April 30th in history:
The treaty authorizing the Louisiana Purchase was approved on April 30th, 1803. Exactly nine years later, on this date in 1812, Louisiana became the 18th state in the union.
The “Louisiana Purchase Exposition” marking the 100th anniversary of the purchase opened in St. Louis on April 30th, 1904. Better known as the St. Louis World’s Fair, it was the inspiration for the movie musical “Meet Me in St. Louis,” and it was said to be the place where Dr Pepper and the ice cream cone became popular.
April 30th also was the opening day for the 1939 New York World’s Fair.
The ’39 fair opened exactly 150 years after the day George Washington was sworn in as president in New York – April 30th, 1789.
