Hans-Helmut Dickow
From Muppet Wiki
Hans Helmut-Dickow (1927-1989) was a German actor who appeared in dozens of German films and television series and played a Germanic Doc in the German version of Fraggle Rock.
At MuppetFest, Steve Whitmire reminisced about Dickow: "He'd been a Nazi solider, actually. Temperamental actor... Nice guy, but temperamental." The producers wanted him to play the role exactly as Gerry Parkes had in the North American version, but the German Doc refused to watch the North American shows. So on the first day, Dickow said his first line in German, and Whitmire was stuck playing Sprocket with no idea what Doc had just said.
Whitmire talked in great detail about his experiences on the set with Dickow to Duncan Kenworthy in the Fraggle Rock Season Two DVD Interviews segment titled "Docs And Sprockets".
