Returning to Europe in 1906, he and his wife Dinah (formerly married to Jacob Adler) established a reputation in London and on the Continent. He played Othello in Romania, 1909, and died while rehearsing in Lodz. Manuscripts of Feinman's own plays and translations were acquired by the YIVO Institute.
