1911: The Mona Lisa Stolen from the Louvre by a Museum Employee

In the early hours of 21 August 1911, Vincenzo Peruggia, an Italian handyman who had worked at the Louvre, hid inside the museum overnight, lifted Leonardo da Vinci’s Mona Lisa from the wall, concealed it under his coat, and walked out. The theft went unnoticed for nearly 24 hours. The empty hooks on the wall were initially assumed to mean the painting had been taken for photography.

Peruggia kept the masterpiece hidden in his Paris apartment for over two years before attempting to sell it to an art dealer in Florence. He was arrested in December 1913, and the painting was recovered intact. Peruggia claimed he had acted out of Italian patriotism, believing the work had been stolen by Napoleon and deserved to be returned to Italy. He served just seven months in prison.

1940: Leon Trotsky Assassinated by Soviet Agent in Mexico

Leon Trotsky, Russian revolutionary and founder of the Red Army, was attacked at his fortified home in Coyoacan, Mexico City, on 20 August 1940. The attacker, Ramon Mercader, was an undercover agent of the Soviet secret police, the NKVD, who had spent months gaining the trust of those in Trotsky’s inner circle.

Mercader struck Trotsky with an ice axe, inflicting a fatal wound to the skull. Trotsky died the following day, aged 60. Mercader was arrested at the scene, convicted of murder, and served 20 years in a Mexican prison. He was later awarded the Hero of the Soviet Union medal by Stalin.

1960: Francis Gary Powers Pleads Guilty at Moscow Spy Trial

On 17 August 1960, American pilot Francis Gary Powers stood trial in Moscow after his U-2 reconnaissance aircraft was shot down over Soviet airspace on 1 May 1960. Powers, flying a CIA surveillance mission, had been captured alive when his high-altitude spy plane was struck by a Soviet surface-to-air missile near Sverdlovsk.

Powers pleaded guilty to espionage charges before a Soviet military tribunal, in a trial that became a Cold War spectacle broadcast to the world. He was sentenced to ten years, serving nearly two before being exchanged for Soviet spy Rudolf Abel at the Glienicke Bridge in Berlin in February 1962.

1751: The Poisoning of Francis Blandy by His Own Daughter

Francis Blandy, a lawyer and town clerk of Henley-on-Thames, died in August 1751 after his daughter Mary repeatedly dosed his food with arsenic. The powder had been supplied by her lover, Captain William Henry Cranstoun, a Scottish officer who was already secretly married. Cranstoun told Mary the powder would make her father more accepting of their betrothal. His death became one of the earliest criminal cases to feature scientific toxicological evidence.

Mary was arrested after servants and relatives raised suspicions. Tried at Oxford in February 1752, she was convicted of murder and hanged on 6 April 1752, protesting her innocence to the end. Cranstoun escaped justice in court but died of illness in December 1752.
