Mania Lifšicaitė was born on 1 January 1910 in Horodets (Belarus), Navahrudak voivodeship (one of the documents in her personal file indicates 25 December 1910 as her date of birth). Her father Jankelis Mejeris was from Turetsk (Russia) and her mother’s name was Dina. Mania grew up with a brother and six sisters. In 1927, she finished the Adam Mickiewicz Gymnasium in Vilnius, and a year later passed her graduation examinations in the humanities. In 1928, she became a student in the Faculty of Law of the Vilnius Stephen Bathory University, where she studied until 1934, when due to personal reasons she had to suspend her studies. On 8 December 1934, she gave birth to a daughter. On 4 September 1940, she re-applied to study in the third year of the Faculty of Law of Vilnius University but her application was rejected as at that time she was already married and did not have Lithuanian SSR citizenship. She re-applied again in October and was admitted to the sixth semester. On 19 September 1941, Mania Lifšicaitė-Balberiškienė was expelled from the Faculty of Law of Vilnius 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 and enforced their policies. She was imprisoned in the Vilnius Ghetto during the Second World War and most likely was killed together with her daughter Janna.
