April 12

April 12 is the 103rd day of the year, and the American record for it runs from 1776 to 1999 — a span of 223 years. The entry that anchors it: U.S. President Franklin D. Roosevelt dies in office, 1945.

The revolutionary generation left its own mark on the date. In 1776, American Revolution — the North Carolina Provincial Congress passed the Halifax Resolves, the first official action in the American colonies calling for independence from Great Britain.

The antebellum decades brought the date closer to the country’s central argument. In 1861, Confederate forces began a bombardment of Fort Sumter in the harbor of Charleston, South Carolina, starting the American Civil War. Three years on, in 1864, The Battle of Fort Pillow — Confederate forces kill most of the African American soldiers that surrendered at Fort Pillow, Tennessee. A year later, in 1865, American Civil War — Mobile, Alabama, falls to the Union Army.

The early twentieth century brought industry, air travel and war to the date. In 1934, the U.S. Auto-Lite strike begins, culminating in a five-day melee between Ohio National Guard troops and 6,000 strikers and picketers. Then, in 1945, U.S. President Franklin D. Roosevelt dies in office; Vice President Harry S. Truman succeeds him.

The most recent entries fall within living memory. In 1990, Jim Gary's "Twentieth Century Dinosaurs" exhibition opens at the Smithsonian Institution National Museum of Natural History in Washington, D.C. He is the only sculptor ever invited to present a solo exhibition there. Nine years on, in 1999, United States President Bill Clinton is cited for contempt of court for giving "intentionally false statements" in a civil lawsuit; he is later fined and disbarred.

The date is also a birthday. Among the Americans born on April 12: Lyman Hall (1724), American physician, clergyman, and politician, 16th Governor of Georgia; Henry Clay (1777), American lawyer and politician, 9th United States Secretary of State; George N. Briggs (1796), American lawyer and politician, 19th Governor of Massachusetts; William B. Bankhead (1874), American lawyer and politician, 47th Speaker of the United States House of Representatives; and Addie Joss (1880), American baseball player and journalist.

April 12 is also a date of endings. Among the Americans who died on it: Ambrose Dixon (1687), English-American soldier; Adoniram Judson (1850), American lexicographer and missionary; William M. Tweed (1878), American lawyer and politician; and Clara Barton (1912), American nurse and humanitarian, founded the American Red Cross.

The date carries formal observance as well — Commemoration of first human in space by Yuri Gagarin: — International Day of Human Space Flight. What holds these 8 entries together is nothing more than the calendar, and nothing less. 223 years separate the earliest from the latest, and each was once simply the present day.
