Around April 1906, he met Pablo Picasso, who was 11 years younger than Matisse. The two became lifelong friends as well as rivals and are often compared. One key difference between them is that Matisse drew and painted from nature, while Picasso was more inclined to work from imagination. The subjects painted most frequently by both artists were women and still lifes, with Matisse more likely to place his figures in fully realised interiors. Matisse and Picasso were first brought together at the Paris salon of Gertrude Stein with her companion Alice B. Toklas. During the first decade of the twentieth century, the Americans in Paris—Gertrude Stein, her brothers Leo Stein, Michael Stein, and Michael's wife Sarah—were important collectors and supporters of Matisse's paintings. In addition, Gertrude Stein's two American friends from Baltimore, the Cone sisters Claribel and Etta, became major patrons of Matisse and Picasso, collecting hundreds of their paintings and drawings. The Cone collection is now exhibited in the Baltimore Museum of Art.
