Civic leaders beginning with the Reverend Thomas Lamb Eliot, a minister who moved to Portland in 1867, sought to create a natural preserve in the woods that eventually became Forest Park.[6] By 1899, Eliot's efforts led to the formation of the Municipal Park Commission of Portland, which in 1903 hired the highly regarded landscape architecture firm, the Olmsted Brothers of Brookline, Massachusetts, to study the city's park system and recommend a plan. John Charles Olmsted, the stepson of Frederick Law Olmsted, spent May 1903 in Portland.[12] The Olmsted Report, received in December, emphasized creation of a system of parks and linking parkways that would take advantage of natural scenery. It proposed a formal square for Union Station, squares along the downtown waterfront, and parks in places later known as Forest Park, Sellwood Park, Mount Tabor Park, Rocky Butte, and Ross Island, as well as Terwilliger Parkway, the 40 Mile Loop, and other connecting parkways.
