Guillaume de l'Hôpital is the shortened version of his full name and title, which was: Guillaume-François-Antoine Marquis de l'Hôpital, Marquis de Sainte-Mesme, Comte d'Entremont and Seigneur d'Ouques-la-Chaise.
Some sources omit the hyphens: Guillaume François Antoine Marquis de l'Hôpital.
His name is alternatively rendered l'Hospital, which was how he himself rendered it -- however, the French language changed and the silent s was changed to a circumflex.
Whether the surname is prefixed with an uppercase L or not is also variable: l'Hôpital or L'Hôpital.
