Gertrude Stein's personality has dominated the provenance of the Stein art legacy. It was, however, her brother Leo who was the astute art appraiser. Alfred Barr Jr., the founding director of New York's Museum of Modern Art, said that between the years of 1905 and 1907, " was possibly the most discerning connoisseur and collector of 20th-century painting in the world." After the artworks were divided between the two Stein siblings, it was Gertrude who moved on to champion the works of what proved to be lesser talents in the 1930s. She concentrated on the work of Juan Gris, André Masson, and Sir Francis Rose. In 1932, Stein asserted: "Painting now after its great period has come back to be a minor art."
