Isaac Dudley Fletcher

Isaac Dudley Fletcher (May 13, 1844 – April 28, 1917) was an American businessman, art collector and museum benefactor.

Native of Bangor, Maine, he settled in New York in 1865 and was a member of the Lotos and Union League clubs.

He had the mansion built that is called today the Harry F. Sinclair House. He was president of Barrett Manufacturing Company which distributed asphalt and acquired a large art collection which he bequeathed to the Metropolitan Museum of Art.

According to the Frick library, he owned work by "David, Gainsborough, Rembrandt, Reynolds, and Rubens, Alexander H Wyant, Corot and Daubigny". The "work by David" referred to the Portrait of Charlotte du Val d'Ognes, which at the time of the bequest in 1917 was still attributed to Jacques-Louis David, but since 1995 has been attributed to Marie-Denise Villers.

Besides the collection itself, the bequest included a large sum of money to start a fund for the purchase of art. According to the 1994 Museum guidebook, several of the paintings listed were purchased through the Fletcher Fund, most notably the Portrait of Juan de Pareja.
