This engraving by John Chester Buttre is of President James Buchanan. This image was influenced from a daguerreotype by Mathew Brady. Buttre completed the engraving in the mid-19th century. Before being elected as the fifteenth president of the United States, Buchanan served as a member of the United States House of Representatives and Senate for the state of Pennsylvania, secretary of state, and the United States minister to Russia and Great Britain.
