Career
Gellesch played for Football Club Schalke 04 (1926–1946) and TuS Lübbecke (1946–1950). One of the many talents emanating from Football Club Schalke 04 during the 1930s, young Rudolf Gellesch replaced Fritz Szepan as inside forward after Szepan had moved to the center half position. Being a talented threader of moves on the pitch, he appeared to be a double of Szepan.
