No one understood airports quite like Eero Saarinen. His swooping Dulles International Airport turned 50 over the weekend and its uplifting form is still inspiring today. Saarinen was quite proud of it, too, declaring the building “the best thing I have ever done.” The control tower and main terminal building at Dulles opened on November 17, 1962, formally dedicated by President John F. Kennedy. The airport was named for Secretary of State John Foster Dulles. Also, if you’re in Los Angeles, be sure to check out the A+D Architecture and Design Museum’s exhibition on Saarinen, now up through January 3rd.
