Wirt, William (wûrt) [key], 1772–1834, U.S. Attorney General and author, b. Bladensburg, Md. He had little formal schooling but was admitted to the Virginia bar in 1792. His first book was an anonymous collection of sketches called The Letters of a British Spy (1803), which purported to be the work of a "meek and harmless" noble visitor to America. The Rainbow (1804) and The Old Bachelor (1810) are similar collections, attempting the style of Joseph Addison. Wirt's Life and Character of Patrick Henry (1817) was his first book to appear under his own name; it presumed to give the text of Henry's speeches. His role as prosecutor in the trial (1807) of Aaron Burr brought him renown as a lawyer. As U.S. Attorney General (1817–29), Wirt initiated the practice of preserving his official opinions so that they could be used as precedents. In 1832 he accepted the nomination for President of the Anti-Masonic party.
