Joseph Lister

1827–1912 · Britain · Founder of antiseptic surgery.

Contribution

From 1867, applied Pasteur’s germ ideas to surgery: carbolic acid (phenol) to sterilize instruments and wounds, founding antiseptic (later aseptic) surgical practice.

Why It Still Matters

Modern sterile technique, skin prep, and OR discipline descend from Lister’s insight that surgical infection is preventable microbial contamination.

Active Recall

  2. How does antisepsis differ from later asepsis?
