In a scientific tour de force, Florey, Chain and their colleagues rapidly purified penicillin in sufficient quantity to perform the experiment that Fleming could not: successfully treating mice that had been given lethal doses of bacteria. Within a year, their results were published in a seminal paper in the Lancet...
