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 Central Park in New York City. 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 (297 ha) 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.
New York City's Central Park
Andrew Jackson Downing, the charismatic landscape architect from Newburgh, New York, was one of the first who proposed the development of New York's Central Park in his role as publisher of The Horticulturist magazine. A friend and mentor to Olmsted, Downing introduced him to the English-born architect Calvert Vaux. Downing had brought Vaux from England as his architect collaborator. After Downing died in July 1852, in a widely publicized steamboat explosion on the Hudson River, Olmsted and Vaux entered the Central Park design competition together, against Egbert Ludovicus Viele among others. Vaux had invited the less experienced Olmsted to participate in the design competition with him, having been impressed with Olmsted's theories and political contacts. Prior to this, in contrast with the more experienced Vaux, Olmsted had never actually designed and executed a landscape design.  They were announced as winners in 1858. On his return from the South, Olmsted began executing their plan almost immediately. Olmsted and Vaux continued their informal partnership to design Prospect Park in Brooklyn from 1865 to 1873. That was followed by other projects. Vaux remained in the shadow of Olmsted's grand public personality and social connections.  The design of Central Park embodies Olmsted's social consciousness and commitment to egalitarian ideals. Influenced by Downing and his own observations regarding social class in England, China, and the American South, Olmsted believed that the common green space must always be equally accessible to all citizens, and was to be defended against private encroachment. This principle is now fundamental to the idea of a "public park", but was not assumed as necessary then. Olmsted's tenure as park commissioner in New York was a long struggle to preserve that idea.
