Eero Saarinen was a Finnish-American architect known for his sculptural and innovative designs. He studied in Paris and Yale and joined his father's architecture practice. Some of his most notable works include the TWA Terminal at JFK Airport, the Gateway Arch in St. Louis, and Dulles International Airport. For Dulles Airport, Saarinen designed a suspended terminal with a curved roof supported by tapered columns to give it an airy, modern feel and allow for future expansion. He incorporated innovative design elements like mobile lounges to efficiently move passengers from the terminal to planes. Saarinen's designs were defined by their sculptural forms and focus on how architecture could enhance human experience.
