Frederick Law Olmsted (April 26, 1822 – August 28, 1903) was an American landscape architect, journalist, social critic, and public administrator. He is popularly considered to be the father of American landscape architecture. Olmsted was famous for co-designing many well-known urban parks with his senior partner Calvert Vaux, including Prospect Park and Central Park in New York City, as well as Elm Park (Worcester, Massachusetts), considered by many to be the first municipal park in America. Other projects that Olmsted was involved in include the country’s first and oldest coordinated system of public parks and parkways in Buffalo, New York; the country’s oldest state park, the Niagara Reservation in Niagara Falls, New York; one of the first planned communities in the United States, Riverside, Illinois; Mount Royal Park in Montreal, Quebec; the Emerald Necklace in Boston, Massachusetts; Highland Park in Rochester, New York; Belle Isle Park, in the Detroit River for Detroit, Michigan; the Grand Necklace of Parks in Milwaukee, Wisconsin; Cherokee Park and entire parks and parkway system in Louisville, Kentucky; the 735 acre Forest Park in Springfield, Massachusetts, featuring America’s first public „wading pool”; the George Washington Vanderbilt II Biltmore Estate in Asheville, North Carolina; the master plans for the University of California, Berkeley, the University of Maine, and Stanford University near Palo Alto, California as well as for The Lawrenceville School; and Montebello Park in [[St. Catharines]], Ontario. In Chicago his projects include: Jackson Park; Washington Park; the Midway Plaisance for the 1893 World’s Columbian Exposition; the south portion of Chicago’s „emerald necklace” boulevard ring; Anderson Park in Upper Montclair, New Jersey; Cadwalader Park in Trenton, New Jersey; and the University of Chicago campus. In Washington, D.C., he worked on the landscape surrounding the United States Capitol building. The quality of Olmsted’s landscape architecture was recognized by his contemporaries, who showered him with prestigious commissions. His work, especially in Central Park in New York City, set a standard of excellence that continues to influence landscape architecture in the United States. His second line of achievement involves his activism in conservation, including work at Niagara Falls, the Adirondack region of upstate New York, and the National Park system.
