Florey and Chain

Howard Florey and Ernst Chain were scientists who, in the late 1930s and early 1940s, developed a method to produce penicillin, the first antibiotic. Their work involved isolating and refining the compound from mold, making it usable as a medicine. Penicillin revolutionized medicine by effectively treating bacterial infections that were often deadly before. For this groundbreaking contribution, Florey, Chain, and their colleague Alexander Fleming (who first discovered penicillin in 1928) shared the Nobel Prize in Physiology or Medicine in 1945, significantly advancing modern healthcare and saving millions of lives.
