Automation and Telecontrol Technology .

In his scientific work he devoted himself to the development of machine methods for simulating automatic control systems. He mainly worked on the theory and planning of analog and hybrid computers. Under his leadership, the first analog computer was built in the Soviet Union, after which a series of other computers of this type was developed. The HRS-100 computer system for a hybrid computer was developed as part of a joint project with Yugoslavia . For his work in the field of analog computers he received the State Prize of the USSR in 1951 .

With his monograph on computer simulation and its application for automatic control tasks, he received international recognition, which was reflected in translations of this work in Hungary, China, Romania, Poland and the USA.

In 1987 he went to the USA to the University of California, Los Angeles , where he continued his scientific work. His focus there was on researching the mechanisms of fibrillation of the heart muscle . He contributed to the publication of the journal Transactions of the Society for Computer Simulation and was a member of the American Heart Association and the Society for Computer Simulation . His publications include 120 articles and two monographs.
