Who disproved the theory of spontaneous generation?

Answer

For centuries many people, common and scientifically minded alike, believed in the concept of spontaneous generation. This was the concept that matter could spontaneously be generated from dissimilar materials. An example of this idea is that raw meat creates maggots or that maggots spontaneously generate from raw meat. Francesco Redi disproved spontaneous generation by showing that maggots arose from meat only when flies had access to the meat and laid their eggs in it. Spontaneous generation again became a popular belief, at least on the microbial level, when John Needham showed that if a broth was boiled, which was presumed to kill all life forms and then allowed to sit in the open air, it started growing particles. Louis Pasteur ended the debate once and for all with his famous swan-neck flask experiment.
