William Edwards Cook (August 31, 1881 – November 10, 1959) was an American-born expatriate artist, architectural patron, and long-time friend of American writer Gertrude Stein.
Following his 1903 departure from the U.S., Cook resided in Paris, Rome, Russia, and on the island of Majorca, in the Balearic Islands off the eastern coast of Spain.
Today he is chiefly remembered not for his artistic achievements, but because, during World War I, he taught Stein to drive an automobile so that she could contribute to the French war effort, and because, in 1926, he commissioned the Swiss architect Le Corbusier (whose career was at an early stage) to design an innovative cubist home, on the outskirts of Paris, now called Maison Cook or Villa Cook.
