Gösta Prüzelius (1922-2000) was a Swedish actor who dubbed Grover and Count von Count on Sesam. He continued to dub Grover on Svenska Sesam and as late as the 1990s Sesam version (dubbed from the Open Sesame package). His full name was Karl Gösta Prüzelius.
Prüzelius had a long and sucessful career behind him. He graduated from acting school in Göteborg and made his theater debut in 1943. His first of many film credits was the 1946 movie Bra tidning blir bättre, and he became a frequent player in the works of Ingmar Bergman, including films, radio, stage plays, and commercials.
He quickly established himself as a desired voice actor due to his distinctive voice as both dubbing actor and as narrator. He was one of two narrators for the dub of the 1966 documentary John F. Kennedy: Years of Lightning, Day of Drums. He was heard in Disney's The Jungle Book (Bagheera), One Hundred and One Dalmatians (Towser), Sleeping Beauty (narrator), and Mulan (The Emperor).
