Ann Brockman, oil and watercolor painter, was born in Alameda, California in 1896. She studied with painters Gifford Beal and John Sloan at the Art Students League in New York City. She exhibited at the Pennsylvania Academy, and with the Society of Independent Artists and Salons of America. She was an instructor at the Cape Ann School of Art at Rockport, Massachusetts, and spent much time painting in that location and on Cape Cod.
Kraushaar Galleries held a memorial exhibition of her paintings in 1946, three years after Ann Brockman's premature death at the age of forty-seven.
