Born in 1891 in Lublin, Poland. His parents were bakers. Until age fourteen he learned in a cheder. He immigrated to London, England, and there he became a stand-in in Yiddish theatre ("Pavilion" with Sigmund Feinman). In 1911 he returned home and acted with amateurs. In 1913 he went away to serve in the Russian army, and after becoming free, he joined in the Lublin Yiddish theatre under the direction of Jacob Waxman, where he acted with Hershkovitsh, Shneck and Schilling. In 1918 he toured with a member troupe with Jacob Waxman, while making it through the eight Ukraine pogroms (Zlatopol, Novomirgrod, Cherkas, Uman, Yelisavetgrad, Nikolayev, Belaya Tserkow and Zhmerinke). Barely alive, he arrived in Odessa and from there toured with a member troupe across the Crimea with Brandesko and Vinokur, experiencing very bad times.

In 1920 he went to Constantinople, and from there to Bulgaria, then to Romania, where he acted with Kaner, Segalesko in Bucharest and Iasi, and he continued as a prompter with Askhenazy in Iasi, later with Kanapov, Jacob Kalich-Molly Picon, David Tselmeyster, Itsikl Goldenberg, Misha Fiszon and Breitman-Kanievska, then going through a tour (under the direction of Segal), with Dr. Baratov and later in Czernowitz with Reysh and then in other troupes.

According to Julian Schwartz, K. used to act part-time in episodic roles, and as the older actors Malvina Glikman left, he also helped as a bookkeeper for the management of the troupes in which he was participating. K. was a gentle, quiet, poor man. As a prompter, he gave respect to everyone. He never fought with anyone. He often experienced a difficult life and sometimes didn't have money for rent.
