Dorothy Brett - a Bloomsbury painter

Dorothy Brett was an upper-class gel who gave her parents trouble, but who got into the Slade School of Art at just the right time. She met Dora Carrington, became a 'crophead', and joined the fast set centred on Ottoline Morrell at her Garsington country estate. Yet Brett remained a virgin until she was forty, and after that went to live in the artists' colony in Texas founded by Mabel Dodge Luhan. And she stayed there for the rest of her life.
