Joseph Lister was a British surgeon born in 1827 who introduced antiseptic surgery through the use of carbolic acid spray. He developed these techniques after reading about Louis Pasteur's germ theory of disease. Prior to Lister's work, patients often died after surgery from infections. Through the use of antiseptics like carbolic acid, Lister was able to significantly reduce surgical infection rates and save countless lives, establishing him as the father of modern antiseptic surgery. His techniques formed the basis of modern aseptic surgical practices and prevented millions of deaths from surgery.
