Joseph Lister used carbolic acid to kill germs in wounds and operating rooms, sharply reducing deaths from surgical infection.
See it on the Technology & Medicine map →How it works
Even after anesthesia, many surgical patients died of wound infection, then called 'hospitalism'. Reading Pasteur, Glasgow surgeon Joseph Lister reasoned that germs caused it. On August 12, 1865, he dressed 11-year-old James Greenlees's open fracture, with bone through the skin, using carbolic acid; it healed. He then cleaned instruments, hands and wounds, and later sprayed carbolic mist. Amputation deaths on his wards reportedly fell from about 45% to 15%.
Why it mattered
With anesthesia, antisepsis made surgery usually survivable, and it led to today's sterile, 'aseptic' operating room.
How we know
His 1867 Lancet papers, ward statistics and case notes; adoption came faster in Germany than in Britain or America. Listerine mouthwash (1879) borrowed his name.
Still unknown or debated
His mortality figures came from small numbers amid other ward changes, so the exact size of the improvement is debated.
Connections (3)
▸Surgical anesthesia (ether) was complemented by Lister's antiseptic surgeryMostly agreed
The connection
Anesthesia made surgery painless, so surgeons operated more often and for longer. But open wounds in crowded wards often became infected, and amputation deaths stayed high, perhaps a third to a half in some hospitals. Lister's antisepsis tackled that second killer, and together the two made modern surgery possible.
When and how
Boston, 1846 (ether); Glasgow, 1865 (Lister); both spread internationally over the following years and decades.
How sure are we?
Hospital statistics, such as James Young Simpson's 1869 surveys of amputation deaths, which he called 'hospitalism', show infection as the main killer after surgery.
Debates and open questions
Whether anesthesia actually raised infection deaths for a time, by encouraging more and longer operations, is debated by historians.
▸Louis Pasteur inspired Lister's antiseptic surgeryWell documented
The connection
In 1865 Lister read Pasteur's papers showing that microbes from the air cause putrefaction. He reasoned that wound infection was the same process, so killing germs in and around the wound with carbolic acid should prevent it. He credited Pasteur openly and wrote to thank him in 1874.
When and how
Glasgow, 1865, after chemistry professor Thomas Anderson pointed Lister to Pasteur's work.
How we know
Lister's 1867 Lancet papers cite Pasteur, and his 1874 letter thanking Pasteur survives.
Debates and open questions
Lister focused on airborne germs, but hands and instruments mattered more; how this emphasis shaped methods like his later-abandoned carbolic spray is discussed.
▸Ignaz Semmelweis and handwashing was vindicated by Lister's antiseptic surgeryMostly agreed
The connection
Both men used chemical disinfectants to stop infection: Semmelweis chlorinated lime on hands, Lister carbolic acid on wounds and instruments. Lister's success, explained by germ theory, made Semmelweis's rejected idea look prophetic. Lister said he had not known Semmelweis's work at first, but later praised him as a forerunner.
When and how
Vienna, 1847, and Glasgow, 1865; Semmelweis died in an asylum the year Lister began.
How sure are we?
Lister's later statements acknowledging Semmelweis; the two worked independently, so the link is vindication rather than influence.
Debates and open questions
Whether wider knowledge of Semmelweis's data would have sped up antisepsis is unknowable; how far Lister knew of other forerunners is unclear.
