What did Francesco Redi and Louis Pasteur demonstrate in their experiments?
Francesco Redi and Louis Pasteur, as well as Lazzaro Spallanzani and John Tyndall, all did scientific experiments (as opposed to philosophical writings) challenging the idea that life could quickly arise in the absence of any life from which other life could grow. This idea, formally dating back to the ancient Greeks, is called "spontaneous generation." The experiments of these four showed that spontaneous generation did not occur in situations that others thought it did. Like any good science controversy, other scientists did experiments that supported spontaneous generation, but Pasteur and Tyndall were able to do experiments that were rigorous enough to unambiguously disprove this idea.
