Lazzaro Spallanzani was an Italian priest who re-examined the spontaneous generation 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 spontaneous generation theory.
Lazzaro Spallanzani (1729–1799) did not agree with Needham’s conclusions, however, and performed hundreds of carefully executed experiments using heated broth. 3 As in Needham’s experiment, broth in sealed jars and unsealed jars was infused with plant and animal matter. Spallanzani’s results contradicted the findings of Needham: Heated ...
