BURR, Aaron (1756-1836). Autograph letter twice signed (“A Burr”) to his uncle Pierpont Edwards, Philadelphia, 30 April 1794.

THE MAN WHO CHALLENGED ALEXANDER HAMILTON TO A DUEL AND WON. Burr writes to his cousin regarding financial matters. Pierpont Edwards (1750-1826) served in the Continental Army during the American Revolutionary War, later turning to politics which included serving as a delegate to the Congress of the Confederation and as U.S. district judge. Edwards was nominated by President Thomas Jefferson in 1806 to a seat on the United States District Court for the District of Connecticut. Burr, the nephew of Edwards, served as the third Vice President of the United States under President Thomas Jefferson from 1801 to 1805. He is perhaps most famously remembered for his duel with Alexander Hamilton in 1804, which resulted in Hamilton’s death and significantly damaged Burr’s political career. The duel and its aftermath led to Burr’s alienation from mainstream politics and contributed to his eventual downfall. Burr’s later years were marked by financial struggles and a failed attempt to establish a separate western nation, known as the Burr Conspiracy, which tarnished his reputation further.
