Nelson, the last surviving member of the show's classic, mid-century nuclear family, passed away due to complications from colon cancer, according to his publicist, Dale Olson.
Besides starring on the show and eventually directing several episodes over its run, Nelson also appeared in movies such as "Peyton Place" and worked as a producer in the 1970s and 80s.
He is survived by his second wife, Yvonne, four sons, a daughter and seven grandchildren. His brother, Ricky, died in a 1985 plane crash.
