LOS ANGELES -- The brother of Bob Einstein says the comedy veteran known for "The Smothers Brothers Comedy Hour" and "Curb Your Enthusiasm" has died. He was 76.

Einstein's younger brother, filmmaker and actor Albert Brooks, posted a tweet Wednesday in which he said Einstein "will be missed forever."

Brooks called Einstein a great brother, father and husband as well as a "brilliantly funny man."

Einstein created and played the spoof daredevil character Super Dave Osborne, who appeared on comedy-variety shows and specials.

Einstein played Marty Funkhouser on Larry David's "Curb Your Enthusiasm."
