Hennes Weisweiler (1919-1983) - “The Don”: no FC coach was more successful than Don Hennes. With the 1977 cup win and the 1978 Double, he shaped the last truly successful phase in Köln history, when the club belonged among Germany’s and Europe’s elite. The charming Stollwerck chocolate commercials came included. Weisweiler died of a heart attack in 1983.
