by JOHN RICHARDSON
One of the most remarkable exhibitions in New York in recent years has been Four Americans in Paris - The Collections of Gertrude Stein and her Family, now at the Museum of Modern Art. In his report on the show John Richardson tells the fascinating story of how these pioneer American patrons of 20th-century art-Gertrude Stein , her brothers Leo and Michael, and her sister-in-law Sarah - built up their collection and how it was dispersed.
