On July 3, 1839, in Lexington, Massachusetts, Cyrus Peirce opened the first state normal school in America, and three students showed up. That room is the ancestor of every education school in the country. The episode traces the invention of teacher training from La Salle's seminary in Reims and Prussian models to Samuel Read Hall's Vermont school and Horace Mann's campaign.
La Salle's Reims house is called the first normal school only retrospectively, and rival claimants exist. Historians also stress that Massachusetts normal schools were short-course and inspired by, not copied from, Prussian seminaries, and Hall's credit for inventing the blackboard is folklore.
