Abstract painter, New York, N.Y.
Born in Germany, Bauer's work in non-objective painting was promoted by Solomon R. Guggenheim's art advisor, and later museum director, curator Hilla Rebay, and Bauer became a paid advisor to Solomon R. Guggenheim and Rebay in the formation of the Solomon R. Guggenheim Foundation (1937), later the Museum of Non-Objective Painting (1939), and then after Guggenheim's death, the Solomon R. Guggenheim Museum (1949). Guggenheim and Rebay later dropped him due to Bauer's intense criticism of the Foundation and Rebay.
