On March 12, 1876, George Bergstrom was born in Neenah, Wisconsin. He became an architect best known for designing the Pentagon, the headquarters of the U.S. Department of Defense. The Pentagon’s design and construction during World War II created one of the largest office buildings in the world. Bergstrom’s layout emphasized efficiency, internal courtyards, and interconnected corridors. His work helped solve the challenge of coordinating a rapidly expanding military bureaucracy. The building has since become a symbol of American military power and planning.
