Frederick Law Olmsted is arguably the most important historical figure that the average American knows the least about. Best remembered for his landscape architecture, from New York's Central Park to Boston's Emerald Necklace to Stanford University's campus, Olmsted was also an influential journalist, early voice for the environment, and abolitionist credited with helping dissuade England from joining the South in the Civil War. This momentous career was shadowed by a tragic personal life, also fully portrayed here.

Most of all, he was a social reformer. He didn't simply create places that were beautiful in the abstract. An awesome and timeless intent stands behind Olmsted's designs, allowing his work to survive to the present day. With our urgent need to revitalize cities and a widespread yearning for green space, his work is more relevant now than it was during his lifetime. Justin Martin restores Olmsted to his rightful place in the pantheon of great Americans.

Justin Martin is the author of three biographies, with Frederick Law Olmsted - landscape architect, abolitionist, journalist, renaissance man - as his latest subject. Earlier efforts: a national best-seller on Fed chairman Alan Greenspan and a life of Ralph Nader that served as a primary source for An Unreasonable Man, an Academy Award-nominated documentary. Martin is a former staff writer at Fortune magazine. His articles have appeared in a variety of publications including Newsweek, Money, and the San Francisco Chronicle.

Martin is a 1987 graduate of Rice University in Houston, Texas. He lives with his wife and twin sons in Forest Hills Gardens, New York, a landmark neighborhood designed by Frederick Law Olmsted Jr. In his spare time, Martin runs marathons (he's completed seven) and gardens (he's grown some great tomatoes, but his experiments in urban corn-growing have so far failed).
