Harry Morgan, 'M*A*S*H*' Star, Dies at 96 - The Hollywood Reporter: Harry Morgan, who was best known for his long-running portrayal of the fatherly Colonel Potter on M*A*S*H*, died at his Los Angeles home Wednesday morning at 96 years old. Morgan won an Emmy in 1980 for his performance as the unflappable medic.
A veteran of more than 50 years in films and TV, Morgan starred or co-starred in 11 TV series. He was an appealing Everyman whose calm manner and wry delivery were widely popular. In M*A*S*H*, his steady ways and wry humor tempered the more high-keyed natures of his co-star’s characters, Hawkeye Pierce and Trapper John. He went on to co-star in its spin-off, AfterMASH (1984-85).
