Branded a traitor during the Reign of Terror, French chemist Antoine Lavoisier, who was also a tax collector with the Ferme générale, is tried, convicted and guillotined in one day in Paris.

On May 8, 1794, pioneering chemist Antoine Lavoisier was condemned as a traitor and executed by guillotine during the Reign of Terror.
Antoine Lavoisier, renowned for laying the foundations of modern chemistry, was arrested in April 1794 for his role as a tax collector with the Ferme générale. Despite his scientific achievements, revolutionary zeal branded him a counter-revolutionary. He was brought to trial, convicted, and executed by guillotine in a single day at the Place de la Révolution in Paris. His death shocked the intellectual community, leading figures to lament that 'the Republic has no use for geniuses.' Lavoisier’s pioneering work on oxygen and the law of conservation of mass survived his martyrdom and continued to influence chemical science. His execution remains a stark example of the revolution’s excesses and the peril faced by the Enlightenment elite.

Attempting to make the first non-stop transatlantic flight from Paris to New York, French war heroes Charles Nungesser and François Coli disappear after taking off aboard The White Bird biplane.

In 1927, aviation pioneers Charles Nungesser and François Coli vanished while attempting the first nonstop transatlantic flight from Paris to New York.
On May 8, 1927, French aviators Charles Nungesser and François Coli took off from Paris aboard The White Bird biplane, aiming to make history with the first nonstop flight to New York. As they flew across the Atlantic, the aircraft disappeared over the ocean, sparking one of aviation's enduring mysteries. Their ambitious plan predated Charles Lindbergh's successful flight by just weeks. Despite extensive searches, no conclusive wreckage or survivors were ever found. The pair's daring attempt captured global imagination and highlighted the extraordinary risks of early long-distance flight. Today, their legacy endures as a testament to courage and the relentless pursuit of human progress in aviation.

The Tollund Man was discovered in a peat bog near Silkeborg, Denmark.

The remarkably well-preserved bog body known as the Tollund Man was unearthed in a Danish peat bog, sparking fascination among scientists and the public.
In 1950, the perfectly preserved body of a man from the Iron Age was unearthed in a peat bog near Silkeborg, Denmark, later dubbed the Tollund Man. The discovery astonished scientists and the public for its remarkable preservation of skin, facial features, and hair. Radiocarbon dating revealed he lived around the 4th century BCE, offering an extraordinary glimpse into prehistoric European culture. Scholars have used his remains to study ancient diet, customs, and the spiritual significance of bog burials. Today, the Tollund Man is one of the most famous bog bodies, displayed at the Silkeborg Museum and captivating visitors worldwide.

The World Health Organization confirms the eradication of smallpox.

The World Health Organization formally declares smallpox eradicated worldwide.
On May 8, 1980, the World Health Organization (WHO) officially certified the global eradication of smallpox, marking the first time a human disease was completely eliminated. This milestone followed an intensive, decade-long vaccination campaign coordinated across more than 196 countries. Health workers overcame logistical, political, and cultural challenges to reach remote and conflict-affected regions. The eradication effort set a precedent for coordinated international public health initiatives. WHO Director-General Dr. Halfdan Mahler hailed the achievement as 'a health victory of unparalleled magnitude.' The success of the smallpox campaign inspired subsequent eradication programs, including efforts against polio and guinea worm disease. Today, the eradication of smallpox stands as a testament to the power of global cooperation in science and medicine.

British 17-year-old Isabelle Holdaway is reported to be the first patient ever to receive a genetically modified phage therapy to treat a drug-resistant infection.

In 2019, 17-year-old Isabelle Holdaway became the first patient to receive a genetically modified phage therapy to treat a drug-resistant bacterial infection.
On May 8, 2019, British teenager Isabelle Holdaway was treated with a custom-engineered bacteriophage therapy to combat a multidrug-resistant Mycobacterium abscessus infection. The experimental treatment involved modifying naturally occurring viruses to specifically target and kill antibiotic-resistant bacteria. This landmark case marked the first successful use of genetically modified phages in a human patient. Within 48 hours, the therapy began reducing bacterial load, offering hope for patients with infections that do not respond to traditional antibiotics. Medical teams coordinated across multiple research institutions to develop, test, and deliver the tailored phage solution. The success of this treatment opened new avenues for addressing the growing global threat of antimicrobial resistance.
