Did Pasteur Disprove Spontaneous Generation?

Louis Pasteur is credited with conclusively disproving the theory of spontaneous generation with his famous swan-neck flask experiment. He subsequently proposed that “life only comes from life.”

What is spontaneous generation how Louis Pasteur disprove it?

The broth in the broken flasks quickly became cloudy—a sign that it teemed with microbial life. However, the broth in the unbroken flasks remained clear. Without the introduction of dust—on which microbes can travel—no life arose. Pasteur thus refuted the notion of spontaneous generation.

Who disproved the idea of spontaneous generation?

Though challenged in the 17th and 18th centuries by the experiments of Francesco Redi and Lazzaro Spallanzani, spontaneous generation was not disproved until the work of Louis Pasteur and John Tyndall in the mid-19th century.
