Gibson died late Monday night after a short battle with cancer at his home in Malibu, said his son, Jon.
Gibson, who more recently played a recurring role as cantankerous Judge Clark Brown on Boston Legal," was part of the original ensemble cast of Laugh In," which ran on NBC from 1968 to 1973.
The hour-long show, whose original cast included Goldie Hawn, Judy Carne, Ruth Buzzi, Arte Johnson, Jo Anne Worley and others, was an immediate hit.
Henry was an integral part of 'Laugh-In' for a long time, and he was brilliant," said Gary Owens, the show's announcer, who remained close to Gibson over the years. He was a very funny man."
George Schlatter, the executive producer and creator of Laugh-In," recalled that when Gibson auditioned for the show, He came in and did a poem and a full back flip. He said, 'Is that anything?' I said, 'Be here Monday.'
Gibson, Schlatter said, brought a wonderful warmth and whimsy and a charm to 'Laugh-In.' That went a long way to balance some of the political, satirical and bawdy humor we featured.
