What is the nickname of the American Radiator Building in New York?

The American Radiator Building is nicknamed the Black Tower.

The nickname reflects the building’s striking appearance: its 23-story tower is faced largely in black brick and trimmed with gold-colored ornament. Raymond Hood and André Fouilhoux designed it for the American Radiator Company, using color as both architecture and corporate advertising.

The black-and-gold palette was intended to evoke coal and fire, the materials and forces associated with radiator heating. The gold effect was produced with bronze powder applied to cast stone rather than solid gold. Its dramatic silhouette and Gothic-influenced Art Deco detailing made it one of Manhattan’s most recognizable early skyscrapers.

The building was completed in 1924 at 40 West 40th Street, just south of Bryant Park. It was later renamed the American Standard Building after the American Radiator Company merged with Standard Sanitary Manufacturing. The “Black Tower” nickname refers to the original building’s appearance, not a separate structure.
