Prior to development, the land that became Palm Beach Gardens was primarily cattle ranches and pine forests, as well as swampland farther west. In 1959, wealthy landowner and insurance magnate John D. MacArthur announced plans to develop and build homes for 55,000 people. He chose the name Palm Beach Gardens after his initial choice, Palm Beach City, was denied by the Florida Legislature, because of the similarity of the name to the nearby Palm Beach. MacArthur planned to build a "garden city" so he altered the name slightly. The city was incorporated as a "paper town" (meaning that it existed only on paper) in 1959. The 1960 Census recorded that the city officially had a population of one, apparently a squatter whom MacArthur had allowed to stay on his property.
