April 30, 1789 - On the balcony of Federal Hall on Wall Street in New York City, George Washington was sworn in as the first President of the United States. Washington dressed for the occasion in an American-made dark brown suit with white silk stockings and silver shoe buckles; he also wore a steel-hilted sword. He was sworn in by Robert Livingston, Chancellor of New York, who after administering the oath shouted to the crowd below "Long live George Washington, President of the United States!"

May 1, 1931 - The Empire State Building was dedicated in New York City. The 102-story Art Deco skyscraper stood as the world's tallest building for more than 40 years, from its completion in 1931 until construction of the World Trade Center's North Tower was completed in 1972. The building was designed by William F. Lamb from the architectural firm Shreve, Lamb and Harmon, which produced the building drawings in just two weeks, using its earlier designs for the Reynolds Building in Winston-Salem, North Carolina. Every year the staff of the Empire State Building sends a Father's Day card to the staff at the Reynolds Building in Winston-Salem to pay homage to its role as predecessor.

May 1, 1991 - Rickey Henderson of the Oakland Athletics stole his 939th base, making him the all-time leader in stolen bases. However, his accomplishment was somewhat overshadowed later that evening when Nolan Ryan of the Texas Rangers, pitched his seventh career no-hitter, breaking his previous record of six. Henderson would go on to steal 1,406 bases in his career, 468 more stolen than his nearest competitor while Ryan not only holds the record for most no-hitters but also for career strikeouts with 5,714.
