David Ogden Stiers, the tall, balding, baritone-voiced actor who brought articulate, somewhat snobbish comic dignity to six seasons of the acclaimed television series “M*A*S*H,” died on Saturday at his home in Newport, Ore., a small coastal city southwest of Salem. He was 75.

His death was announced on Twitter by his agent, Mitchell K. Stubbs, who said the cause was bladder cancer.

Mr. Stiers joined the cast of “M*A*S*H” in 1977, when Larry Linville, who had played the pompous and inept Maj. Frank Burns, left the show. The series, a comedy-drama set in a Mobile Army Surgical Hospital during the Korean War, required a foil for its raucous, irreverent, martini-guzzling leads, Hawkeye Pierce (Alan Alda) and B.J. Hunnicutt (Mike Farrell), and Mr. Stiers’s imperious Maj. Charles Emerson Winchester III seemed to fit the bill.
