The world’s largest office building, The Pentagon, was completed just outside of Washington on this date during World War II. It was constructed under the supervision of John McShain, who was the builder of this and other iconic structures in Washington and Philadelphia. McShain attended–but never graduated from–La Salle College High School in Philadelphia, Class of 1917. He was a benefactor of the Christian Brothers and was named an Affiliated (Honorary) Brother.
