Who was the key figure behind the development of antiseptic surgery?

Joseph Lister was the key figure behind the development of antiseptic surgery. His pioneering work in the late 19th century introduced the use of carbolic acid (phenol) as a disinfectant during surgical procedures, significantly reducing the risk of infection and death.

Prior to Lister's innovations, the prevailing medical practices did not prioritize cleanliness and hygiene, often resulting in high rates of post-surgical infections. Lister's application of germ theory, which had been developed by Louis Pasteur, demonstrated that microorganisms could cause infections, leading him to advocate for antiseptic methods in operating theatres. His meticulous methods and emphasis on sterilization transformed surgical practices globally, improving patient outcomes and setting new standards in medical care.

In contrast, Edward Jenner is celebrated for developing the smallpox vaccine, Alexander Fleming is known for discovering penicillin, and Florence Nightingale made immense contributions to nursing practices and hospital sanitation but did not focus directly on surgical procedures or antiseptics.
