Froebel's Gifts
"In the late 1700s, a young man named Friedrich Froebel was on track to become
an architect when a friend convinced him to pursue a path toward education

Friedrich Froebel created kindergarten. If you've ever looked at a piece of
abstract art or Modernist architecture and thought "my kindergartener could have
made that," well, that may be more true than you realize."
