Brown University president Christina Paxson was part of an interesting forum in the Atlantic Monthly’s March edition. The question asked of a group of intellectuals and academic historians was: What day most changed the course of history?
Ken Burns, the documentary film maker, said it was June 28, 1914, the day Archduke Franz Ferdinand was assassinated, which started World War I. Yale history professor Paul Kennedy said it was the day Thomas Newcomen invented the steam engine.
