Something wrong?His name is on the rule every calculus student learns for rescuing limits that collapse into 0/0 - except he didn't invent it. He published it first, in 1696, and that was enough to make it his forever.

About this person
Guillaume François Antoine, Marquis de l'Hôpital was a French mathematician born 7 June 1661. In 1696 he published Analyse des Infiniment Petits pour l'Intelligence des Lignes Courbes, the first systematic exposition of differential calculus in print. The treatise introduced l'Hôpital's rule - the technique for calculating limits involving indeterminate forms 0/0 and ∞/∞ - though the rule itself originated elsewhere. The book went through several editions and translations, becoming the model for how calculus would be taught for generations. He died 2 February 1704, his name sealed to a method he made canonical but did not create.
