Sergei Romanovich Zarapkin

from Wikipedia, the free encyclopedia

Sergei Romanowitsch Zarapkin ( Russian Сергей Романович Царапкин , scientific transliteration Sergej Romanovič Carapkin ; * 1892 ; † January 15, 1960 ) was a Russian geneticist and biologist. Zarapkin was a student of the Moscow population geneticist Sergei Tschetwerikow .

life and work

Zarapkin was a geneticist with an extremely good knowledge of mathematics. In particular, he had specialist knowledge in the field of statistics, which was very beneficial to his mutation research. After completing his biology studies, Zarapkin began to work at the Moscow Institute of Experimental Biology directly under Nikolai Konstantinovich Koltsov . In 1926, at the request of Oskar Vogt , Zarapkin was sent to Germany to the Kaiser Wilhelm Institute for Brain Research in Berlin-Buch. He moved to Berlin with his wife Aleksandra Sergeevna and three children. He worked there with Helena and Nikolai Timofejew-Ressovsky . Relations with Nikolai Timofeev, in particular, did not turn out to be the best. Zarapkin and other laboratory workers gave Timofejew scientific materials for presentation at the 1932 International Congress of Genetics in the United States. Timofejew obviously did not correctly portray the authors of the research papers and the research. After his return to the USSR in 1945, Zarapkin was sentenced to ten years in a labor camp. He was sent to the same camp as Nikolai Timofejew-Ressovsky. While Timofejew was released from the camp after a year and was able to continue research within the Russian nuclear project, Zarapkin was held in the camp for ten years under the most difficult conditions. The Zarapkin family moved to Ryazan in 1957 . Zarapkin finally died on January 15, 1960 after a heart attack due to his bad health from being held in the camp.
