http://en.wikipedia.org/wiki/Bundt_cake

The Bundt pan (a registered trademark) was created in 1950 by H. David Dalquist, founder of Nordic Ware, at the request of members of the Hadassah Society's chapter in Minneapolis, Minnesota. They were interested in a pan that could be used to make bundkuchen (sometimes called kugelhopf or Gugelhupf), a popular German and Austrian coffee cake.
