3.1: Spontaneous Generation - Biology LibreTexts
Prominent scientists designed experiments and argued both in support of (John Needham) and against (Lazzaro Spallanzani) spontaneous generation. LouisPasteur is credited with conclusively disproving the theory of spontaneous generation with his famous swan-neck flask experiment.
Describe the theory of spontaneousgeneration and some of the arguments used to support it. Explain how the experiments of Redi and Spallanzani challenged the theory of spontaneousgeneration.
1.3: The Myth of Spontaneous Generation - Biology LibreTexts
Lazzaro Spallanzani was an Italian priest who re-examined the spontaneousgeneration of microorganisms (e.g. bacteria) using a nutrient-rich broth such as a meat broth. He designed and conducted a famous experiment that began to question the validity of spontaneousgenerationtheory.
Spontaneous generation - Wikipedia
Spontaneous generation was taken as scientific fact for two millennia. 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.
Lazzaro Spallanzani - Wikipedia
His research on biogenesis paved the way for the downfall of the theory of spontaneous generation, a prevailing idea at the time that organisms develop from inanimate matters, though the final death blow to the idea was dealt by French scientist Louis Pasteur a century later.
Lazzaro Spallanzani - Oxford Reference
Spallanzani's most important experiments, published in 1767, questioned John Needham's ‘proof’ 20 years earlier of the spontaneousgeneration of microorganisms. He took solutions in which microorganisms normally breed and boiled them for 30 to 45 minutes before placing them in sealed flasks.

Spallanzani found significant errors in the experiments conducted by Needham and, after trying several variations on them, disproved the theory of spontaneous generation.

Prominent scientists designed experiments and argued both in support of (John Needham) and against (Lazzaro Spallanzani) spontaneous generation. LouisPasteur is credited with conclusively disproving the theory of spontaneous generation with his famous swan-neck flask experiment.
Lazzaro spallanzani: A blow against spontaneous generation
His investigations into the development of microscopic life in nutrient culture solutions may be considered as decisive steps to counteract the leading theory of spontaneousgeneration and paved the way for the research work of Louis Pasteur.
