From Fleming’s Petri Dish to a Global Cancer Registry: Turning Signals into Evidence

In 1928, Alexander Fleming returned from holiday to his cluttered laboratory at St. Mary’s Hospital in London and noticed something that most would have discarded. A mold had contaminated one of his petri dishes. Around the mold, the staphylococcal bacteria were dead. He isolated the substance, named it penicillin, and showed its effect. Years passed before it became a practical, usable medicine. Fleming never became a rich man from the discovery. He shared the 1945 Nobel Prize with Howard Florey and Ernst Chain, yet always stressed that such a finding should serve humanity openly. Some occurrences arrive with a sense that they are larger than any one person or profit motive. They carry an unspoken call to be shared openly, as if given for the benefit of all.
