Alfrederick Smith Hatch (1829–1904) was a prominent Wall Street broker in the firm of Fisk and Hatch and president of the New York Stock Exchange from 1883 to 1884. Like many of his business associates, he was an enthusiastic collector of art. One of the finest paintings in his collection was this commissioned group portrait showing three generations of his family. It depicts them in the library of their New York residence at 49 Park Avenue, on the northeast corner of 39th Street. Hatch is seated to the right at his desk, and his wife, the former Theodosia Ruggles (1829–1908), leans on the mantel. Other members of the family, including Theodosia's mother, Hatch's father, and their children are also present. (https://www.metmuseum.org/art/collection/search/11263)
