Jakob Geis, stage name Papa Geis (27 December 1840, in Munich – 3 March 1908, in Munich) was a Munich performer, folksinger, and musical director. He was considered a master of Bavarian cuplés. The dramatist and director Jacob Geis was his grandchild. Originally he wanted to become a Catholic priest. But at the age of 26, he broke off his theological studies and started a stage career as a comedian in Vienna. He wore only black clothes, a bit like a Catholic priest. Often he was greeted therefore as a Father. His stage name Papa Geis means Daddy Geis.
