Which New York skyscraper did Georgia O'Keeffe paint in her 1927 architectural works?

Georgia O'Keeffe painted the Radiator Building in her 1927 architectural works. The building, officially the American Radiator Building, stood at 40 West 40th Street in Manhattan and was designed by Raymond Hood and André Fouilhoux.

O'Keeffe's New York paintings often emphasized towering structures, dramatic viewpoints, and strong geometric shapes. Her 1927 painting Radiator Building—Night used dark architectural forms and vivid red accents to transform the skyscraper into a nearly symbolic modernist image.

The work belongs to a period when O'Keeffe was closely associated with New York's modern urban landscape. Her paintings did not simply document buildings as an architectural survey might; they heightened scale, color, and mood.

The Radiator Building is often confused with the Chrysler Building or the Empire State Building because all three are famous New York skyscrapers associated with the city’s machine-age skyline. O'Keeffe's named subject, however, was the American Radiator Building, recognizable for its black facade and glowing red details.
