Born on 8 December 1909 in Warsaw, Poland, more than three months later he immigrated with his parents to Belgium, and there he lived until 1914, and he fled to London, England. His father, a prompter in Yiddish theatre in Poland, went back to his profession in the local "Pavilion" Theatre. G. as a seven-year-old debuted in a children's role with the guest-starring Jacob Silbert in "The Devil's Power".

In 1920 the family returned to Belgium, where his father became a prompter in the various Yiddish troupes, and G. was enlisted as an actor with the guest-starring: Jacob Silbert, Hymie Prizant, Anna and Hymie Jacobowitz, Rochelle Rosenfeld, Moris Novikov, Lidia Potocka, Irving Jacobson and Mae Shoengold. In 1926, when a part of the split "Vilna Troupe" (under the direction of Jacob Weislitz, Chewel Buzgan and David Shapiro) came to act in Belgium, G. received the opportunity to act with them in the plays "Shrey khine", "Der dybuk", "Tog un nakht", "Der toyber", "Kiddush Hashem", "Bunt in oysbeserungs-hoyz" and "Hershele ostropoler".

In 1936 he returned to London and acted for three seasons under the direction of Fanny Waksman in the "New Yiddish National Theatre", performing with an entire range of guest-stars from America. In 1939, he acted in London's "Grand Palais Theatre", where he performed at the end of December in the title role of S. J. Harendorf's successful play "The King of Lampedusa". In March 1944 he was mobilized into the English army, where he served until the end of the Second World War, then began to perform with word concerts to benefit Jewish organizations.
