Alfred Lacroix arrived on Martinique six weeks after the 1902 eruption of Mount Pelée had killed thirty thousand people. He spent the next four years on the island reconstructing exactly what had happened. The science of volcanology, more or less, is what he found.
Read the story →Amelia Earhart and her navigator Fred Noonan disappeared on 2 July 1937 between Lae, Papua New Guinea, and Howland Island. The Lockheed Electra was on the final third of a planned round-the-world equatorial circumnavigation. The largest naval search in US history at that point covered approximately 250,000 square miles but found nothing. The fate of the aircraft and its two occupants remains formally unresolved.
Read the story →Anna Anderson was pulled from a Berlin canal in February 1920 and claimed to be Grand Duchess Anastasia Nikolaevna of Russia, surviving daughter of Tsar Nicholas II. She maintained the claim through forty-five years of litigation and three biographies. DNA analysis in 1994 — three years after her 1984 cremation — identified her as the Polish factory worker Franziska Schanzkowska.
Read the story →The Ottoman government deported the Armenian population of eastern Anatolia eastward into the Syrian desert from April 1915. Approximately one million Armenians died in the marches, the concentration camps along the Euphrates, or in direct massacres. The killing was organised by the Ottoman Special Organisation under the cabinet of the Committee of Union and Progress. The Turkish Republic has not, as of 2026, formally acknowledged the killings as genocide.
Read the story →In 1943, in British-ruled Bengal, around three million people died of starvation and famine disease while rice remained available for those who could pay. War policy — the fall of Burma, 'denial' seizures of boats and rice, prioritisation of Calcutta's war industries, and London's repeated refusal of shipping for relief — turned price shock into mass death. Amartya Sen's analysis of it reshaped how famine itself is understood.
Read the story →At approximately 12:30 on 15 January 1919 a steel tank holding 2.3 million gallons of molasses ruptured in Boston's North End. The wave — estimated at 25 feet high, moving at 35 mph — killed 21 people, injured 150, and levelled buildings along Commercial Street.
Read the story →Captain Charles de Guillebon was the master of the French Liberty ship *Grandcamp* when fire broke out in its hold of 2,300 tons of ammonium nitrate at Texas City on 16 April 1947. He refused to flood the hold for fear of losing the cargo. The ship blew up at 9:12 AM. Everyone aboard died.
Read the story →The Crystal Palace housed the Great Exhibition of 1851, was moved to a south London hill, and stood there for eighty-five years. On the night of 30 November 1936 it caught fire and burned to the ground in a single evening. Two hundred thousand people watched.
Read the story →In February 1959 nine experienced Soviet ski-hikers died on the slope of Kholat Syakhl in the northern Urals. Their tent was found cut open from the inside; the bodies lay up to 1.5 km away, some barefoot in the snow, some with severe internal injuries. Sixty years of theories followed. The modern scientific verdict is a slab avalanche.
Read the story →Pittsburgh industrialist and amateur golf champion Eben Byers began drinking Radithor — certified radium dissolved in water — in 1927, at up to three bottles a day. By 1931 his bones were disintegrating and his jaw had been surgically removed. His death in March 1932 killed the radioactive patent-medicine industry, under the Wall Street Journal's immortal headline.
Read the story →President Woodrow Wilson suffered a major stroke on 2 October 1919. His wife Edith concealed the severity for the remaining seventeen months of his term, controlling all access to him and deciding which papers reached his desk. Vice President Marshall was never informed. Historians have called it the longest period of executive concealment in American history.
Read the story →In November 1932 the Australian military sent Major G.P.W. Meredith with two Lewis machine guns and 10,000 rounds to cull some 20,000 emus destroying wheat crops in Western Australia. After a month, the emus were winning and the operation was withdrawn.
Read the story →Six members of the Young Bosnia movement attempted to assassinate the Austro-Hungarian heir Archduke Franz Ferdinand in Sarajevo on the morning of 28 June 1914. The first attempt — a bomb thrown by Nedeljko Čabrinović — failed. The second — two pistol shots by Gavrilo Princip — killed the Archduke and his wife Sophie. Austria-Hungary declared war on Serbia within a month. The First World War followed.
Read the story →Franz Reichelt, an Austrian-born Parisian tailor, designed a wearable parachute suit and obtained permission to test it from the Eiffel Tower — with a dummy. On the morning of 4 February 1912, before Pathé news cameras, he jumped himself. The suit failed and he fell 57 metres to his death.
Read the story →The PS General Slocum caught fire in the East River off East 90th Street at approximately 10:00 a.m. on 15 June 1904. About 1,300 mostly German-American passengers from the St Mark's Lutheran Church annual Sunday-school picnic were aboard. The fire hoses were rotted, the life jackets were filled with cork dust packed with iron weights to meet the legal weight requirement, and 1,021 people died — most of them women and children.
Read the story →The Dow Jones Industrial Average fell 12.8 percent on Black Monday 28 October 1929 and 11.7 percent on Black Tuesday 29 October 1929. The Crash initiated a global Great Depression that bottomed in 1933 with US unemployment at approximately 25 percent and approximately 9,000 US banks failed. Industrial production took a decade to return to 1929 levels.
Read the story →At 11:58 on 1 September 1923, two minutes before noon, a magnitude 7.9 earthquake struck the Tokyo-Yokohama region as the city's lunch fires were lit. Firestorms did most of the killing — including some 38,000 people incinerated by a fire whirl at a single open square. Around 105,000 died; in the chaos, mobs massacred thousands of Koreans.
Read the story →The German Condor Legion's bombers attacked the small Basque town of Guernica in northern Spain on the afternoon of 26 April 1937 — a market day. The attack killed approximately 250-300 civilians and destroyed about 75 percent of the buildings. Pablo Picasso's monumental painting Guernica, completed two months later, became the canonical 20th-century anti-war image.
Read the story →From 5 to 9 December 1952 a windless anticyclone trapped London's coal smoke at street level. Visibility fell to arm's length, transport stopped, and cattle died at Smithfield. The official count was around 4,000 deaths; modern analyses put the toll at 10,000-12,000. It produced the Clean Air Act of 1956.
Read the story →On 6 December 1917, Vince Coleman had ninety seconds to warn the incoming trains. He used them, and then he was gone.
Read the story →Astronomers announced that on 18-19 May 1910 the Earth would pass through the tail of Halley's Comet — and that the tail contained cyanogen, a poison. Amplified by newspapers and a famous astronomer's speculation, the news spawned sealed rooms, comet pills, and gas masks. Mark Twain, born under the comet in 1835, died as it returned — as he had predicted.
Read the story →After the Herero rose against German colonial rule in 1904, General Lothar von Trotha issued a written extermination order and drove the people into the Omaheke desert; the Nama who rose next were broken in concentration camps like Shark Island. Some 65,000-80,000 Herero and 10,000 Nama died — the first genocide of the twentieth century, formally acknowledged by Germany in 2021.
Read the story →The German hydrogen airship LZ-129 Hindenburg caught fire on its final mooring approach at Lakehurst Naval Air Station, New Jersey, at 7:25 p.m. on 6 May 1937. The 245-metre airship burned to the ground in approximately 37 seconds. 36 of 97 people aboard died. The disaster ended commercial passenger airship aviation. Radio broadcaster Herbert Morrison's live recording — "oh, the humanity" — became the first major audio news broadcast in history.
Read the story →Five weeks after opening, Chicago's Iroquois Theatre — advertised as "absolutely fireproof" — burned during a matinee packed with women and children. Locked gates, inward-opening doors, and unfinished fire equipment killed 602 people in about twenty minutes, the deadliest single-building fire in US history.
Read the story →Nazi SA stormtroopers and civilians attacked Jewish synagogues, businesses, and homes across Germany and Austria on the night of 9-10 November 1938. 267 synagogues were burned. About 7,500 Jewish businesses were destroyed. About 91 Jews were killed and 30,000 arrested. The German Jewish community was forced to pay a one-billion-mark fine for the damage.
Read the story →Lake Cheko is a 500-metre-wide elliptical lake about 8 km northwest of the Tunguska blast epicentre. In 2007 an Italian research team proposed that the lake is the impact crater of a small unfragmented portion of the 1908 Tunguska body. The interpretation is substantially contested.
Read the story →Leonid Kulik led the first scientific expedition to the Tunguska blast site in 1927, returned four more times in the following thirteen years, and was preparing a sixth expedition when Germany invaded the Soviet Union. He volunteered for the People's Militia in 1941, was captured at Vyazma in October, and died of typhus in a Spas-Demensk POW camp in April 1942.
Read the story →The Cunard liner RMS Lusitania was torpedoed by the German submarine U-20 approximately 18 km off the southern Irish coast at 2:10 p.m. on 7 May 1915. She sank in 18 minutes. 1,198 of 1,959 aboard died, including 128 American citizens. The sinking shifted American public opinion against Germany and contributed to the eventual 1917 American entry into the First World War.
Read the story →Madeleine Lévy was the granddaughter of Alfred Dreyfus. She worked with the French Resistance, was arrested by the Lyon Gestapo in November 1943, was deported from Drancy to Auschwitz, and died of typhus there in January 1944. She was 25.
Read the story →Approximately 86,000 Chinese Communist soldiers and political workers broke out of the Nationalist encirclement of the Jiangxi Soviet on 16 October 1934 and began a 370-day, approximately 9,000-kilometre retreat across southern and western China to the Shaanxi base area. Approximately 8,000 reached Yan'an in October 1935. The march established Mao Zedong's leadership of the Chinese Communist Party.
Read the story →Margaretha Geertruida Zelle — performing as Mata Hari — was a 41-year-old Dutch exotic dancer convicted of espionage for Germany by a French court martial in July 1917 and executed by firing squad at Vincennes on 15 October 1917. The post-war access to the French and German intelligence archives substantially weakens the original espionage case against her.
Read the story →Douglas Mawson and two companions were 480 km from base on the Australasian Antarctic Expedition when one fell into a crevasse on 14 December 1912 with the dogs and most of the supplies. The second died of probable hypervitaminosis A on 8 January 1913. Mawson walked back alone for thirty days. By the time he reached base on 8 February 1913, the soles of his feet had detached and he had eaten his remaining sled dogs.
Read the story →From 1932 the Chisso Corporation discharged methylmercury into Minamata Bay, Japan. The neurological disease it caused was officially identified on 1 May 1956; Chisso's own physician proved the cause by 1959 and was silenced. The dumping continued until 1968. Thousands were certified as victims; the true number is far higher.
Read the story →On 8 May 1902 a volcano on Martinique destroyed a city of thirty thousand. Two men lived to tell about it. One was in a dungeon.
Read the story →Britain, France, Italy, and Germany signed the Munich Agreement at 1:30 a.m. on 30 September 1938. Czechoslovakia was forced to cede the German-speaking Sudetenland border regions.

Read the story →Every December since 1947 the City of Oslo has felled a substantial Norway spruce in the Nordmarka forest north of the city and sent it to London. It stands in Trafalgar Square through the Christmas season. The tree is a continuing thank-you for British support of the Norwegian government-in-exile during the Second World War.
Read the story →Bolshevik forces seized the Petrograd Winter Palace on the night of 7-8 November 1917 (25-26 October Old Style). The Provisional Government's cabinet was arrested in the Malachite Room. Lenin became chairman of the new Council of People's Commissars the next morning. The Russian Revolution had moved from its February-March 1917 democratic phase to its Bolshevik authoritarian phase in 8 months.
Read the story →353 Imperial Japanese aircraft attacked the US Pacific Fleet at Pearl Harbor, Hawaii, on the morning of Sunday 7 December 1941. The attack sank or damaged 19 American warships and killed 2,403 Americans. The United States declared war on Japan the next day. Germany and Italy declared war on the United States on 11 December. The Second World War became global.
Read the story →The Piltdown skull was unveiled by Charles Dawson at the Geological Society of London on 18 December 1912 as *Eoanthropus dawsoni* — the missing link between ape and human. It dominated British palaeoanthropology for forty years. The 1953 fluorine and chemical testing proved it was a modern human cranium combined with an orangutan jaw, stained with iron and chromium, with the teeth filed flat.
Read the story →From 1917, young women painting luminous watch dials were taught to point their brushes with their lips, swallowing radium with every stroke. As their jaws crumbled and their bones fractured, the companies denied everything. Grace Fryer's 1927-28 lawsuit against US Radium became a landmark of workers' rights.
Read the story →Grigori Rasputin was murdered in the cellar of the Yusupov Palace in Saint Petersburg in the early hours of 30 December 1916. The standard account given by his killer Prince Felix Yusupov has him poisoned with cyanide, shot once, attacked with a club, shot three more times, and drowned in the Neva. The autopsy supports the gunshots; it does not support either the cyanide or the drowning.
Read the story →The German parliament building in Berlin burned on the night of 27-28 February 1933. A Dutch communist named Marinus van der Lubbe was arrested at the scene and beheaded the following January. The Nazi government used the fire as pretext for the Reichstag Fire Decree of 28 February, which suspended civil liberties. The Enabling Act of 23 March made Hitler legal dictator.
Read the story →Nicholas II, his wife Alexandra, their five children, the family doctor, and three servants were shot and bayoneted in the cellar of the Ipatiev House in Yekaterinburg at approximately 1:30 a.m. on 17 July 1918. The execution was ordered by the local Ural Soviet against the approaching Czechoslovak Legion. The bodies were not recovered for 73 years. The five identified Romanov bodies were reburied at the Peter and Paul Cathedral, Saint Petersburg, in July 1998.
Read the story →Captain Robert Falcon Scott and four companions reached the South Pole on 17 January 1912, thirty-three days after Roald Amundsen's Norwegian expedition had got there first. All five died of exhaustion, frostbite, and starvation on the return march. Scott's body and his journal were found by a search party eight months later, eleven miles from the One Ton Depot they had been trying to reach.
Read the story →Ernest Shackleton's ship Endurance was beset in the Weddell Sea pack ice on 19 January 1915 and was crushed and sank on 21 November 1915. The twenty-eight men reached uninhabited Elephant Island in April 1916; Shackleton then crossed 800 miles of the southern ocean in an open lifeboat to South Georgia. All twenty-eight survived. The wreck was located on the Weddell Sea floor in 2022.
Read the story →The British Fourth Army attacked German positions along an 18-mile front in northern France on the morning of 1 July 1916. Approximately 57,470 British soldiers became casualties on the first day — 19,240 killed, 35,493 wounded, 2,152 missing, 585 captured. It is the bloodiest single day in British military history. The Battle of the Somme continued for four and a half more months.
Read the story →The 1918 influenza pandemic killed approximately 50 million people across three waves from spring 1918 to spring 1920. The death toll exceeded the First World War casualty figure. The "Spanish flu" name reflects neutral Spanish press coverage, not a Spanish origin. The viral strain (H1N1) was reconstructed from preserved Alaskan tissue in 2005.
Read the story →On 24 July 1915 a steamer chartered for a Western Electric company picnic capsized at its Chicago River mooring. 844 people died in twenty feet of water.
Read the story →Nikola Tesla's Wardenclyffe Tower on Long Island was 187 feet tall, built between 1901 and 1903 as a global wireless-power transmission station. J.P. Morgan stopped funding it in 1903. Tesla mortgaged the tower in 1915 and lost the property in 1917 when the steel was sold for $1,750 scrap value. The site is now the Tesla Science Center.
Read the story →The White Star liner RMS Titanic struck an iceberg in the North Atlantic at 11:40 p.m. on 14 April 1912 and sank at 2:20 a.m. on 15 April. Of 2,224 people aboard, 1,517 died. The ship carried lifeboats for 1,178 — about half the maximum capacity. The disaster substantially changed maritime safety regulation.
Read the story →On 18 March 1925 a single immense tornado tracked some 350 kilometres across Missouri, Illinois, and Indiana in three and a half hours, killing 695 people — the deadliest tornado in US history. Official forecasts of the era were forbidden to use the word "tornado."
Read the story →A fire began on the eighth floor of the Asch Building in Greenwich Village at 4:40 p.m. on Saturday 25 March 1911. The Triangle Shirtwaist Company occupied the eighth, ninth, and tenth floors. The exit doors had been locked from the outside to prevent theft. 146 garment workers died — most of them young immigrant women — in 18 minutes. The disaster produced the first New York State factory-safety legislation.
Read the story →On 30 June 1908 something exploded above central Siberia with the force of a hydrogen bomb. It took the first scientists nineteen years to reach the site.
Read the story →Howard Carter's workmen uncovered the first sealed step of Tutankhamun's tomb on 4 November 1922 in the Valley of the Kings. Carter had been hired by the Earl of Carnarvon in 1907 and had spent six years on the specific Tutankhamun excavation. Carnarvon had been about to cancel funding. The discovery of the substantially intact 18th-Dynasty royal tomb was the most significant Egyptological find of the 20th century.
Read the story →Mary Mallon, an Irish-born cook in New York, was the first person in the United States identified as a healthy carrier of typhoid fever. Linked to at least 53 cases and 3 deaths, she was quarantined on North Brother Island from 1907 to 1910, released on condition she stop cooking — and caught cooking again in 1915. She spent the rest of her life in quarantine.
Read the story →At 8:43 AM on 6 December 1917, Halifax telegraph dispatcher [Vince Coleman](/articles/halifax-explosion-1917) stayed at his post to warn an inbound passenger train that the burning munitions ship in the harbour was about to explode. The explosion killed him about a minute later. The brass-and-wood telegraph key he typed his last message on now lives in a glass case in Gatineau, Quebec.
Read the story →The German mark lost value at progressively faster rates from August 1922 to November 1923. The peak exchange rate of 4.2 trillion marks to the US dollar was reached on 20 November 1923. The middle-class savings of the German Empire were destroyed. The Rentenmark currency reform of November 1923 stabilised the situation but did not restore the lost wealth.
Read the story →Western Electric's Hawthorne Works in Cicero, Illinois, employed 45,000 people at peak. Between 1924 and 1932 a team of Harvard researchers studied the workforce in increasing detail. The eventual finding — that workers behave differently when they know they're being watched — gave its name to the Hawthorne Effect.
Read the story →The Wright brothers flew the world's first powered, heavier-than-air, sustained, controllable aircraft on the morning of 17 December 1903 at Kitty Hawk, North Carolina. The first flight covered 36 metres in 12 seconds. The fourth flight that day covered 260 metres in 59 seconds. Within 66 years the same trajectory of aviation development had landed humans on the Moon.
