Francesco Redi
Francesco Redi was an Italian physician and biologist who is known for his experimental work in the field of spontaneous generation.
He conducted a series of experiments involving meat, maggots, and flies, in which he showed that maggots did not arise spontaneously from meat, but rather from eggs laid by flies.
These experiments helped to disprove the theory of spontaneous generation and paved the way for the development of modern germ theory. -
John Needham
n an experiment, Needham boiled beef broth and then sealed the container, but later observed the growth of microorganisms, which he believed to have arisen spontaneously.
However, his results were later challenged by other scientists, including Lazzaro Spallanzani, who repeated the experiment and showed that the microorganisms only grew when the seal was broken, indicating that they came from the air rather than arising spontaneously. -
Lazzaro Spallanzani
Lazzaro Spallanzani was an 18thcentury Italian biologist and physiologist who is known for his work on spontaneous generation.He carried out experiments in which he demonstrated that microorganisms came from the air and did not arise spontaneously as was believed at the time.He also investigated animal digestion and respiration aswell as heat conservation in animals among other topics.His studies in biology and physics laid the foundationfor the principles of thermodynamics and modern physiology -

Louis Pasteur was a 19th century French chemist and microbiologist.
He is known for his studies on fermentation and the development of the pasteurization technique to prevent putrefaction of food and drinks.
