Gustave Dreyfus [1837-1914], Paris; his heirs; purchased with the entire Dreyfus collection 9 July 1930 by (Duveen Brothers, Inc., London, New York, and Paris); sold 31 January 1944 to the Samuel H. Kress Foundation, New York;  gift 1957 to NGA.  The Duveen Brothers Records document the firm’s sixteen year pursuit and eventual acquisition of the Dreyfus collection, which included paintings, sculptures, small bronzes, medals, and plaquettes. Bequeathed as part of his estate to Dreyfus’ widow and five children (a son and four daughters), who had differing opinions about its disposition, the collection was not sold until after his widow’s death in April 1929. Duveen did not wish to separate Dreyfus’ collection of small bronzes, medals, and plaquettes, and it was sold intact to the Kress Foundation for a price that was met by installment payments every three months.
