The inaugural ceremony took place on January 20, 1949. Truman took the
oath of office administered by Chief Justice of the United States Fred Vinson. Truman then delivered an address and departed with the parade. According to one analysis, the delayed arrival of members of Congress created a break in succession of Truman's terms as president: the
Twentieth Amendment to the United States Constitution, ratified in 1933, states that a president's term ends at noon on January 20 after the election. As some members of Congress arrived 10 minutes late, and took another 10 minutes to take their seats, Vice President
Alben W. Barkley was inaugurated at 12:23, technically serving as president for six minutes until Truman was inaugurated at 12:29. In the inaugural address, sometimes called the
Four Point speech, Truman discussed economic growth and opposition to Communism across the globe. This moment is often identified as the beginning of
development policy in relation to
Third World. Millions of people watched the inauguration, broadcast as a single live program that aired on every network. (Millions more listened on radio). Many schoolchildren watched from their classrooms. According to some calculations, the 1949 inauguration had more witnesses than all previous presidential inaugurations combined. Weather conditions for 12 noon at
Washington National Airport, located 3.1 miles from the ceremony, were: 39 °F (4 °C), wind 16 mph, and no precipitation. ==Demonstrations==
