17th century French composer, for those of you not in the know, and nominee for Lamest Death Ever.
Lully was conducting a piece at a concert in honor of Louis XIV recovering from illness-- and before I go any further, yes, that beeping is the irony detector going off. Anywho, in the 17th century, conductors kept time by pounding a big stick against the floor, instead of waving a little stick, as is the modern fashion. Lully botched, as the gamers say, and pounded his conducting staff on his foot. The resulting wound developed gangrene, Lully refused to have his foot amputated, and he died. Because he was a dumbass. Twice over.
