Joseph Lister (1827 โ 1912) was a British surgeon and a pioneer of antiseptic surgery. He promoted the idea of sterile surgery while working at the Glasgow Royal Infirmary. By applying Louis Pasteur's germ theory, Lister introduced carbolic acid (phenol) to sterilize surgical instruments and clean wounds. Think of him as the father of modern surgery, reducing infections and saving countless lives. His methods were revolutionary.
