Born on August 6, 1881, in Lochfield, Scotland, Fleming studied medicine at St. Mary's Hospital Medical School of the University of London. After graduation, he devoted his career to studying bacteria and disease-causing microbes, continuing his research while serving in the Royal Army Medical Corps during World War I.
In 1928, while examining Staphylococcus bacteria, Fleming noticed that a stray mold, Penicillium rubens, had contaminated one of his culture plates. Surprisingly, bacteria surrounding the mold had been destroyed. He identified the mold's bacteria-killing substance and named it penicillin, recognizing its remarkable ability to stop bacterial growth even in tiny amounts.
Although Fleming was unable to produce penicillin on a large scale, Ernst Chain and Howard Florey later refined and mass-produced it for medical use. Introduced widely in 1941, penicillin revolutionized medicine.
Fleming was knighted in 1944 for his contributions and passed away on March 11, 1955, leaving a lasting legacy in modern healthcare.
