Richard M. Cohen, an outspoken and award-winning television news producer whose career was eventually derailed by the ravages of multiple sclerosis, which he wrote about in a best-selling memoir, died on Dec. 24 in Westchester County. He was 76.

Mr. Cohen spent more than 20 years in the news business, working with luminaries like Ted Koppel at ABC and Walter Cronkite and Dan Rather at CBS. But his memoir, Blindsided: Lifting A Life Above Illness, and articles for HuffPost, The New York Times and other publications dealt with M.S., a degenerative disease of the central nervous system. In spite of compromised body functions, he worked into the mid-1990s as a producer for CBS News, CNN, PBS and FX.

Mr. Cohen was married to Meredith Vieira, a former “Today Show” host.
