Arnold Stang, 91, an actor who appeared alongside Milton Berle and Frank Sinatra and was known for his nerdy looks and distinctive nasal voice, died Sunday of pneumonia at a Massachusetts hospital, said JoAnne Stang, his wife of 60 years. He lived in the Boston suburb of Needham for the last decade.

JoAnne Stang attributed her husband's career longevity to his willingness to tackle any professional challenge.

He played alongside Berle on radio and television in the 1950s, starred as Sinatra's sidekick in the 1955 movie The Man With the Golden Arm," and was a member of the ensemble comedic cast of It's a Mad, Mad, Mad, Mad World in 1963.

He voiced cartoons, including the lead character in the 1960s cartoon Top Cat, and did dozens of commercials, perhaps most notably for the Chunky candy bar.

He continued acting into his 80s, playing a role in the 1993 movie Dennis the Menace. - AP
