Assembly Hall (1889–1929), Foster Hall (1899–1951), Ross Hall (1891–1955), Gaithright Hall (1876–1933), and Mitchell Hall (1912–1972). The street was closed in 1971. Many of the original trees remain, but buildings, walk ways, and grassy areas were added in place of the street itself. The school began offering an expanded choice of degree programs at the same time that the state legislature and the United States Department of Agriculture established several services at Texas A&M. The college was unprepared for the ensuing population growth. For the next ten years, several hundred students lived in tents in a field in the middle of campus. In the late 1920s, following the discovery of oil on university lands, Texas A&M and the University of Texas negotiated a settlement for the division of the Permanent University Fund which enabled A&M to receive one-third of the revenue. This guaranteed wealth enabled A&M to grow and expand. World War II Enrollment soared after World War II as many former soldiers used the G.I. Bill to further their education. Again unprepared for the growth, between 1949 and 1953 Texas A&M used the former Bryan Air Force Base as an extension of the campus. An estimated 5,500 men lived, studied, ate, showered, and attended classes at the base, which became known as the Annex. Late 20th century The George Bush Presidential Library was established in 1997 on of land donated by Texas A&M at the western edge of the campus. This tenth presidential library was built between 1995 and 1997 and contains the presidential and vice-presidential papers of George H. W. Bush and the vice-presidential papers of Dan Quayle. In 1998, activists on campus (including Professor Patrick Slattery) suggested the statue of Lawrence Sullivan Ross should be removed on the basis that he was a member of the Ku Klux Klan. Instead, Slattery and others wanted to create a "diversity plaza", with a statue of Matthew Gaines, an African-American politician. The project was abandoned in the wake of the Aggie Bonfire tragedy, in 1999. The 2004 Campus Master Plan To address the rapid growth of the student body and faculty, Texas A&M created a Campus Master plan that provided guidelines on campus development. The plan created by the architectural firm Barnes Gromatzky Kosarek Architects with Michael Dennis & Associates, was completed in July 2004. The primary goals of the plan were to: reinforce campus identity and community, establish connectivity,
