The level which the world has reached today is because of the continuous inventions and contributions made by many people. The inventors first come up with the idea that could solve a problem, especially in a way that no one else thought of, then design it and bring the idea to the reality.
But there is also the stage where a device is 'tested,' before introducing it to everyone. And the person who dummied to check its success was the inventor himself many times. But unfortunately, a few got killed by their inventions, and here I have compiled a list of few.
1. Henry Smolinski
Henry Smolinski was a Northrop-trained engineer. He left his job because he wanted to start Advanced Vehicle Engineers, a company which focused on bringing a flying car to market. In 1973, the first two prototypes of the company were built. Later that year on Sept. 11, Smolinski went on a test flight with pilot Harold Blake. But unfortunately, they both were killed in a crash, when a wing strut got detached from the car. The National Transportation Safety Board said that it was the bad welds that led to the accident.
2. Franz Reichelt
Franz Reichelt, born in Austria, was a tailor by profession. The inventor used to spend his free time working on a flying parachute suit which was to be worn by the airplane pilots. When Reichelt was working on this design, airplanes were a new invention at that time and the mechanics of how a pilot will escape from a plane in an emergency was still in process. Reichelt did first tests of his design on the dummies which were successful, and that encouraged him to try it himself. For which he jumped off the lower level of the Eiffel Tower, which was about 187-feet. However, his jump onto the frozen ground led to his death.
3. Horace Lawson Hunley
Hunley was a marine engineer and a lawyer and served in the Louisiana state legislature as well. He had a thing for submarines and had helped to build around three of them, all of which were of different models. His first submarine, built in New Orleans in 1862, eventually sunk. His second one sunk in Mobile Bay in Alabama. Hunley himself funded his third submarine. On Oct. 15, 1863, he left on the submarine along with the seven crew members but the sub sank in the Charleston, S.C. However, a few of the members were lucky enough to survive, but the inventor i.e. Hunley lost his life.
4. Thomas Midgley Jr
The death of this inventor is a very surprising one. Midgley was a chemist and was known for his work with "no-knock" or say leaded gasoline and the greenhouse gas Freon. Once in a press conference, he poured leaded gasoline all over his hands to prove that the fuel was safe but subsequently suffered from it. But unlike our assumptions, he didn't die because of this. Rather he was killed by one of his other inventions. When he was in bed suffering from polio, he had built a rope and pulley system for himself, but due to his misfortune, he got entangled in the ropes and died due to suffocation on Nov. 2, 1944.
