His visitors included incumbent Presidents Eisenhower, Kennedy, Johnson, and Nixon, former President Hoover, Jack Benny, Ginger Rogers, Robert F. Kennedy, Thomas Hart Benton, and Dean Acheson. When Truman left the White House in 1953, he established an office in Room 1107 of the Federal Reserve Bank of Kansas City at 925 Grand Avenue. When the library opened in 1957, he transferred his office to the facility and often worked there five or six days a week.) In the office, he wrote articles, letters, and his book "Mr. Citizen". In 2007, the Truman Library Institute announced a $1.6 million preservation and restoration of his working office to preserve the artifacts it contains and allow for easier public viewing. The three-stage project completed in 2009 and features an enclosed limestone pavilion for better access and viewing and an updated climate control system. The office appears today just as it did when Harry Truman died on December 26, 1972. Long a favorite of museum visitors, the office was viewed through a window from the library's courtyard. The pavilion will also allow for an interpretive exhibit describing the office. Funeral services for Truman were held in the Library auditorium and burial was in the courtyard. His wife, Bess Truman, was buried at his side in 1982. Their daughter, Margaret Truman Daniel, was a longtime member of the Truman Library Institute's board of directors. After her death in January 2008, Margaret's cremated remains and those of her late husband, Clifton Daniel (who died in 2000), were also interred in the Library's courtyard. The president's grandson, Clifton Truman Daniel, is currently honorary co-chair of the institute's board of directors. Two floors of exhibits show his life and presidency through photographs, documents, artifacts, memorabilia, film clips and a film about Truman's life. The library's replica of the Oval Office is a feature that has been copied by the Johnson, Ford, Carter, Reagan, George H. W. Bush, Clinton, and George W. Bush libraries. In an educational program called "The White House Decision Center", school students take on the roles of President Truman and his advisors facing real-life historical decisions in a recreation of the West Wing of the White House. The mural "Independence and the Opening of the West" by Thomas Hart Benton adorns the walls of the lobby entrance. The mural, completed in 1961, was painted on site by Benton over a three-year span. Visitors after 1972 include incumbent Presidents Ford, Carter, and Clinton and Presidential Nominees John Kerry and John McCain.
