**Core Concept**
Joseph Lister, a British surgeon, introduced the concept of antisepsis to prevent puerperal sepsis and other post-operative infections. This marked a significant shift in the field of surgery and obstetrics. Lister's work was based on the germ theory of disease, which posits that microorganisms cause infections.

**Why the Correct Answer is Right**
Lister's use of carbolic acid as an antiseptic was a major breakthrough in preventing puerperal sepsis, a leading cause of maternal mortality at the time. He demonstrated that by applying carbolic acid to wounds and surgical instruments, he could significantly reduce the incidence of post-operative infections. Lister's work laid the foundation for modern antiseptic practices in healthcare.
