Winner of two Nobel prizes, Marie Curie was both chemist and physicist. She was best known for her work on radioactivity; she also discovered the elements radium and polonium. The person responsible for establishing the theory of radioactivity is Marie, but unfortunately, she unintentionally discovered the fatal effect radioactivity could have on the health of human beings. And she died because of aplastic anemia caused by radiation exposure on July 4, 1934.
6. Perillos of Athens
Perillos actually deserved to die at the hand of his own inventions.
He was a bronze worker who designed a device to present to the king so that the latter could punish the criminals as cruelly as possible. The device was called the Brazen Bull, where the criminals were locked inside, and a fire was set beneath the statue because of which the metal heated until the victims inside died from severe burns.
The structure of the bull was designed with a system of pipes and tubes, which was to convert the screams of the victims to the sounds similar to the bellowing of an enraged bull. Perillos once said, "The horrendous screams will come to you through the tubes as the tenderest, most melodious, most pathetic of bellowings." Well, it is also interesting to know that when Perillos proposed the Brazen Bull to Phalaris, the latter was so disgusted by the brutality of this invention and ordered to put the former inside the bull and get him roasted.
