This Day in History

United States

1787 | The first Federalist essay appears. Writing as “Publius,” Alexander Hamilton opened the newspaper campaign for ratification of the proposed U.S. Constitution in New York’s Independent Journal. The essay framed the choice as a test of whether Americans could establish government through deliberation rather than accident or force. Hamilton, James Madison and John Jay eventually produced 85 essays; opponents of ratification also argued vigorously in print.

1938 | Nylon is publicly introduced. DuPont formally announced nylon, a synthetic polyamide fiber, at a New York forum near the site of the coming World’s Fair. Research under chemist Wallace Carothers had helped make the new material possible, but nylon stockings were not yet widely available for purchase. The announcement anticipated a major change in textiles, consumer products and wartime manufacturing.

1954 | Disneyland premieres on television. Walt Disney’s weekly anthology program Disneyland debuted on ABC months before the Anaheim theme park opened.
