History of Constitution Day (United States)

Iowa schools first recognized Constitution Day in 1911. In 1917, the Sons of the American Revolution formed a committee to promote Constitution Day. The committee would include members such as Calvin Coolidge, John D. Rockefeller, and General John Pershing.
In 1939, William Randolph Hearst advocated, through his chain of daily newspapers, the creation of a holiday to celebrate citizenship. In 1940, Congress designated the third Sunday in May as I am an American Day. By 1949, governors of all 48 states had issued Constitution Day proclamations. On February 29, 1952, Congress moved that observation to September 17th and renamed it "Citizenship Day".
Louisville, Ohio, calls itself Constitution Town and credits one of its own for getting the holiday national recognition. In 1952, resident Olga T. Weber petitioned municipal officials to establish Constitution Day, in honor of the ratification of the US Constitution in 1789. Mayor Gerald A. Romary proclaimed September 17, 1952, as Constitution Day in the city. The following April, Weber requested that the Ohio General Assembly proclaim September 17 as state-wide Constitution Day. Her request was signed into law by Governor Frank J. Lausche. In August 1953, she took her case to the United States Senate, which passed a resolution designating September 17-23 as Constitution Week. The Senate and House approved her request and it was signed into law by President Dwight D. Eisenhower. On April 15, 1957, the City Council of Louisville declared the city Constitution Town. The Ohio State Archaeological and Historical Society later donated four historical markers, located at the four main entrances to the city, explaining Louisville's role as originator of Constitution Day.
The Space Shuttle Enterprise was originally planned to be named Constitution. However, even after the name was changed, the Shuttle was dedicated on Constitution Day 1976.
