George Hadfield (1763 – 6 February 1826[1]) was born in Livorno, Grand Duchy of Tuscany, of English parents, who were hotel keepers.
He studied at the Royal Academy, and worked with James Wyatt for six years before emigrating to the United States.
He was the brother of painter, musician, and educator Maria Cosway.
He was appointed superintendent of the United States Capitol's construction on 15 October 1795,[2] and continued in that position until June 1798, resigning after an argument with William Thornton.
[3][4] He is credited with part of the design of the original Capitol building such as the north wing,[5][6][7] but little of the related papers remain.
