A landscape, portrait, marine and history painter, Edmund C. Coates lived in New York City during his active period 1837-1872. Brooklyn and New York City directories from those years list him as Edward, Edmund C., E.C. Coates, and E.G. Coates.

His paintings include landscapes of Canada and Italy although it is not known if the artist traveled to those countries or if other works inspired the scenes. He also painted in the White Mountains of New Hampshire and, listed as one of the Hudson River School painters, did numerous Hudson River Valley scenes such as Shipping on the Hudson River, 1855.

His painting titled Washington’s Headquarters at Newburgh, 1867, depicted a popular scene among the Hudson River painters because it was George Washington’s headquarters painted against the backdrop of Storm Mountain near the town of Newburgh.
