Though challenged in the 17th and 18th centuries by the experiments of the Italian biologists Francesco Redi and Lazzaro Spallanzani , it was not discredited until the work of the French chemist Louis Pasteur and the Irish physicist John Tyndall in the mid-19th century.

By turn of mind Redi was the precursor of the modern exper imental biologist. Therefore, he determined to test the familiar aspects of spontaneous generation by actual controlled experiment, for the first time in the history of natural science. His experi ments were simple.
