Paul Emile Duboy was the French-born New York architect whose defining commission is The Ansonia (1899–1904) at 2109 Broadway — among the most exuberantly ornamented residential buildings in the United States and one of the most architecturally and culturally consequential apartment hotels of the Beaux-Arts era. The Ansonia's curved corner massing, three-story mansard cap, ornamental balconies, and the Renaissance Revival surface program were unprecedented in their scale for a residential commission at the date of completion. The building's original program — apartment-hotel suites organized around shared services (concierge, restaurant, in-house laundry, even a rooftop farm at one point) — established a residential typology that influenced subsequent Upper West Side apartment-hotel commissions for decades. The 1992 condominium conversion preserved the building's defining architectural character; Duboy's exuberant facade vocabulary remains one of the most recognizable on the Broadway corridor.
