A notice on Facebook from son Gary Dawson said the British-born comedian died at a Los Angeles hospital of complications from esophageal cancer, TMZ.com said Sunday.
"He was surrounded by his family," Gary Dawson wrote. "He was an amazing talent, a loving husband, a great dad, and a doting grandfather."
Dawson played British POW Cpl. Newkirk on the popular "Hogan's Heroes" sitcom in the 1960s and then moved on to host "Family Feud" from 1976-1985 and for one season in the 1990s. In between, he married Gretchen Johnson, whom he had met when she was a contestant on the program.
