Thank you, a Scot & an Aussie without whom I'd be staring another feckin' abscess in the throat.

1928: Alexander Fleming noticed a halo of inhibition of bacterial growth around a contaminant blue-green mould on a Staphylococcus plate culture. He concluded that the mould was releasing a substance that was inhibiting bacterial growth. He grew a pure culture of the mould and discovered that it was Penicillium notatum. With help from a chemist he isolated what he later named "penicillin". During the next twelve years, he grew and distributed the original mould, unsuccessfully trying to get help from any chemist that had enough skill to make a stable form of it for mass production.
