Maurer was the son of the local cobbler, and known as an amateur violinist, actor, and singer.
When the famous Vilnius Jewish Theatre (Vilna Troupe), under the direction of Zygmund Turkow visited Boryslav in 1922, the 16-year-old Yoshe was offered a minor role.
As a member of this famous Yiddish Theatre, he toured Poland and Romania until 1927, when he immigrated to Argentina.
He was regarded as a first class "character" (drama) actor and as a "tour de force" used to change leading roles, for example, playing with Ben Ami both parts of Man and Devil in Got, Mentsch Und Taivel, the famous Yiddish version of Faust by Jacob Gordin, night after night.
In the late nineteen-forties, he was elected President of the Jewish Actors Guild in Argentina and served in this post for more than 20 years, until his emigration to Israel.
