The Herbert Hoover Presidential Library and Museum is the presidential library and final resting place of Herbert Clark Hoover, the 31st President of the United States (1929 - 1933), located on the grounds of the Herbert Hoover National Historic Site in West Branch, Iowa. The library is one of thirteen presidential libraries run by the National Archives and Records Administration.In 1954, a group of Hoover's friends incorporated the Herbert Hoover Birthplace Foundation to raise money for the preservation of his birthplace and the area around it, and to plan for improvements to the site. One of their ideas was to build a small museum, and with Hoover's approval work began in the late 1950s. The architectural firm of Eggers and Higgins of New York drew the plans for the original building, a modest limestone structure of just over 4,000 square feet. While the museum at West Branch was still under construction, Hoover decided to expand it and to make it his Presidential Library.The Library-Museum was officially dedicated and opened to the public on August 10, 1962, Hoover's 88th birthday. The original Library-Museum building was expanded several times, with major additions being completed in 1964, 1971, 1974 and 1992. The architects for the 1964, 1971, and 1974 expansion projects were Wetherell, Harrison & Wagner Associates. The architects for the 1992 expansion were HNTB Corp. The building now totals 47,169 square feet.
