Frederick Law Olmsted and his son, Frederick, Jr., were honored when Tioga Road opened to automobile traffic in 1961. Olmsted senior, born in 1822 and died in 1903, was considered the father of American landscape architecture and was best known for designing New York’s Central Park. He served as chairman of the first commission to manage Yosemite Valley and the Mariposa Grove and wrote a report recommending policy for the care and protection of Yosemite’s scenery and wildlife, a work considered a classic national park treatise. Frederick Law Olmsted, Jr., born in 1870 and died in 1957, also worked in landscape architecture, collaborated with the National Park Service, served on the Yosemite Advisory Board, and maintained a lifelong commitment to conservation, including contributing the guiding language in the legislation that established the National Park Service in 1916.
