May 31 marks the anniversary of the catastrophic South Fork Dam collapse in 1889, which devastated Johnstown, Pennsylvania, killing over 2,200 residents as 20 million tons of water surged through the town. This tragedy remains one of the deadliest disasters in U.S. history. Additionally, on this date in 1790, President George Washington enacted the first copyright law in the United States. The day is also remembered for other significant historical events, including the 1921 Tulsa race massacre, where white mobs attacked the affluent Black district of Greenwood, resulting in an estimated 300 deaths. In 1970, a powerful earthquake struck the Ancash region of Peru, claiming around 67,000 lives due to the subsequent landslide. The day also witnessed the revelation of 'Deep Throat's' identity in the Watergate scandal in 2005. Today's notable birthdays include actor Clint Eastwood, who turns 96, and football legend Joe Namath, who turns 83.
