This sketch by Gaston Lachaise joined the collection in 1961. Lachaise was an American sculptor of French birth, active in the early 20th century. A native of Paris, he was most noted for his female nudes (source).
While the sketch above is the only work by Lachaise in the Mead’s collection, the Smith College Museum of Art collection holds two sculptures and a drawing by the artist:
Eternal Force, 1917
Seated Female Nude, n.d.
