Guillaume François Antoine, Marquis de l'Hôpital (1661 - February 2, 1704) was a French mathematician.

L'Hôpital is commonly spelled as both "L'Hospital" and "L'Hôpital" since the Marquis spelt his name with an 's'. However, the French language has since dropped the 's' (it was silent anyway) and replaced its preceding vowel with a circumflex. The circumflex ( ˆ ) is a diacritic mark used in written Greek, French, Esperanto, Norwegian, Romanian, Slovak, Vietnamese, Japanese romaji, Welsh, Portuguese, Italian, and other languages. ...

L'Hospital was born in Paris, France. He initially had planned a military career, but poor eyesight caused him to switch to mathematics. He solved the brachistochrone problem, independently of other contemporary mathematicians, such as Isaac Newton.

He is also the author of the first known book on differential calculus, L'Analyse des Infiniment Petits pour l'Intelligence des Lignes Courbes. Published in 1696, the text includes the lectures of his teacher, Johann Bernoulli, in which Bernoulli discusses the indeterminate form 0/0.
