Beginning in 1857 with the design for Central Park in New York City, Frederick Law Olmsted (1822–1903), his sons and successor firm created designs for more than 6,000 landscapes across North America, including many of the world's most important parks. Olmsted’s remarkable design legacy includes Prospect Park in Brooklyn, Boston’s Emerald Necklace, Biltmore Estate in Asheville, North Carolina, Mount Royal in Montreal, the grounds of the United States Capitol and the White House, and Washington Park, Jackson Park and the World’s Columbian Exposition of 1893 in Chicago. Olmsted’s sons were founding members of the American Society of Landscape Architects and played an influential role in the creation of the National Park Service.
The Passaic County Park System is clearly an important representation of the work of the Olmsted Brothers Firm, and important to the tradition of landscape architecture in the United States.
Goffle Brook Park, Garret Mountain Reservation, Weasel Brook Park, and the Dey Mansion Gardens were all designed by the Olmsted Brothers Firm.
