Natalie de Blois

Built World

Deceased (1921-2013)

For 60 years, the Union Carbide Building stood at 270 Park Avenue—a 52-story modernist landmark designed by pioneering woman architect Natalie de Blois. JPMorgan Chase demolished it and built something nearly twice as tall: a 1,388-foot supertall skyscraper that runs entirely on hydroelectric power and houses 14,000 employees.
