The Burr–Hamilton duel was a duel between two prominent American politicians, the former Secretary of the Treasury Alexander Hamilton and sitting Vice President Aaron Burr, on July 11, 1804. At Weehawken in New Jersey, Burr shot and fatally wounded Hamilton. Hamilton was carried to the home of William Bayard on the Manhattan shore, where he died at 2:00 p.m. the next day. ...
So now you know the significance of today's date ... just in case anybody asks.
