Henry Gibson, known for his comic poetry in "Rowan & Martin's Laugh-In," and his grumpy judge in "Boston Legal," ded Monday. He was 73.

Gibson had been fighting cancer.

Younger audiences know Gibson as Judge Clark Brown in "Boston Legal," the quirky lawyer dramedy that was known for its unique judges as well as out-of-this-world storylines. Despite the large stage presence of William Shatner and James Spader, and other interesting judges, some would say Clark Brown was one of the most popular characters on the show, and was a part of at least two dozen episodes.

Before finishing his career with "Boston Legal," Gibson made a name for himself in "Rowan & Martin's Laugh-In," where he was a part of the original cast. He also made guest appearances in a number of popular programs including "The Joey Bishop Show," "77 Sunset Strip," "Bewitched," "The Beverly Hillbillies," "Wonder Woman," "Knight Rider," "Star Trek: Deep Space Nine" and "Stargate SG-1."

Gibson is survived by his sons Jon, Charles and James, as well as three sisters, Adele Donahue, Mary Lee and Elizabeth Malloy.

His 40-year spouse Lois passed away in 2007.
