In 1800 the origins of infectious diseases were unknown and as mysterious as they had been in the Middle Ages.

“Spontaneous generation” was the idea that living organisms can spring into existence from non-living matter. In the late 19th century, in a showdown between chemist Louis Pasteur and biologist Felix Pouchet put on by the French Academy of Sciences, Pasteur famously came up with an experiment that debunked the theory.
