The discovery of penicillin, one of the world’s first antibiotics, marks a true turning point in human history — when doctors finally had a tool that could completely cure their patients of deadly infectious diseases.
Many school children can recite the basics. Penicillin was discovered in London in September of 1928. As the story goes, Dr. Alexander Fleming, the bacteriologist on duty at St. Mary’s Hospital, returned from a summer vacation in Scotland to find a messy lab bench and a good deal more.
Upon examining some colonies of Staphylococcus aureus, Dr. Fleming noted that a mold called Penicillium notatum had contaminated his Petri dishes. After carefully placing the dishes under his microscope, he was amazed to find that the mold prevented the normal growth of the staphylococci.

It took Fleming a few more weeks to grow enough of the persnickety mold so that he was able to confirm his findings. His conclusions turned out to be phenomenal: there was some factor in the Penicillium mold that not only inhibited the growth of the bacteria but, more important, might be harnessed to combat infectious diseases.
As Dr. Fleming famously wrote about that red-letter date: “When I woke up just after dawn on September 28, 1928, I certainly didn’t plan to revolutionize all medicine by discovering the world’s first antibiotic, or bacteria killer. But I guess that was exactly what I did.”
Fourteen years later, in March 1942, Anne Miller became the first civilian patient to be successfully treated with penicillin, lying near death at New Haven Hospital in Connecticut, after miscarrying and developing an infection that led to blood poisoning.
But there is much more to this historic sequence of events.
Actually, Fleming had neither the laboratory resources at St. Mary’s nor the chemistry background to take the next giant steps of isolating the active ingredient of the penicillium mold juice, purifying it, figuring out which germs it was effective against, and how to use it. That task fell to Dr. Howard Florey, a professor of pathology who was director of the Sir William Dunn School of Pathology at Oxford University. He was a master at extracting research grants from tight-fisted bureaucrats and an absolute wizard at administering a large laboratory filled with talented but quirky scientists.
This landmark work began in 1938 when Florey, who had long been interested in the ways that bacteria and mold naturally kill each other, came across Fleming’s paper on the penicillium mold while leafing through some back issues of The British Journal of Experimental Pathology. Soon after, Florey and his colleagues assembled in his well-stocked laboratory. They decided to unravel the science beneath what Fleming called penicillium’s ”antibacterial action.”
