Yitzchak Lowy (1887–1942), also known as Yitskhok Levi, Jizchak Löwy, Jacques Levy, Djak Levi, was a Polish Yiddish theater actor.
Lowy was born in Warsaw, Poland. In 1907, he joined a Yiddish theater troupe and toured Europe. From October 1911 through 1912, the troupe stayed in Prague, where Lowy became good friends with Austrian-Czech writer Franz Kafka.
From the Warsaw Ghetto, it is likely that he was deported in the summer of 1942 and then murdered in the Treblinka extermination camp.[1]
