April 8

April 8 is the 99th day of the year, and the American record for it runs from 1832 to 2024 — a span of 192 years. The entry that anchors it: American Civil War, 1864.

Through the nineteenth century the date gathered the tensions that would define the era. In 1832, Black Hawk War — around 300 United States 6th Infantry troops leave St. Louis, Missouri to fight the Sauk Native Americans. Then, in 1864, American Civil War — Late-arriving reinforcements helped Confederate forces rout the Union Army at the Battle of Mansfield.

In the decades after the Civil War, the date marked a country remaking itself. In 1895, in Pollock v. Farmers' Loan & Trust Co. the Supreme Court of the United States declares unapportioned income tax to be unconstitutional.

As the country moved into the modern age, the date accumulated new kinds of firsts. In 1911, American cartoonist Winsor McCay released the silent short film Little Nemo (featured), one of the earliest animated films. Then, in 1942, World War II — the United States Army Air Forces flew its first mission from India over the Hump (the eastern end of the Himalayas) to deliver materiel to China.

In the postwar decades the date belonged to a nation of enormous reach and unfinished arguments. In 1975, Voyageurs National Park is established by the U.S. Congress.

In living memory, the date has kept adding to the record. In 2010, U.S. President Barack Obama and Russian President Dmitry Medvedev sign the New START Treaty. Then, in 2024, Solar eclipse — a total solar eclipse takes place at the Moon's ascending node, visible across North America.

The date is also a birthday. Among the Americans born on April 8: Lewis Morris (1726), American judge and politician; David Rittenhouse (1732), American astronomer and mathematician; Elizabeth Bacon Custer (1842), American author and educator; Allen Butler Talcott (1867), American painter and educator; and Harvey Cushing (1869), American surgeon and academic.

April 8 is also a date of endings. Among the Americans who died on it: John Wise (1725), American minister; Elisha Otis (1861), American businessman, founded the Otis Elevator Company; Charles Griffes (1920), American pianist and composer; and Breece D'J Pancake (1979), American short story writer.

Taken together, the 8 entries on April 8 span 192 years of American life. A date is an arbitrary container, but what fills it is not arbitrary at all.
