William J. Duane (1780–1865) was an Irish-born American politician and lawyer from Pennsylvania. Born in Clonmel, Duane emigrated to the United States with his parents and assisted his father in publishing the Aurora until 1806. After becoming an influential lawyer, he served several terms in the Pennsylvania General Assembly. Duane served as United States Secretary of the Treasury for some four months in 1833; his refusal to withdraw Federal deposits from the Second Bank of the United States led to his dismissal by President Andrew Jackson.Engraving: Bureau of Engraving and Printing; restoration: Andrew Shiva
