The airport was named after his brother John Foster Dulles who was Secretary of State for Eisenhower. I remember his name being bandied about in the 50's, but don't know much about him. I do know he was involved in the Dawes Act which allowed U.S. banks and firms to loan money to Germany after WWI to help the country pay their war reparations, and help rebuild its economy. But then along came Hitler, and Germany never paid back those loans, and it took almost 100 years for Germany to pay their WWI reparations in full.
According to Wikipedia, he played a part in the coup in Iran that brought the Shah of Iran to power. As Secretary of State he was involved in the affairs of other foreign countries like Vietnam in the 50's, Asia and the Pacific, Egypt, and Guatamala. He was Secretary of State from 1953 to 1959.
Very interesting, thanks!
