July 30

July 30 is the 212th day of the year, and the American record for it runs from 1863 to 2020 — a span of 157 years. The entry that anchors it: Watergate scandal, 1974.

By the middle of the nineteenth century the date carries heavier freight. In 1863, American Indian Wars — representatives of the United States and tribal leaders including Chief Pocatello (of the Shoshone) sign the Treaty of Box Elder.

In the postwar nineteenth century the date tracks a nation rebuilding. In 1866, Armed Confederate veterans in New Orleans riot against a meeting of Radical Republicans, killing 48 people and injuring another 100.

In the first half of the twentieth century the date turns technological. In 1916, World War I — German agents sabotaged U.S.-made munitions in New York Harbor that were to be supplied to the Allies.

The postwar entries show a nation both expanding and contesting itself. In 1956, a joint resolution of the U.S. Congress is signed by President Dwight D. Eisenhower, authorizing In God We Trust as the U.S. national motto. Nine years on, in 1965, U.S. president Lyndon B. Johnson signs the Social Security Act of 1965 into law, establishing Medicare and Medicaid. Four years on, in 1969, Vietnam War — U.S. president Richard Nixon makes an unscheduled visit to South Vietnam and meets with President Nguyễn Văn Thiệu and U.S. military commanders. Five years on, in 1974, Watergate scandal — U.S. President Richard Nixon releases subpoenaed White House recordings after being ordered to do so by the Supreme Court of the United States.

Closer to the present, the date is still accumulating. In 2020, NASA's Mars 2020 mission is launched on an Atlas V rocket from Cape Canaveral Air Force Station.

The date is also a birthday. Among the Americans born on July 30: Charles Chiniquy (1809), Canadian-American priest and theologian; George Lemuel Woods (1832), American lawyer, judge, and politician, 3rd Governor of Oregon; Thorstein Veblen (1857), American economist and sociologist; Henry Ford (1863), American engineer and businessman, founded the Ford Motor Company; and Smedley Butler (1881), American general, Medal of Honor recipient.

July 30 is also a date of endings. Among the Americans who died on it: George Pickett (1875), American general; Joyce Kilmer (1918), American soldier, journalist, and poet; George Szell (1970), Hungarian-American conductor and composer; and James Blish (1975), American author and critic.

The date carries formal observance as well — International Day of Friendship (international), and its related observances: — Día del Amigo (Paraguay). July 30 carries 8 entries spread across 157 years. None of the people in them knew they were sharing a date; that is a pattern only visible looking back.
