Marquis de Sade (1740 - 1814)
ezs note: This is a new piece, borrowing Wikipedia's list of anniversaries of LGBT+ and advocates. This is a wide list, but it is by no means exhaustive. You can help by adding to the list of notables. In the meantime, enjoy!
PS - Yeah, yeah, I know - de Sade is definitely not everyone's taste. But look at philosophers who look at de Sade with varying degrees of respect. You may disagree with de Sade's work, but look at the philosophers as well.
