landscape, and wanted to work with someone who was equally passionate. Vaux accepted the opportunity and subsequently moved to the United States. Vaux worked with Downing for two years and became a firm partner. Together, they designed many projects such as the White House grounds and the Smithsonian Institution in Washington, D.C. Vaux's work on the Smithsonian inspired him to write an article in 1852 for The Horticulturalist, of which Downing was the editor. In his publication, he argued that the government should recognize and support the arts. Shortly afterward, Downing died in a steamboat accident. Vaux & Withers After Downing's death, Vaux gained control of the firm. As a partner, he hired Frederick Clarke Withers, who was already working at the company. In two separate periods of partnership, interrupted by the Civil War, their projects included multiple houses in Newburgh, the Hudson River State Hospital, and the Jefferson Market Courthouse. U.S. citizenship, affiliations, and publishing In 1856, he gained U.S. citizenship and became identified with New York City's artistic community, “the guild,” joining the National Academy of Design, as well as the Century Club. In 1857, he became one of the founding members of the American Institute of Architects. Also in 1857, Vaux published Villas and Cottages, which was an influential pattern book that determined the standards for “Victorian Gothic” architecture. These particular writings revealed his acknowledgment and tribute to Ruskin and Ralph Waldo Emerson, as well as to his former partner Downing. These people, among others, influenced him intellectually and in his design path. Collaboration with Olmsted In 1857, Vaux recruited Frederick Law Olmsted, who had never before designed a landscape plan, to help with the Greensward Plan, which would become New York City's Central Park. They obtained the commission through the Greensward Plan, an excellent presentation that drew upon Vaux's talents in landscape drawing to include before-and-after sketches of the site. Together, they fought many political battles to make sure their original design remained intact and was carried out. All of the built features of Central Park were of his design; Bethesda Terrace is a good example. In 1865, Vaux and Olmsted founded Olmsted, Vaux and Co., which went on to design Prospect Park and Fort Greene Park in Brooklyn, and Morningside Park in Manhattan. In Chicago, they planned one of the first suburbs for the Riverside Improvement Company in 1868. They also were commissioned to design
