The Pentagon Memorial was constructed from a design by Julie Beckman and Keith Kaseman of Philadelphia, Pennsylvania, with design support from Buro Happold and Fountains, that was chosen following a design competition. The design competition included a group of 11 judges, including Terence Riley, the chief curator of architecture and design at the Museum of Modern Art, and two former secretaries of defense, Melvin Laird and Harold Brown. They viewed 1,126 memorial proposals from around the world. Of the six international finalists selected, all were designers: Jean Koeppel and Tom Kowalski, Mason Wickham and Edwin Zawadzki, Jacky Bowring, Shane Williamson, Michael Meredith, and Julie Beckman and Keith Kaseman.
