Typical of busy character actors, Fiedler made his face (and voice) recognizable to millions. Many know the bald-pated Fiedler as therapy patient "Mr. Peterson" on The Bob Newhart Show (1972); others might first recognize him for the 1968 movie, Drôle de couple (1968), and spin-off TV show, The Odd Couple (1970), or perhaps even from the Broadway play that preceded them. Even kids would know that helium-high voice from animated Disney features like Robin des bois (1973), Rox et Rouky (1981) and the "Winnie the Pooh" stories, in which he voiced "Piglet". The son of an Irish-German beer salesman, Fiedler knew he wanted to be an actor from his childhood days, when he had a full head of reddish-yellow hair. He made his first professional appearances onstage, branched out into live TV in New York and, then, during the 20 years he lived in Hollywood (1960-80), he turned up in many movies and an ever greater number of popular TV shows.
