Career
His career started with South Dakota Düren 99. From 1953 to 1966 he played for 1. Football Club Köln as defender and midfielder.
Stollenwerk began his international career in 1951 playing as an inside right linkman.
He proved to be a versatile player, being used in every position, including goalkeeper. His main position, however, was that of an inside forward.
This changed in 1957, when 1. Football Club Köln coach Hennes Weisweiler converted Stollenwerk to right back.
This proved to be a good career move for him, as he felt at home in that role immediately and played convincingly enough to be called up again for international duty by Sepp Herberger.
Previously, as an inside forward, he was only sporadically used by Herberger. However, at the right back position Herberger was looking for a fitting successor to Jupp Posipal, who had quit his international career in 1956. By 1958, Stollenwerk had become the standard right back of West Germany, allowing Herbert Erhardt to play as center half instead of full back.
Stollenwerk retired from football in 1962, after winning the German football championship with 1.
Football Club Kölane Later on he was a trainer for Alemannia Aachen, TuS Langerwehe and 1.
