Les Cinglés Français, Vol. 2 — Ingénieurs et Aventuriers
The first list was artists, poets, philosophers. This one is engineers, scientists, explorers, soldiers. Different kind of crazy. Less opium, more frostbite.
1. Gustave Eiffel (1832–1923)
Built the Eiffel Tower (1889), which the entire Parisian intellectual establishment publicly despised. Maupassant ate lunch at the Tower restaurant every day because it was the only place in Paris where he couldn't see it. Built the internal iron skeleton of the Statue of Liberty. Then: got implicated in the Panama Canal corruption scandal, was convicted, sentenced to prison, had the conviction overturned on appeal, and watched his engineering reputation collapse overnight.
He was 61. Instead of retiring, he turned the Eiffel Tower into a scientific laboratory. He built one of the first aerodynamic wind tunnels in the world at its base. He spent his final 32 years doing groundbreaking research in aerodynamics and meteorology, essentially inventing a second career from scratch on the ruins of the first.
The insane part: the wind tunnel. After everything that happened, he used the Tower he built as a tool to become a pioneer of a completely different field. Most people would have gone home.
2. Louis Braille (1809–1852)
Blinded at 3 years old in a workshop accident: a tool slipped. At 15, he invented the Braille writing system, a 6-dot tactile code that allowed blind people to read and write at full speed for the first time. He based it on a military night-writing system developed for soldiers to communicate in the dark without speaking.
The school where he taught refused to adopt his system for 30 years after he invented it. He died of tuberculosis at 42, having never seen his invention formally accepted. The Catholic Church, which ran institutions for the blind, suppressed Braille because it allowed blind people to read without being read to: it gave them independence from intermediaries. His system was officially adopted in France two years after his death.
The insane part: a 15-year-old blind kid reverse-engineered a military encryption system and turned it into a universal literacy tool. The people running education for the blind spent 30 years blocking it.
3. Louis Pasteur (1822–1895)
Disproved spontaneous generation. Invented pasteurization. Developed vaccines for chicken cholera, anthrax, and rabies. At 45, suffered a severe stroke that left half his body paralyzed. Continued working for 27 more years. In 1885, with the rabies vaccine not yet fully tested in animals, a 9-year-old boy named Joseph Meister was brought to him, bitten 14 times by a rabid dog. Pasteur had never vaccinated a human. He vaccinated the boy anyway, across 13 injections over 10 days. The boy survived.
The insane part: Pasteur was not a medical doctor. He was a chemist. He could have been prosecuted if the boy had died. He knew this. He vaccinated him anyway because the alternative was certain death.
4. Pierre et Marie Curie (1859–1906 / 1867–1934)
Together, they discovered polonium and radium, coined the term "radioactivity," and fundamentally changed physics. Marie won the Nobel Prize in Physics (1903) and the Nobel Prize in Chemistry (1911): the first person to win two Nobels in different sciences. Pierre, before dying, was deliberately irradiating his own arm to study the effects of radioactivity on human tissue. He kept detailed notes on the burns. He died in 1906 crossing the street in the rain, slipping under a horse-drawn carriage: his skull was crushed by a wheel. Marie continued working alone for 28 more years and died of aplastic anemia caused by decades of radiation exposure. She carried radioactive isotopes in her pockets. Her personal notebooks are still too radioactive to handle without protective equipment.
The insane part: her notebooks. Stored in a lead-lined box at the Bibliothèque nationale de France. You must sign a waiver before you can read them. They will remain radioactive for another 1,500 years.
5. Sadi Carnot (1796–1832)
Published Réflexions sur la puissance motrice du feu in 1824 at age 28: a single book that founded thermodynamics, established the theoretical maximum efficiency of heat engines (the Carnot cycle), and laid the groundwork for the second law of thermodynamics. Nobody paid attention. The book sold poorly. He died of cholera at 36. After his death, his notes were destroyed by sanitary authorities who feared the disease had contaminated his papers. Some survived. What survived was enough to reshape all of physics.
The insane part: he published one book. Nobody read it. He died 8 years later. That book eventually became the foundation of all modern engine design, refrigeration, and the concept of entropy.
6. Louis de Broglie (1892–1987)
In his PhD thesis in 1924, proposed that matter has wave properties: that electrons, protons, all particles, are also waves. His thesis committee was so confused they sent the manuscript to Einstein before deciding whether to pass him. Einstein said it was correct. De Broglie got his doctorate. Five years later he won the Nobel Prize in Physics. His thesis was 70 pages. It is one of the most consequential 70-page documents in scientific history.
The insane part: the committee nearly failed him. If Einstein had said "I don't know," de Broglie might have had to rewrite the thesis that described one of the fundamental properties of matter.
7. Henri Poincaré (1854–1912)
Invented topology. Contributed foundational work to complex analysis, algebraic geometry, celestial mechanics, and the theory of differential equations. Described the qualitative behavior of dynamical systems that would eventually become chaos theory, 60 years before anyone used that term. Independently developed most of the mathematical framework of special relativity before Einstein published in 1905. Died without a Nobel Prize because the committee didn't understand his work well enough to evaluate it.
The insane part: he worked in nearly every branch of mathematics that existed in his time and made fundamental contributions to most of them. He also wrote popular science books that sold enormously. He was asked how he did it. He said he worked in short bursts of 2 hours and trusted his subconscious to do the rest overnight.
8. Jacques Cousteau (1910–1997)
Co-invented the Aqua-Lung (scuba diving equipment) in 1943 with Émile Gagnan, making underwater exploration available to humans for the first time. Converted a former minesweeper into the Calypso, his research vessel, and spent 40 years sailing and diving with a crew of scientists and filmmakers. Won the Palme d'Or at Cannes for an underwater documentary. Invented a mobile underwater habitat (Conshelf) where humans lived on the seafloor for weeks. His TV series ran for decades and introduced an entire generation to the ocean.
The insane part: before scuba, he was a naval officer who survived being shot and tortured by the Gestapo. He then invented a way to breathe underwater. Then he made films. Then he became an environmentalist. He kept reinventing himself every 10 years until he was 87.
9. René Caillié (1799–1838)
First European to reach Timbuktu and return alive (1828). The Geographical Society of Paris had offered a 10,000-franc prize for anyone who could do it. Timbuktu was considered unreachable by outsiders: the previous European to enter had been killed. Caillié spent years preparing, learned Arabic, converted (sincerely, he claimed) to Islam, and traveled disguised as an Egyptian Muslim returning from captivity. He walked over 3,000 kilometers across West Africa and the Sahara, contracted scurvy and had his palate partially destroyed by a tropical disease, and reached Timbuktu in April 1828. He was disappointed: he expected a golden city and found mud houses. He walked back across the Sahara and the Atlas Mountains to Morocco and made it to France.
The insane part: he was 29 years old. He funded the entire expedition himself. When he returned to France, the British Geographical Society accused him of lying because they couldn't believe a Frenchman had done it.
10. Alexandra David-Néel (1868–1969)
First Western woman to enter Lhasa, Tibet (1924). Tibet was closed to foreigners. She was 55 years old. She disguised herself as a Tibetan pilgrim: shaved her head, dyed her hair black with Chinese ink, dressed in rags, and walked through the Himalayas in winter with a single companion. The journey took months. She had already spent 14 years studying Buddhism and Tibetan language in India and Nepal. She spoke Tibetan fluently. She wrote 30 books. She died at 100 years old, reportedly asking her notary to renew her passport so she could travel again.
The insane part: at 100, still renewing the passport. That's not a biographical detail. That's a worldview.
11. Michel Vieuchange (1904–1930)
Smara was a forbidden holy city deep in the Western Sahara, never visited by a Westerner. In 1930, Vieuchange decided to go. Because foreigners were killed on sight, he traveled hidden inside a large sack, folded and carried by his guide, coming out only at night. He was 26, frail, and had never done anything like this before. He reached Smara. He spent three hours there. On the way back, he contracted severe dysentery and nearly died in the desert. He made it to Agadir and died there three weeks later from the illness. He was 26. His journal was published posthumously by his brother. It became a classic of French travel literature.
The insane part: he traveled hundreds of kilometers folded inside a bag. The only reason we know this is because he kept a journal the entire time, writing in the dark inside the sack.
12. Théodore Monod (1902–2000)
Naturalist, botanist, explorer, and pacifist. Made over 20 major expeditions into the Sahara on foot. Was convinced that a large meteorite had fallen somewhere in the central Sahara and spent decades looking for it on solo treks. Never found it. Made his last major Saharan crossing on foot at age 90, covering hundreds of kilometers in extreme heat with minimal equipment. He was also a committed Christian, a vegetarian, a pacifist who refused military service, and a colonial-era scientist who was nonetheless deeply critical of colonialism. He lived to 98 and was intellectually active until the end.
The insane part: the meteorite. He crossed the Sahara on foot at 90, alone, looking for a rock he believed was there. He never found it. He was not deterred. He would have gone again.
13. Éric Tabarly (1931–1998)
The man who made offshore sailing a French national obsession. Won the OSTAR (solo transatlantic race) in 1964, defeating the entire British fleet in a boat he largely designed himself. Won it again in 1976. Built and sailed some of the most technically radical boats of the 20th century. Trained an entire generation of French sailors who went on to break every record. Fell overboard at night in the Irish Sea in 1998, in rough weather, near the Welsh coast. His crew found his body the next day. He had been sailing those waters for 40 years.
The insane part: he hated interviews, hated publicity, hated being called a hero. He just sailed. When he was asked after winning the 1964 transatlantic race what he felt, he said: "Nothing special. I was at sea."
14. Michel Ney (1769–1815)
Napoleon's most reckless marshal, called "the bravest of the brave" by Napoleon himself (not a man who gave compliments easily). At Waterloo, after Napoleon's lines broke and the battle was lost, Ney had five horses shot out from under him in a single afternoon and continued fighting on foot, sword in hand. He was the last French officer to leave the battlefield. After Napoleon's final defeat, he was arrested, tried for treason by the restored Bourbon monarchy, and condemned to death. He refused to flee. At his execution by firing squad, he refused a blindfold, addressed the soldiers, and gave the order to fire himself.
The insane part: he commanded his own execution. Standing up, no blindfold, facing the rifles. The soldiers were reportedly trembling. He was not.
15. Sylvain Tesson (born 1972)
Spent 6 months alone in a wooden cabin on the shore of Lake Baikal in Siberia, in winter, with no internet and minimal supplies, reading and writing. Then walked across the Himalayas. Then crossed Asia by motorcycle. Then in 2014, fell off a roof in Chamonix while drunk at 3am, fell 8 meters, fractured his skull, broke multiple vertebrae, and spent months relearning to walk. His recovery: he decided to walk across France using only forgotten medieval paths. Then wrote the book. Then cycled from Siberia to India. He has published 15 books. He is 53.
The insane part: after nearly dying falling off a roof drunk, his rehabilitation plan was to walk across an entire country alone. This is either profound or insane. Probably both.
Vol. 1 was artists and poets. This is Vol. 2. There will be a Vol. 3.
