Doctor's father was a
kosher meat tax collector, and until the age of fourteen he had a traditional Jewish education in a
Cheder. At some point in the 1890s, possibly 1896, he emigrated to
England, where he began his involvement in the musical theater while supporting himself as a hairdresser. He met many of the actors in the London Yiddish Theater milieu and eventually made his debut as the character Marcus in
Abraham Goldfaden's
The Sorceress. == Musical career ==
