One of those strikingly familiar matrons you just can't place, character actress Mary Jackson is probably best known for her recurring role as one of the delightfully eccentric bootlegging sisters, "Miss Emily" Baldwin, on the series The Waltons (1971) that ran for nine seasons. She was born November 22, 1910 in rural Milford, Michigan, and earned a bachelor's degree from West Michigan University in 1932. A Depression-era school teacher for one year before pursuing her interest in theater, she returned to college (this time Michigan State University) in a fine arts program. She started out on the Chicago stage and in summer stock before migrating to the larger stages in New York and Los Angeles.

Film and TV roles did not come her way until well into middle age. Guesting on such TV shows as "The Andy Griffith Show," "The Twilight Zone," "My Three Sons," "Hazel," "The Mary Tyler Moore Show," "Barnaby Jones" and "Highway to Heaven," she usually appeared as ladylike small-town citizens. She was also part of the ensemble in Peter Bogdanovich's first low-budget film thriller Targets (1968), which was Boris Karloff's last feature. In the 70s she started gathering up character bits here and there, such as her nuns in the all-star epic Airport (1970) and the horror Audrey Rose (1977). A variety of pleasant, maternal parts came her way, including Lynn Carlin's mother in the Blake Edwards' western Wild Rovers (1971) and Jane Fonda's in the comedy caper Fun with Dick and Jane (1977). She supported Fonda again in the Vietnam-era drama Coming Home (1978), was among the cast in the cultish Big Top Pee-wee (1988) and had a noticeable role in Steve Martin's Leap of Faith (1992).
