Still returned to San Francisco, where he became a highly influential professor at the California School of Fine Arts (now San Francisco Art Institute), teaching there from 1946 to 1950. In 1950, he moved to New York City, where he lived most of the decade, the height of Abstract Expressionism, but also a time when he became increasingly critical of the art world. In the early 1950s, Still severed ties with commercial galleries. In 1961 he moved to a 22-acre farm near Westminster, Maryland, removing himself further from the art world. Still used a barn on the property as a studio during the warm weather months. In 1966, Still and his second wife purchased a 4,300-square-foot house at 312 Church Street in New Windsor, Maryland, about eight miles from their farm, where he lived until his death.
