Anton von Leeuwenhoek
Discoveries that led to the invention of the first light microscope. Made over 400 microscopes with natural light source. Viewed the first microorganisms he called “animalcules.”
Animalcules

Francesco Redi
Maggots on meat experiment. First time he used a sealed flask and open flask and proved that maggots come from flies. Second time he used a gauze-covered flask and open flask and proved that maggots come from flies.
The man who showed that complex (large, multi-cellular) organisms do not originate through spontaneous generation.
Francesco Redi
Performed a second experiment with flasks and maggots in an attempt to please critics to disprove spontaneous generation.
Francesco Redi
Spontaneous generation
The theory that living organisms can originate from non-living things.
Biogenesis
The theory that living organisms must originate from other living organisms.
The theory that living organisms can originate from non-living things.
Spontaneous generation
The theory that living organisms must originate from other living organisms.
Biogenesis
Louis Pasteur
Disproved theory of spontaneous generation and developed process of pasteurization.
Louis Pasteur and spontaneous generation vs. biogenesis experiment used what?
Straight necked flasks and S-shaped necked flasks.
In Louis Pasteur’s spontaneous generation/biogenesis experiment, whose work did he support?
Francesco Redi
What theory did Louis Pasteur’s experiments using S-shaped necked flasks disprove?
Spontaneous generation
