We have mentioned five inventions and their inventors, which were very useful, but ironically, their own inventions proved to be the time for those inventors.
1. Horace Lawson Hunley: Born December 29, 1823 in Summer County, USA, Horace Lawson Hunley was a government marine engineer by profession during the American Civil War. He invented the first hand-held marine submarine.
However, the submarine sank in the sea during the test. Hanley, along with other crew members, was in the same submarine. The crew members, including Pari Hanley, were killed in the crash.
2. Henry Smolensky: The American scientist Henry Smolensky invented the flying car in 1973. The flying car was named Ave Mizar. Smolinsky was killed when his car crashed during a test flight.
3. Franz Richelett: You've seen people dressed like birds' wings, jumping from the top of a hill and flying down to a ravine. A garment that makes a person fly like a bird is called a wingsuit. Such a modern winged dress was invented in 1912.
Franz Richelt, a 33-year-old Austrian tailor by profession, invented the wingsuit. On February 4, 2012, he jumped out of the Eiffel Tower in Paris to test his wingsuit. But ironically, his test was not successful. He died on the spot.
4. Madame Curie: Madame Curie, a world-renowned physicist and chemist who discovered two elements, radium and polonium, died in 1934. Curie, who was involved in the research of radioactivity, was seriously affected by the radiation and died.
5. William Bullock: Born in Greenville, USA, William Bullock is considered to be the scientist who radically improved the Rotary printing press created by Richard March Hoy. Due to him, the printing press industry was revolutionized. However, he died while repairing a self-made printing press.
