Abraham Teitelbaum was born on March 1, 1889 in Warsaw, Poland. Inspired to enter the theater by seeing actors rehearsing at his parents’ restaurant, he became a young follower of the Warsaw Yiddish theater. Teitelbaum eventually joined choral and dramatic troupes and got his first theatrical job as a prompter in 1907. He got his first break on the stage the following year.
Over the course of the next few years, he joined a number of other troupes and with them traveled to Paris, London, and Buenos Aires. Right after World War I, Teitelbaum served as the director of the Peretz Society Drama studio before becoming the theatrical director of the Yiddish dramatic society of Minsk.
