The bequest was revealed in a will filed yesterday in New York by her attorneys. Clark, 104, had an extensive art collection in her 42 room apartment on Fifth Avenue. The art, including works by Renoir and John Singer Sargent, is being transferred to a new foundation, the Bellosguardo Foundation named after her 24 acre estate in Santa Barbara, Calif. The fund to promote the arts and the art will be housed there, according to the will, as well as rare books and a Stradivarious violin.

The Monet was the only work separated from the collection. The small 1907 canvas was purchased in 1930 by Clark from Monet’s gallery in Paris. It was last publicly displayed in 1925.

“Water Lilies” a series of 250 oil paintings, is one of the most famous masterpieces in the world. Monet, a beloved impressionist painter, was inspired, and never tired, of his flower garden at Giverny.

Though Clark hadn’t been seen in public in decades, she had close family ties to the Corcoran. Her father, William Andrews Clark, a copper, timber and railroad tycoon and former senator, gave his entire extensive art collection to the Corcoran in 1925. The holdings of European art included 200 paintings, among other works. The museum built and named a wing after Clark. His daughter had exhibited seven of her own paintings at the Corcoran in 1929.

Huguette Clark, whose wealth was estimated at nearly $400 million, had no descendants.
