Mordechai Gebirtig (Yiddish: מרדכי געבירטיג), born Mordecai Bertig (4 May 1877 – 4 June 1942), was an influential Polish Jewish poet and songwriter of the interwar period. He was shot by Germans in the Kraków Ghetto, occupied Poland, during the Holocaust.[1] A number of his Yiddish songs are sung to this day, including Es brent, Reyzele, Moyshele Mayn Fraynd, and Kinder Yorn.
