George Dudley Seymour (October 6, 1859 – January 21, 1945) was an American historian, patent attorney, antiquarian, author, and city planner.
George Dudley Seymour was born in Bristol, Connecticut, the son of Henry Albert Seymour and Electa Churchill. He practiced patent law in Washington, D.C., and then in New Haven, Connecticut. Seymour was a law graduate of Columbian College in Washington, D.C., and received an honorary Master of Arts degree from Yale University in 1913. He was a member of the Walpole Society, the American Antiquarian Society, the Century Association, the Cosmos Club, and the Acorn Club. Seymour was a former vice president of the American Federation of Arts, a trustee of the Wadsworth Atheneum, and chairman of the State Commission of Sculpture. He was a close friend of William Howard Taft, John Singer Sargent, and Gifford Pinchot, and a cousin of Yale President Charles Seymour.
Seymour extensively researched the life of the patriot Nathan Hale. He led the campaign for the statue of Hale on the Old Campus at Yale, and convinced the federal government to print a Nathan Hale postage stamp in 1925. In 1914, Seymour purchased the Nathan Hale Homestead in Coventry, Connecticut, which he restored and gifted to the Antiquarian & Landmarks Society. Upon his death, Seymour gifted to the United States government the life size bronze statue Captain Nathan Hale by sculptor Bela Lyon Pratt; the statue is located at the south facade of the United States Department of Justice headquarters in Washington, D.C.
Seymour was a leading figure in the municipal development of New Haven, and was the city's most fervent proponent of the City Beautiful movement. The City Beautiful influence in New Haven was responsible for a series of formal public buildings, such as the New Haven County Courthouse and the New Haven Free Public Library, with traditional columns and pediments that reinforced the role of the green as a civic center of classical dignity. In 1908, Seymour persuaded Yale to open the Peabody Museum of Natural History and the Yale University Art Gallery to the public on Sunday afternoons.
He died on June 21, 1945 in New Haven, Connecticut and was buried in the Grove Street Cemetery.
The George Dudley Seymour Papers, Seymour's collection of correspondence, writings, photographs, research files, and printed material, are housed within the Manuscripts and Archives in Sterling Memorial Library at Yale.
George Dudley Seymour State Park in Middlesex County, Connecticut is named after him.
