M. was born on 27 February
191, in Tarnopol, Galicia, to simple, pious parents. His
father was a wholesale glass dealer.
Until age eleven he learned
in a cheder, later in a small Talmud with tsufus, and
he had the opportunity -- privately -- to learn German
and Polish. Often he used to "gorglen" himself,
and he thought that he would become a prayer leader.
By the outbreak of the World
War he wandered with his family, and after several
months they came to Vienna. There B. learned further for
about a year in a Beit HaMedrash.
In 1915 his father was taken
into military service, and the fourteen-year-old B. had
to become the income earner at home. He took up various
trades, and he earned money. He caught himself at times
in the Yiddish theatre in the play "Shalom bit".
Since then he became a frequent attendee of the theatre,
a bky in the play, and was able to oysveynik from an entire role.
In 1917 B. traveled around
in a dramatic club of the "Tsion" union, and he acted
for the first time as "Aaron Shiper" in Dymov's "Shma
Yisrael" under Jacob Mestel's direction. From there he
participated in the weekly literary productions of
Mestel and Itzhak Deutsch's professional productions.
