Bob Newhart, whose stammering, deadpan unflappability carried him to stardom as a standup comedian and later in television and movies, died on Thursday, according to a statement from his longtime publicist Jerry Digney. He was 94.

Over the course of five decades, Newhart's popularity rarely waned, whether it was as the recording star of the comedy album "The Button-Down Mind of Bob Newhart" (the first comedy album to win the Grammy for album of the year), the lead in two top-rated television sitcoms, or a supporting actor in movies including "Catch-22," "Cold Turkey" and "Elf."

He remains best known for the television shows, "The Bob Newhart Show" (1972-78) and "Newhart" (1982-90), both of which were built around his persona as a reasonable man put-upon by crazies.

Newhart was originally an accountant and advertising copywriter. He first rose to fame with his comedy album, 1960's "The Button-Down Mind of Bob Newhart." The album was a phenomenon of its time. It was one of the best-selling albums of the year, and it won multiple Grammy Awards.
