Penicillin was discovered by chance by Alexander Fleming in 1928 when Penicillium spores had been introduced to the culture medium accidentally in which he was using to investigate staphylococcus. Fleming initially used the mould to put on wounds as a disinfectant and it was Howard Florey and Ernst Chain that provided evidence that penicillin could be used against bacteria. https://hekyll.services.adelaide.edu.au/dspace/handle/2440/38832
