Chaimas Burin (1920–?) was born in Vilnius into the family of Zofija and Elijus Burin. From 1930 to 1932, he attended the Gymnasium of the Society of Educators in Vilnius, and from 1932 to 1938, he studied at the Julius Slovackis Gymnasium in Vilnius. While studying in the gymnasium, he worked as a tutor. In 1938, Burin applied to study at the Medical Department of the Faculty of Mathematics and Natural Sciences of Stefan Batory University but was not accepted “on the grounds of nationality” (based on the inscription in the application document). Later he filed a repeated application for admission to the Department of Biology of the Faculty of Mathematics and Natural Sciences and was accepted. In 1939, Burin applied for a transfer to the Medical Department of the Faculty of Mathematics and Natural Sciences, and his application was successful. However, in December, the faculty was closed down. He wanted to continue his studies at Vytautas Magnus University, but, as he himself stated in his resume, he was not accepted again and “again on the grounds of nationality”. In 1940, Burin was learning Lithuanian and was working in the editorial office of the newspaper “Liaudies laikraštis”, and as a translator in the press office of the Vilnius Branch of the Trade Union Centre. In 1940, he applied to study at the Medical Department of the Faculty of Mathematics and Natural Sciences and was accepted. However, it was not possible for him to complete his studies because, on 19 September 1941, he was expelled from the university on the basis of the Order of 17 September 1941 of the Department of Higher Education of the Board of Education, which was subordinate to the National Socialists. No further information on the fate of Chaimas Burin is known.
