Francesco Redi
Francesco Redi was an Italian physician, naturalist, physiologist, and writer. He was the first man to prove tht the Spontaneous generation was wrong. In his experiment, he put on three jars a pice of meat, and covered them using different materials. The first jar didn't have a covering, the second one was sealed and the third one was covered using cloth netting. With this experiment, he proved that rotting meat didn't produce maggots. -
John Needham
John Turberville Needham was an English biologist and Catholic priest. Needham claimed that spontaneus generation existed, he proved his thoughts with an experiment that consisted of heatting broth to its boiling pont, to kill all the microorganisms, then put it into some flasks, when the broth cooled, he sealed them. He waited a little bit and he observed living organisms in the sealed broth. Then he concluded that spontaneous generation was real. -
Lazzaro Spallanzani
Lazzaro Spallanzani was a naturalist and Catholic priest. He did a experiment to prove that the theory of spontaneous generationgs was real. For his experiment he boiled two separate flasks for an extended period, sealed one immediately and left the second open to the air. The open flask developed microorganisms while the sealed flask did not. Would this disprove the theory of spontaneous generation for good? Unfortunately, this did not happen. -
Louis Pasteur
Louis Pasteur was a French chemist, physicist, mathematician and bacteriologist, whose discoveries were of enormous importance in various fields of natural sciences, especially chemistry and microbiology. He made lots of important discoveries such as the pasteuritzation experiment. In 1859 he made a experiment in which he showed that a boiled nutrient broth did not give rise spontaneously to new life. With that he proved wrong the theory of spontaneous generation.
