"Frederick Law Olmsted was among the first to regard landscape architecture as a profession and a fine art – in fact, with Calvert Vaux he virtually created that profession.  Olmsted was also, far and away, the most eminent and successful person ever to practice it in this country. He was co-designer of Central Park, head of the first Yosemite commission, leader of the campaign to protect Niagara Falls, designer of the U.S. Capitol Grounds, site planner for the Great White City of the 1893 World’s Columbian Exposition, planner of Boston’s 'Emerald Necklace' of green space, and created park systems in many other cities." - pbs.org
