History and microbes
Louis Pasteur (1822-95)
Proved decay was caused by microbes in the air
Said if microbes got in body, they would cause disease, so need to prevent their entry
Joseph Lister (1827-1912)
Developed ideas of antibiotics which are solutions that kill microbes (e.g. Dettol)
Lister was a surgeon and he sprayed his instruments with carbolic acid, and this reduced infection after operations
Alexander Fleming (1881-1955)
Left an agar plate out which had bacteria growing on it, and a mould grew which caused bacteria around it to die.
The mould (Penicillium notatum) was producing penicillin and this killed bacteria
