Though it is a handsome village, with stately trees and often-generous lawns, Oak Park has neither major waterways nor dramatic vistas. But it is rich in figures of historical importance such as Ernest Hemingway, Doris Humphrey, Edgar Rice Burroughs, Percy Julian, Ray Kroc, and William Barton. It is also blessed with the world's largest concentration of Prairie School buildings designed by Frank Lloyd Wright and his followers. The Oak Park community has nurtured such innovation with one hand while fiercely holding on to its own identity with the other, negotiating its relationship with Chicago and facing down a century and a half of constantly-shifting challenges.
