August 6, 2017: birthday: Sir Alexander Fleming

Today is the birthday of Sir Alexander Fleming, the bacteriologist who discovered the antibacterial properties of penicillin. He was born in Lochfield, Scotland, in 1881. He came into his lab one morning in 1928 to discover he’d left the lid off of a petri dish containing a Staphylococcus culture. The culture had become contaminated by a blue-green mold, and Fleming noted that right around the moldy spots, the bacteria were no longer growing. He isolated the mold and determined it was Penicillium notatum. His first thought was that it would be useful as a surface disinfectant, and he later proved that it was effective against bacterial influenza. He later said, “One sometimes finds what one is not looking for.”
