1865 – Joseph Lister, British surgeon and scientist, performs first antiseptic surgery, using carbolic acid (phenol) as a disinfectant. Lister knew carbolic acid had been effective in municipal use for treating sewage, and decided to try using it to kill germs that would otherwise infect wounds. He poured phenol on bandages, ligatures, instruments and directly on the wound and hands. His first patient to benefit from this procedure was James Greenlees, age 12, whose broken leg was treated after being run over by a cart. The dressing was soaked with phenol and linseed oil; the wound healed without infection.
