Zeller was drafted into the German army, and lost his right arm on the Soviet front of World War II.[1] He earned his Ph.D. from the University of Tübingen in 1950, under the supervision of Konrad Knopp and Erich Kamke,[2] and remained at Tübingen for most of his career as a professor and as director of the computer center. He left Tübingen in 1959 for a professorship in Stuttgart but returned to Tübingen in 1960 with a personal chair in "the mathematics of supercomputer facilities" (German: Mathematik der Hochleistungsrechenanlagen), making him one of the founders of computer science in Germany.
