America's most celebrated architect spent more time designing colleges than attending them. Frank Lloyd Wright was admitted to the University of Wisconsin-Madison in 1886, but left after only one year. He would move to Chicago and eventually apprentice under Louis Sullivan, the "father of modernism." By the time of his passing, Wright's resume included more than 500 works, most famous of which are Fallingwater and New York City's Solomon R. Guggenheim Museum.
