How Many Grades Did He Save?

Students thanking a long-dead French mathematician is peak calculus energy! Guillaume de l'Hôpital didn't just give us fancy wigs and aristocratic vibes—he gave us l'Hôpital's Rule, the emergency room for indeterminate limits (0/0 or ∞/∞) that's been rescuing desperate calculus students since 1696. Nothing says "mathematical hero worship" like thanking a guy who basically paid someone else (Johann Bernoulli) to figure out the math, slapped his name on it, and has been saving GPAs for 300+ years. The beard guy is all of us at 3 AM before the final, whispering gratitude to a portrait we've never actually seen before that moment.
