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 instead.

Frank Lloyd Wright’s son, John, was an architect, but his most famous creation wasn’t a building. It was a toy set that kids have been playing with for over 100 years.
