Louis Pasteur/Inventions
Louis Pasteur is best known for inventing the process that bears his name, pasteurization. Pasteurization kills microbes and prevents spoilage in beer, milk, and other goods. In his work with silkworms, Pasteur developed practices that are still used today for preventing disease in silkworm eggs.
Who discovered the autoclave?
Charles Chamberland
The autoclave was invented by Charles Chamberland in 1879, although a precursor known as the steam digester was created by Denis Papin in 1679.
Can virus pass through porcelain?
studies of the disease along bacteriological lines had only led to nega- tive results, and filtration experiments with very dense porcelain filters had shown that the virus could pass through the pores, his conclusion that the infective principle was present in solution does not seem un- natural.
What is a Chamberland filter candle?
This was developed in 1884 in Paris by Charles Chamberland, who worked with Louis Pasteur. It consisted of unglazed porcelain “candles”, with pore sizes of 0.1 – 1 micron (100 – 1000 nm), which could be used to completely remove all bacteria or other cells known at the time from a liquid suspension.

Did Louis Pasteur invent vaccines?
In 1881, he helped develop a vaccine for anthrax, which was used successfully in sheep, goats and cows. Then, in 1885, while studying rabies, Pasteur tested his first human vaccine. Pasteur produced the vaccine by attenuating the virus in rabbits and subsequently harvesting it from their spinal cords.
