February 13 in History

The most famous scientist in Europe traveled to Rome in February 1633 knowing he would be put on trial for telling the truth. Galileo Galilei, 69 years old and in failing health, arrived to face the Roman Inquisition on charges of heresy for advocating the Copernican model — the idea that the Earth revolves around the Sun. The trial that followed became the defining collision between scientific evidence and institutional authority. Galileo had been warned once before. In 1616, Cardinal Robert Bellarmine informed him that Copernicanism could be discussed as a mathematical hypothesis but not defended as physical truth. Galileo largely complied for sixteen years. Then, in 1632, he published Dialogue Concerning the Two Chief World Systems, a devastating demolition of geocentric astronomy thinly disguised as a balanced debate. The character defending the Earth-centered view was named Simplicio — and readers recognized him as a stand-in for Pope Urban VIII, who had previously been Galileo’s patron and friend. Urban was furious. The Inquisition summoned Galileo to Rome despite his pleas of illness and old age. The trial, conducted between April and June 1633, focused on whether Galileo had violated the 1616 injunction. The scientific merits of heliocentrism were never seriously debated. The outcome was predetermined: Galileo was found "vehemently suspect of heresy," forced to recant his views on his knees, and sentenced to house arrest for the remainder of his life. The legend that Galileo muttered "Eppur si muove" ("And yet it moves") after his recantation is almost certainly apocryphal. What is documented is that he spent his final nine years under house arrest at his villa in Arcetri, where he went blind but continued working, producing his finest work on physics and mechanics. He died in 1642. The Catholic Church did not formally acknowledge its error until 1992. Galileo’s trial did not stop the scientific revolution — it merely proved that truth does not require the permission of authority to remain true.

A fireball rose over the Algerian Sahara at 7:04 AM on February 13, 1960, and France became the fourth nation to detonate a nuclear weapon. Gerboise Bleue — Blue Jerboa, named after a desert rodent — exploded with a yield of 70 kilotons, more than three times the power of the Hiroshima bomb and the largest first test by any nuclear power. Charles de Gaulle had his bomb, and France had announced itself as a global force that answered to no one. France’s nuclear program began in 1954, driven by twin humiliations: the loss of Indochina at Dien Bien Phu and the Suez Crisis of 1956, where American and Soviet pressure forced France and Britain to withdraw from Egypt. De Gaulle, who returned to power in 1958, was determined that France would never again depend on allies for its security. The bomb was the centerpiece of his force de frappe — an independent nuclear deterrent that would give France a permanent seat at any table where the world’s fate was discussed. The test site at Reggane, deep in the Sahara, was chosen for its remoteness, but it was not uninhabited. Nomadic Tuareg communities lived in the region, and Algerian workers were employed at the base. French authorities evacuated some nearby populations but the radius was insufficient. Subsequent investigations found elevated rates of cancer and genetic abnormalities among those exposed to fallout from this and the three atmospheric tests that followed. The international reaction was overwhelmingly negative. African nations condemned France for testing nuclear weapons on their continent. The Soviet Union and United States, despite their own massive arsenals, denounced the test. Japan protested formally. De Gaulle was unmoved, declaring that France was now "stronger and prouder." France conducted a total of 210 nuclear tests over the next 36 years, developing a complete nuclear triad, and remains one of five recognized nuclear weapons states — a status purchased in the Algerian desert on a February morning.

A device weighing five kilograms changed the way the human race tells stories. Auguste and Louis Lumiere patented the Cinematographe on February 13, 1895, a machine that could record, develop, and project moving images — replacing Thomas Edison’s bulky, single-viewer Kinetoscope with something that could fill a room with an audience watching the same flickering images together. Cinema was born not as a technology but as a shared experience. The Lumiere brothers were not dreamers. They ran their father’s photographic plate factory in Lyon, the largest in Europe, and approached moving pictures as an engineering problem. Edison’s Kinetoscope, introduced in 1893, required viewers to peer into a box one at a time — commercially limited and socially isolating. The Lumieres designed a hand-cranked machine that served as camera, printer, and projector in one, using 35mm film stock at 16 frames per second. The intermittent mechanism that stopped each frame briefly behind the lens was adapted from the mechanism of a sewing machine. Their first public screening took place on December 28, 1895, at the Salon Indien du Grand Cafe in Paris. Thirty-three people paid one franc each to watch ten short films, each about 50 seconds long. The program included workers leaving the Lumiere factory, a baby being fed, and a train arriving at a station. The audience reportedly flinched as the train appeared to rush toward them. Word spread immediately, and within weeks the screenings were drawing 2,000 people a day. The Lumieres sent cameramen around the world to film and exhibit, creating both the first international film distribution network and the first documentary footage of dozens of countries. Yet they famously dismissed their own invention. "The cinema is an invention without a future," Louis Lumiere reportedly said, viewing it as a scientific curiosity rather than an entertainment medium. The brothers who believed cinema had no future had inadvertently created the most influential art form of the twentieth century.

The soldiers had been guests for twelve days. They had eaten MacDonald food, slept in MacDonald homes, warmed themselves by MacDonald fires. Then, at five o’clock on the morning of February 13, 1692, Captain Robert Campbell of Glenlyon and his men rose in the darkness and began killing their hosts. The Massacre of Glencoe killed 38 members of the MacDonald clan, though dozens more — including women, children, and elderly — died of exposure fleeing into the Highland winter. The massacre had its roots in politics, not clan rivalry. William III, the Dutch Protestant who had taken the English and Scottish thrones from the Catholic James VII in 1688, demanded that all Highland clan chiefs swear an oath of allegiance by January 1, 1692. Most complied, however reluctantly. Alasdair MacIain, chief of the Glencoe MacDonalds, tried to swear the oath but was delayed by bureaucratic obstacles — he went to the wrong official first and did not reach the sheriff at Inveraray until January 6, five days late. The government, particularly Secretary of State John Dalrymple, saw an opportunity. Dalrymple wanted to make an example of a clan to terrorize the Highlands into submission, and the MacDonalds’ late oath gave him a legal pretext. He obtained orders from William III authorizing the extirpation of the Glencoe MacDonalds, then sent 120 soldiers under Campbell of Glenlyon — whose niece was married to one of MacIain’s sons — to be quartered among the MacDonalds under the guise of collecting taxes. The killing began before dawn. MacIain was shot in his bed. His wife was stripped of her clothes and her rings bitten from her fingers. Soldiers bayoneted men, women, and children, though many escaped into the glen because the planned blocking forces arrived late due to a blizzard. About 300 to 400 survivors fled into the mountains in freezing conditions, and an unknown number perished from exposure. The massacre violated the most sacred law of Highland culture — the duty of hospitality — and the betrayal of trust ensured that Glencoe would be remembered with particular horror for centuries after far bloodier events were forgotten.
