Alexander Fleming (1881-1955) was a Scottish bacteriologist who discovered lysozyme (a nasal enzyme with antibacterial properties) in 1922, and in 1928 the antibiotic drug penicillin.
Short Biography:
With H. W. Florey and E. B. Chain, he won the Nobel Prize for Medicine in 1945.
After a false start as a shipping clerk, Fleming retrained in medicine. Lysozyme was an early discovery.
While studying this, he found an unusual mould growing on a neglected culture dish. He isolated and grew it in pure culture. However, its full value was not realized until Florey and Chain isolated the active ingredient, penicillin, and tested it clinically.
