Jupp Schlösser was born on July 26, 1902, in Cologne, Germany. Schlösser was a singer and songwriter specialized in Kölsch Karnevalsschlager. After working as a baker and streetcar driver, he transitioned to songwriting in 1938 upon meeting composer Gerhard Jussenhoven. Together, they authored more than 50 songs in the Kölsch dialect, including "Die Hüsjer bunt om Aldermaat" (1938) and "Die hinger de Jadinge ston un spinxe" (1939), which addressed social informants during the Nazi era. Schlösser also achieved success with high-German tracks such as the Schunkelwalzer "Kornblumenblau" (1937), which sold 12 million copies. He was awarded the Willi-Ostermann-Medaille and was honored by the Kölner Rote Funken in 1967. Schlösser died on February 23, 1983.
