The art collection of the late John Whitehead, former chairman of Goldman Sachs, is being offered as the cornerstone in Christie's Impressionist and Modern Art sale this May in New York.

The 90 piece estate, with rare works by Claude Monet, Vincent Van Gogh, Amedeo Modigliani, and Pierre Bonnard, is expected to achieve over $40 million in sales.

Whitehead served in the U.S. Navy during World War II, where he commanded a landing craft at Omaha Beach, in the D-Day invasion of Normandy.
