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's fortuitous discovery of penicillin—the mold had accidentally contaminated a Staphylococcus culture plate and exhibited a bacteria -free halo around the mold—was one of the seminal developments in the history of medicine.
The mold, he discovered, had been created by a spore of a rare variant called Penicillium notatum, which had likely drifted up from a mycology lab on another floor. Fleming named this mold substance “penicillin” and reported his findings in 1929 in the British Journal of Experimental Pathology.
In 1928 he inadvertently discovered penicillin when he noticed that a mold contaminating a bacterial culture was inhibiting the bacteria’s growth. He shared a 1945 Nobel Prize with Ernst Boris Chain and Howard Walter Florey, who both carried Fleming’s basic discovery further in isolating, purifying, testing, and producing penicillin in quantity.
