The Seine at Port-Marly, Piles of Sand

Alfred Sisley was an Impressionist landscape painter, born in Paris to British expatriate parents. Considered the most consistent of the Impressionists in his dedication to painting en plein air (outdoors), Sisley's oeuvre comprises almost entirely landscapes, with his most important works including series of paintings around Hampton Court on the River Thames, the floods at Marly-le-Roi in 1875, and the Gothic church at Moret-sur-Loing. He also produced notable paintings portraying riverside scenes on the Seine in the suburbs west of Paris throughout his career.

The Seine at Port-Marly, Piles of Sand is an 1875 painting by Alfred Sisley. It was exhibited at the Exposition Universelle in 1900 whilst in the collection of Dr. Georges Viau, a Paris dentist and art collector. By 4 March 1907 it was owned by Durand-Ruel, who tried and failed to auction it on 4 March that year.

It was bought by the galerie Bernheim-Jeune in April 1920 and later by Martin A. Ryerson. In 1933 Ryerson left it to its present owner, the Art Institute of Chicago, where it is now in section 201 (Impressionists) on the 1st floor of the Art Institute of Chicago.
