Sep 14, 2024 · Alexander Fleming, Scottish bacteriologist best known for his discovery of penicillin in 1928, which started the antibiotic revolution. He was recognized for that achievement in 1945, when he received the Nobel Prize for Physiology or Medicine, along with Howard Walter Florey and Ernst Boris Chain.
Fleming found that his "mold juice" was capable of killing a wide range of harmful bacteria, such as streptococcus, meningococcus and the diphtheria bacillus. He then set his assistants, Stuart Craddock and Frederick Ridley, the difficult task of isolating pure penicillin from the mold juice.

In 1928 he saw that in addition to bacteria, a mold fungus had begun to grow in a bowl and that the bacteria's growth had been impeded in the vicinity of the mold. He concluded that the mold contained a substance that was effective against bacteria.
