J. was born on 11 June 1890 in Lodz, Poland. His father was a weaver. He learned in a cheder and then in Yarotshinski's school. As a youth he sang in the chorus of the synagogue under the direction of the conductor Derguzhanski, and in his early youth together with his father he attended the Yiddish theatre, that created in him a deep impression. At the age of fourteen he traveled to his uncle in Patterson (America), but a year later he came back to Lodz and entered into Rappel's in the Warsaw Muranover Theatre, where he debuted as "Tlmi" in Lateiner's "Ash Re". After acting there for a season, Y. went over to Sabsey in Vilna (1 1/2 years), then with Guzik (two years), four months with Fishzon, a half-year with Zhitomirsky. He acted with Yungv-ts-Young in Warsaw, toured across Russia as a co-director with Heymovitsh, Charaz and Samberg, and he acted later with Lopovski in Riga and Vilna. In wartime he acted in Lodz in vaudeville houses, and then became an impressario for an itinerant troupe across Poland, Germany, Belgium and Holland. Later he guest-starred in Paris with a united members troupe, three months in London with Dubovsky, and in April 1921 he traveled to America where he debuted in the Irving Place Theatre in Boimvol's "Vas-libe-ken" ("Madam Freyling"), then he acted theatre and vaudeville with Samashevsky, a season in Cleveland and Detroit, and until 1927 he staged by himself non-union troupes across the province.

He returned to Europe and Y. guest-starred in Antwerp, Berlin, Paris, circa ten months in Lodz, at the end of 1928 in Rumania, then again across Eastern and Western Europe. In 1932 he returned to America, where he acts in the province.
