Antiseptic surgery

In 1867, the Lancet published a paper by Joseph Lister, the first of a series of articles in the Lancet on his discovery of antiseptic surgery: On a New Method of Treating Compound Fractures, Abscess, &c. Lister applied Louis Pasteur's idea that the micro-organisms causing gangrene might be controlled with chemical solutions. Since the use carbolic acid (phenol) was known as means of deodorizing sewage, Lister tested the results of using a solution of it for spraying instruments, on surgical incisions, and applied to dressings. Upon finding this procedure substantially reduced the incidence of gangrene, Lister published his results in series of articles in the Lancet on the Antiseptic Principle of the Practice of Surgery.«[Ref: Lancet (16 Mar 1867), 327, (23 Mar), 357, (30 Mar), 387.]
