The first televised White House address is given by U.S. President Harry S. Truman.

Harry S. Truman (May 8, 1884 December 26, 1972) was the 33rd president of the United States, serving from 1945 to 1953. A member of the Democratic Party, he previously served as the 34th vice president from January to April 1945 under Franklin Roosevelt and as a United States Senator from Missouri from 1935 to January 1945. Having assumed the presidency after Roosevelt's death, Truman implemented the Marshall Plan to rebuild the economy of Western Europe and established both the Truman Doctrine and NATO to contain the expansion of communism. He proposed numerous liberal domestic reforms, but few were enacted by the Conservative Coalition which dominated the Congress.

Truman grew up in Independence, Missouri, and during the First World War fought in France as a captain in the Field Artillery. Returning home, he opened a haberdashery in Kansas City, Missouri, and was elected as a judge of Jackson County in 1922. Truman was elected to the United States Senate from Missouri in 1934. In 19401944 he gained national prominence as chairman of the Truman Committee, which was aimed at reducing waste and inefficiency in wartime contracts. Only after assuming the presidency was he informed about the atomic bomb. Truman authorized the first and only use of nuclear weapons in war against Hiroshima and Nagasaki in Japan. Truman's administration engaged in an internationalist foreign policy by working closely with British Prime Minister Clement Attlee. Truman staunchly denounced isolationism. He energized the New Deal coalition during the 1948 presidential election and won a surprise victory against Republican Thomas E. Dewey that secured his own presidential term.

Truman presided over the onset of the Cold War in 1947. He oversaw the Berlin Airlift and Marshall Plan in 1948. With the involvement of the US in the Korean War of 19501953, South Korea repelled the invasion by North Korea. Domestically, the postwar economic challenges such as strikes and inflation created a mixed reaction over the effectiveness of his administration. In 1948, he proposed Congress pass comprehensive civil rights legislation. Congress refused, so in 1948 Truman issued Executive Order 9980 and Executive Order 9981 which desegregated the armed forces and federal agencies.

Corruption in the Truman administration became a central campaign issue in the 1952 presidential election. He was eligible for reelection in 1952, but with weak polls he decided not to run. Republican Dwight D. Eisenhower attacked Truman's record and won easily. Truman went into a retirement marked by the founding of his presidential library and the publication of his memoirs. It was long thought that his retirement years were financially difficult for Truman, resulting in Congress establishing a pension for former presidents, but evidence eventually emerged that he amassed considerable wealth, some of it while still president. When he left office, Truman's administration was heavily criticized, though critical reassessment of his presidency has improved his reputation among historians and the general population.

The White House is the official residence and workplace of the president of the United States. It is located at 1600 Pennsylvania Avenue NW in Washington, D.C., and has been the residence of every U.S. president since John Adams in 1800. The term "White House" is often used as a metonym for the president and his advisers.

The residence was designed by Irish-born architect James Hoban in the neoclassical style. Hoban modelled the building on Leinster House in Dublin, a building which today houses the Oireachtas, the Irish legislature. Construction took place between 1792 and 1800, using Aquia Creek sandstone painted white. When Thomas Jefferson moved into the house in 1801, he (with architect Benjamin Henry Latrobe) added low colonnades on each wing that concealed stables and storage. In 1814, during the War of 1812, the mansion was set ablaze by the British Army in the Burning of Washington, destroying the interior and charring much of the exterior. Reconstruction began almost immediately, and President James Monroe moved into the partially reconstructed Executive Residence in October 1817. Exterior construction continued with the addition of the semi-circular South portico in 1824 and the North portico in 1829.

Because of crowding within the executive mansion itself, President Theodore Roosevelt had all work offices relocated to the newly constructed West Wing in 1901. Eight years later, in 1909, President William Howard Taft expanded the West Wing and created the first Oval Office, which was eventually moved as the section was expanded. In the main mansion (Executive Residence), the third-floor attic was converted to living quarters in 1927 by augmenting the existing hip roof with long shed dormers. A newly constructed East Wing was used as a reception area for social events; Jefferson's colonnades connected the new wings. The East Wing alterations were completed in 1946, creating additional office space. By 1948, the residence's load-bearing exterior walls and internal wood beams were found to be close to failure. Under Harry S. Truman, the interior rooms were completely dismantled and a new internal load-bearing steel frame was constructed inside the walls. On the exterior, the Truman Balcony was added. Once the structural work was completed, the interior rooms were rebuilt.

The modern-day White House complex includes the Executive Residence, the West Wing, the East Wing, the Eisenhower Executive Office Building (the former State Department, which now houses offices for the president's staff and the vice president) and Blair House, a guest residence. The Executive Residence is made up of six stories: the Ground Floor, State Floor, Second Floor, and Third Floor, as well as a two-story basement. The property is a National Heritage Site owned by the National Park Service and is part of the President's Park. In 2007, it was ranked second on the American Institute of Architects list of "America's Favorite Architecture".
