Josephine Gail "Jo" Baer (born August 7, 1929) is an American painter. She was born in Seattle, Washington. Baer is known for her works which are minimalist art.[1] She began showing her work at the Fischbach Gallery, New York, and other venues for contemporary art in the mid-1960s.[2]
In the late 1960s, Baer was experimenting with color and shifting the visual focus of her work. While working on the series The Stations of the Spectrum (1967-1969), Baer painted over their white surfaces to make them gray. In 1975 Baer was the subject of a retrospective at the Whitney Museum of American Art, New York, showcasing her Minimalist work.
