May 25

May 25 is the 146th day of the year, and the American record for it runs from 1782 to 2020 — a span of 238 years. The entry that anchors it: Apollo program, 1961.

In the years around independence, the date turns political. In 1782, American Revolutionary War — US Colonel William Crawford began a failed expedition to destroy British-allied American Indian towns along the Sandusky River in the Ohio Country. Five years on, in 1787, the Constitutional Convention met in Philadelphia with the intention of revising the Articles of Confederation of the United States.

The postwar entries show a nation both expanding and contesting itself. In 1955, in the United States, a night-time F5 tornado strikes the small city of Udall, Kansas as part of a larger outbreak across the Great Plains, killing 80 and injuring 273. It is the deadliest tornado ever to occur in the state and the 23rd deadliest in the U.S. Six years on, in 1961, Apollo program — U.S. President John F. Kennedy announces, before a special joint session of the U.S. Congress, that the United States "should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth." A year later, in 1962, the Baltimore Steam Packet Company, the last overnight steamboat service in the United States, went out of business. Then, in 1979, during takeoff from O'Hare International Airport in Chicago, an engine detached from American Airlines Flight 191, causing a crash that killed 273 people in the deadliest aviation accident in United States history.

Closer to the present, the date is still accumulating. In 1999, the United States House of Representatives releases the Cox Report which details China's nuclear espionage against the U.S. over the prior two decades. Then, in 2020, George Floyd, a black American man, was murdered during an arrest by a white police officer in Minneapolis, sparking protests in the U.S. and other countries.

The date is also a birthday. Among the Americans born on May 25: Samuel Ward (1725), American politician, 31st and 33rd Governor of the Colony of Rhode Island and Providence Plantations; Philip P. Barbour (1783), American farmer and politician, 12th Speaker of the United States House of Representatives; Ralph Waldo Emerson (1803), American poet and philosopher; William Muldoon (1852), American wrestler and trainer; and James McKeen Cattell (1860), American psychologist and academic.

May 25 is also a date of endings. Among the Americans who died on it: Austin Lane Crothers (1912), American educator and politician, 46th Governor of Maryland; Eliza Pollock (1919), American archer; Madam C. J. Walker (1919), American businesswoman and philanthropist, founded the Madame C.J. Walker Manufacturing Company; and Payne Whitney (1927), American businessman and philanthropist.

The date carries formal observance as well — First National Government / National Day (Argentina); International Missing Children's Day and its related observances: — National Missing Children's Day (United States),; and National Tap Dance Day (United States). May 25 carries 8 entries spread across 238 years. None of the people in them knew they were sharing a date; that is a pattern only visible looking back.
