Debora Langbortaitė was born on 3 February 1921 in Vilnius where her father Aronas, a banker, and her mother Izerel Levin moved from Izabelin (Poland). Debora attended the primary school established by Sofija Gurevich in Vilnius and continued her education in the Sofija Gurevich Gymnasium until the 1933/1934 school year. From 1933–1939, she studied in the class of accelerated teaching of humanities at the coeducational gymnasium Oświata (Enlightenment) of the Vilnius Central Jewish Committee. In 1939, Debora studied in the Faculty of Agronomy of the Vilnius Stephen Bathory University; from 1940, she was an auditor in the Biology Department of the Faculty of Mathematics and Natural Sciences of Vilnius University, and several months later became a full-time student. After three semesters of studies, Debora Langbortaitė was expelled from the Biology Department of the Faculty of Mathematics and Natural Sciences of Vilnius University on 19 September 1941, 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. The Yad Vashem database indicates that she was imprisoned in the Vilnius Ghetto (the year of her birth is mistakenly given as 1923) and most likely killed. Her father Aronas Langbort was killed in Vilnius.
