November 22 brings together moments when a signal, a leader, or a work of art changed how people understood the world around them. In 1890, Charles de Gaulle was born; decades later, he would lead the Free French Forces and help shape the Fifth Republic. In 1906, an international convention adopted SOS as a standard Morse code distress signal, giving ships a shared call for help. And in 1928, Maurice Ravel’s Boléro premiered in Paris, its insistent melody building through repetition and rising volume.
The day’s events also show how sharply history can turn. De Gaulle’s birth points toward leadership forged in crisis, while the adoption of SOS reflects the value of clear communication when lives are at stake. On November 22, 1963, President John F. Kennedy was assassinated in Dallas, and Lyndon B. Johnson was sworn in later that day. In late November, as the year approaches its close, reflection comes naturally; this list offers a reminder that history’s patterns include both gradual change and sudden rupture. A convention can standardize a signal, a composition can make repetition feel new, and a single day can mark a nation’s grief and a transfer of power.
