The Olmsted Brothers company was an influential landscape architectural firm in the United States, formed in 1898 by brothers John Charles Olmsted (1852–1920) and Frederick Law Olmsted, Jr. (1870–1957), who were the sons of the eminent landscape architect Frederick Law Olmsted.
The Olmsted brothers inherited the nation's first landscape architecture business from their father Frederick Law Olmsted. This firm was a successor to the earlier firm of Olmsted, Olmsted and Eliot after the death of their partner Charles Eliot in 1897. The two brothers were among the founding members of the American Society of Landscape Architects (ASLA) and played an influential role in creating the National Park Service. Prior to their takeover of the firm, Frederick Law Olmsted Jr. had worked as an apprentice under his father, helping to design projects such as Biltmore Estate and the World's Columbian Exposition before graduating from Harvard University. The firm employed nearly 60 staff at its peak in the early 1930s. Notable landscape architects in the firm included James Frederick Dawson and Percival Gallagher. The last Olmsted family member in the firm, Frederick Law Olmsted, Jr., retired in 1949. The firm itself remained in operation until 1980.
Office and archives
"Fairsted", the firm's 100-year-old business headquarters and design office, has been carefully preserved as the Frederick Law Olmsted National Historic Site, located on 7 acres (2.833 ha) of landscaped grounds at 99 Warren St., Brookline, Massachusetts. It offers excellent insights into the practice of large-scale landscape design and engineering. The site also houses an archive (access by appointment only) of the firm's designs, plant lists, and photos for hundreds of projects.
The Olmsted Brothers completed numerous high-profile projects, many of which remain popular to this day, including park systems, universities, exposition grounds, libraries, hospitals, residential neighborhoods and state capitols. Notable commissions include the roadways in the Great Smoky Mountains and Acadia National Parks, Yosemite Valley, Atlanta's Piedmont Park, a residential neighborhood in Oak Bay, British Columbia, Canada: Uplands; entire park systems in cities such as Portland and Seattle, and Washington state's Northern State Hospital. The Olmsted Brothers also co-authored, with Harland Bartholomew, a 1930 report for the Los Angeles Chamber of Commerce entitled "Parks, Playgrounds, and Beaches for the Los Angeles Region" encouraging the preservation of outdoor public space in southern California. The report was largely ignored by the city, but became an important urban planning reference.
