"Aside from being a legendary television producer and prolific writer, Stephen was also a devoted husband, loving father and grandfather, and a loyal friend," his family said in a statement issued to the Los Angeles Times. "Mr. Cannell is survived by his high school sweetheart and wife of 46 years, Marcia; their three children, Tawnia, Chelsea and Cody; and three grandchildren. Stephen was a pillar of strength within his family and he touched everyone he met. He will be most deeply missed."
