Did Greene live and work in New York? Did she attend art school?
Yes, Gertrude Greene was a native New Yorker whose parents owned a department store in Brooklyn. She studied art at the Leonardo da Vinci Art School in Manhattan.
Her husband, Balcomb Greene, was also a well-known artist who explored abstraction in his art. He gave this work to the Brooklyn Museum.
Another quick note: her maiden name was Gertrude Glass.
