On 1 April 1920, Matisas and Chana Kodešas, the owners of a small shop in Vilnius, had a son, Dovydas. He went to a private lyceum of the Vilnius coeducational society Tarbut with instruction in Hebrew, and in 1939 passed the high school graduation examinations in the natural sciences. That same year, Dovydas became a student at the Vilnius Stephen Bathory University. After one semester he was transferred to the Vytautas Magnus University in Kaunas because the Polish-administered Stephen Bathory University was closed in 1939. He later continued his studies at the Lithuanian-administered Vilnius University. He studied geography in the Biology Department of the Faculty of Mathematics and Natural Sciences. He was expelled from the university on the basis of the Order of 17 September 1941 of the Higher Education Department of the Board of Education, which was subordinate to the Nazis. He was probably killed during the Holocaust.
