1970s: M*A*S*H
Morgan's first appearance on M*A*S*H was in the show's third season (1974–1975), when he played eccentric Major General Bartford Hamilton Steele in "The General Flipped at Dawn", which originally aired on September 10, 1974.
The following season, Morgan joined the cast of M*A*S*H as Colonel Sherman T. Potter. Morgan replaced McLean Stevenson, who had left the show at the end of the previous season. Col. Potter was a career army officer who was a firm yet good-humored, caring father figure to the people under his command.
In 1980, Morgan won an Emmy award for his performance on M*A*S*H. When asked if he was a better actor after working with the show's talented cast, Morgan responded, "I don't know about that, but it's made me a better human being." After the end of the series, Morgan reprised the Potter role in a short-lived spinoff series, AfterMASH.
Morgan also kept busy appearing in several Disney movies throughout the decade, including The Barefoot Executive, Snowball Express, Charley and the Angel, The Apple Dumpling Gang, The Cat from Outer Space (opposite McLean Stevenson) and The Apple Dumpling Gang Rides Again.
