Last evening on NPR's Weekend Edition, Michel Martin, in reporting that Lin-Manuel Miranda had the night before made his final performance in the hit musical Hamilton, reflected on "what Alexander Hamilton's story can teach us after a troubling week of news." Her thoughts are well worth listening to or reading, and both can be done here. This morning, a post on Facebook brought Alexander Hamilton to mind again. It was on this day, July 11, in 1804 that Aaron Burr shot Hamilton in a duel. Hamilton died the next day.
