Frederick Law Olmsted Jr. (1870-1957) was an American landscape architect best known for his wildlife conservation efforts.
He had a lifetime commitment to national parks, and worked on projects in Acadia, the Everglades and Yosemite National Park. Olmsted Point in Yosemite and Olmsted Island at Great Falls of the Potomac River in Maryland are named after him. He and his brother John C. Olmsted created Olmsted Brothers as a successor firm to their father's.
By 1920, his better-known projects included plans for metropolitan park systems and greenways across the country. In 1928, while working for the California State Park Commission, Olmsted completed a statewide survey of potential park lands that defined basic long-range goals and provided guidance for the acquisition and development of state parks, and was a founding member and later president of the American Society of Landscape Architects.
