I believe the most important decision taken anywhere by anyone in the 20th century was the decision about where to locate the Princeton Graduate College. President of the University Thomas Woodrow Wilson wanted it down on the campus, integrated with the undergraduate college. His nemesis, Dean Andrew Fleming West, wanted it where it now is, up on a little hill overlooking the Princeton golf course. President Woodrow Wilson had one of his characteristic snits, resigned as president, went into politics and ruined the 20th century.
