Peter Capell (1912-1986) was a German actor who dubbed the voice of Pops in Die Muppet Show (the German version of The Muppet Show) and in the German dubs of The Great Muppet Caper and The Muppets Take Manhattan. He also dubbed the World's Oldest Fraggle in episodes of Die Fraggles (Fraggle Rock).
Although born and raised in Germany, Capell moved to the United States of America in 1933, working on stage and in radio in New York City. He was frequently heard as Nazis in wartime broadcasts such as Words at War and This Is Our Enemy, and served as producer on The Voice of America. Later radio credits included recurring roles on assorted soap operas, including Wendy Warren and the News (FBI Agent Anton Kemp), Front Page Farrell (Nick), Portia Faces Life (Dr. Byron), and When a Girl Marries (Officer Connolly). He also made many appearances on the science-fiction series Dimension X and its spin-off X Minus One, notably as Dr. Horst in Ray Bradbury's "Mars is Heaven," which he reprised in four different broadcasts of the tale.
Capell returned to Europe in 1955, but still appeared frequently in English-language films, including Paths of Glory, Billy Wilder's One, Two, Three (with Liselotte Pulver), and Willy Wonka and the Chocolate Factory (with Gene Wilder), as the eerie tinker encountered by Charlie at the factory gate. Apart from his Muppet work, his German dub credits include George Burns in Going in Style, the TV version of The Hitchhiker's Guide to the Galaxy (as Zarquon the Prophet), Anne of Green Gables (dubbing Richard Farnsworth), Star Trek (various guest roles), and the animated series Dr. Snuggles.
