In 1947, the National Council for Historic Sites and Buildings started raising awareness of the need for a National Trust and held the nation's first Preservation Conference in Washington DC. The National Trust for Historic Preservation was then created in 1949 through legislation signed by President Harry S. Truman. The National Trust is a private, non-profit membership organization staffing people at their Washington DC headquarters, six regional offices, and 29 historic sites to work with over 200,000 members as well as preservation groups in all 50 states to educate people about, preserve, and maintain historic buildings and sites in the United States. "Alternating Currents" was the theme chosen for the 2011 National Preservation Conference, held October 19-22 in Buffalo, New York.
