Frederick Law Olmsted, America's preeminent landscape architect of the 19th century, designed dozens of parks, parkways and college campuses across the country. With Calvert Vaux, he created two of New York City's greatest parks -- Central Park and Prospect Park.Yet before Central Park, he had never worked on any significant landscape project and he wasn't formally trained in any kind of architecture.In fact, Fred was a bit of a wandering soul, drifting from one occupation to the next, looking for fulfillment in farming, traveling and writing.This is the remarkable story of how Olmsted found his true calling.The Central Park proposal drafted by Olmsted and Vaux -- called the Greensward Plan -- drew from personal experiences, ideas of social reform and the romance of natural beauty (molded and manipulated, of course, by human imagination).But for Olmsted, it was also created in the gloom of personal sadness. And for Vaux, in the reverence of a mentor who died much too young.PLUS: In celebration of the 200th anniversary of Olmsted's birth, Greg is joined on the show by Adrian Benepe, former New York City parks commissioner and president of Brooklyn Botanic Garden.boweryboyshistory.com
