Natalie Griffin de Blois was an American architect. Entering the field in 1944, she became one of the earliest prominent women in the male-dominated profession. She was a partner for many years in the firm of Skidmore, Owings and Merrill. Her notable works include the Pepsi Cola Headquarters, Lever House, and the Union Carbide Building in New York City, the Equitable Building in Chicago, the low-rise portions of the Ford World Headquarters in Dearborn, Michigan, and the Connecticut General Life Insurance Company Headquarters in Bloomfield, Connecticut. Several of de Blois' buildings are among the tallest woman-designed buildings in the world. She later taught architecture at the University of Texas in the 1980s and 1990s.
