Mordechai Gebirtig (), born Mordecai Bertig (4 May 1877 – 4 June 1942), was an influential Polish poet and songwriter of the interwar period. He was shot by Germans in the Kraków Ghetto, occupied Poland, during the Holocaust. A number of his Yiddish songs are sung to this day, including Es brent, Reyzele, Moyshele Mayn Fraynd, and Kinder Yorn. Life Mordechai Gebirtig was born in Kraków under the Austrian Partition, and lived in its Jewish working-class quarter all his life. He served for five years in the Austro-Hungarian army. Gebirtig became a renowned folk artist in Yiddish literature and song while in Kraków. He was self-taught in music, played the shepherd's pipe, and tapped out tunes on the piano with one finger. He earned his livelihood as a furniture worker; while music and theatre were his avocations. His life ended in the Nazi shooting action carried out in the Kraków Ghetto on the infamous "Bloody Thursday" of June 4, 1942. Gebirtig belonged to the Jewish Social Democratic Party, a political party in Galicia which merged into the Jewish Labour Bund after World War I. The Bund was a Yiddishist proletarian socialist party, which called for Jewish cultural autonomy in a democratic Second Republic. Music From 1906 he was a member of the Jewish Amateur Troupe in Kraków. He also wrote songs and theater reviews for , the Yiddish organ of the Jewish Social-Democratic Party. It was in such an environment that Gebirtig developed, encouraged by such professional writers and Yiddishist cultural activists as Avrom Reyzen, who for a time lived and published a journal in Krakow. Gebirtig's talent was his own, but he took the language, themes, types, tone, and timbre of his pieces from his surroundings, in some measure continuing the musical tradition of the popular Galician cabaret entertainers known as the Broder singers, who in turn were beholden to the yet older and still vital tradition of the badchen's (wedding jester's) improvisatory art. Style of folk songs He published his first collection of songs in 1920, in the Second Polish Republic. It was titled Folkstimlekh ('of the folk'). His songs spread quickly even before they were published, and many people regarded them as folksongs whose author or authors were anonymous. Adopted by leading Yiddish players such as Molly Picon, Gebirtig's songs became staples of numerous regular as well as improvised theatrical productions wherever Yiddish theatre was performed. It
