Joseph Lister & Antiseptic Surgery: Glasgow's Gift to Every Operating Theatre on Earth

Surgery Before Lister

Before Lister, an operation was a gamble with death that had nothing to do with the surgeon's skill with a knife. Anaesthesia, introduced by the Edinburgh obstetrician James Young Simpson with chloroform in 1847, had abolished the agony of surgery. It had not made surgery safe. In the great Victorian hospitals of London, Paris, Vienna and Glasgow, between a third and a half of all major operations ended in the patient's death — not from the knife, but from what followed: gangrene, erysipelas, pyaemia, septicaemia, the catch-all “hospital diseases” that surgeons accepted as the unavoidable price of their craft.

Surgeons operated in frock coats stiffened with old blood; dried pus on the lapels was, absurdly, a badge of experience. Instruments were wiped between patients on the same cloth apron. Ligatures were sometimes held in the surgeon's own mouth. Wards stank of putrefaction, and the presence of “ laudable pus” around a wound was held, in an inversion that seems horrifying now, to be a healthy sign. At Glasgow Royal Infirmary, where Lister took up his Regius chair in 1860, mortality after compound fractures and amputations sometimes ran above 60 per cent.

Nobody had a workable explanation. The dominant theory blamed “miasma” — foul air rising from decaying matter. Others whispered of contagion, without being able to say how it spread. Even James Syme, Lister's own father-in-law and the most admired operator in Britain, confessed that surgeons were essentially powerless against it. Surgery, in the grim phrase of the day, had run into a wall of putrefaction.

Pasteur's Germ Theory, and the Debt Lister Owed

The answer arrived from Paris, and Lister said so, repeatedly and without embarrassment. In 1864 Thomas Anderson, a colleague at the University of Glasgow's chemistry department, drew his attention to the recent work of Louis Pasteur. Pasteur had shown that fermentation and putrefaction were not spontaneous chemical processes in dead tissue, as had been almost universally assumed, but the work of living microscopic organisms carried through the air. Sterilise the environment, and decay stopped.

Lister read Pasteur's papers in the original French, repeated the key experiments at his own bench in Glasgow, and saw what no other surgeon had yet seen: if Pasteur was right, the suppuration that killed his patients was not chemical inevitability but infection — a biological attack on the wound by organisms that could, in principle, be destroyed. This is the intellectual debt at the heart of the discovery, and it should be stated as clearly as any Scottish contribution: without Pasteur's germ theory, there is no Listerian antisepsis.

The remaining problem was practical — with what could a wound be sterilised without poisoning the patient? Lister had read that the town council of Carlisle had successfully treated its sewage with carbolic acid, a coal-tar distillate that killed the smell and, it was suspected, the organisms producing it. If carbolic could sterilise sewage, he reasoned, it might sterilise a wound.

James Greenlees, 12 August 1865

On the afternoon of 12 August 1865, an eleven-year-old boy was brought into Ward 24 of Glasgow Royal Infirmary with a compound fracture of the left tibia. James Greenlees had been run over by the wheel of a cart in the city's High Street. The bone had punctured the skin, and in 1865 a compound fracture was close to a death sentence: the conventional response was immediate amputation, and even then perhaps half of such patients died of infection within weeks.

Lister did something no surgeon had done before. He cleaned the wound with carbolic acid. He wrapped it in lint soaked in carbolic, covered the lint with tinfoil to prevent evaporation, splinted the leg, and changed the dressing at intervals. Then he waited.

The wound did not suppurate. There was no gangrene, no fever, no blood-poisoning. After six weeks the bone had united cleanly, and the boy walked out of Glasgow Royal Infirmary alive. Lister, with the caution of the scientist he was, went on to treat ten further compound fractures over the following two years. Nine survived; the one death was caused by haemorrhage, not infection. On the ordinary Glasgow figures of the day, those eleven patients would have produced six or seven corpses.

In March 1867 Lister published the case of James Greenlees and his successors in The Lancet, under the title “On a New Method of Treating Compound Fracture, Abscess, etc., with Observations on the Conditions of Suppuration”. Months later came the great theoretical statement, “On the Antiseptic Principle in the Practice of Surgery”. Together these are the founding documents of modern surgery — and they report work carried out not in London, Paris or Vienna, but in Glasgow. Across his Glasgow wards as a whole, Lister documented a fall in post-operative mortality from roughly 46 per cent before antisepsis to roughly 15 per cent after it: the largest single improvement in surgical safety yet recorded.

How Antiseptic Surgery Worked

Lister's system rested on a single, almost philosophical insight: the surgeon's enemy is invisible. If Pasteur's microbes caused putrefaction, the wound had to be sealed against them, in three layered ways. First, the wound itself was cleansed with a solution of carbolic acid. Second, every instrument, ligature and dressing that came near it was soaked in carbolic. Third — and most controversially — the air above the operating field was filled with a fine carbolic spray, generated by a hand-pumped brass apparatus that became, for a generation, the visual symbol of Listerian surgery.

The carbolic spray was eventually abandoned, since it poisoned the surgeons more reliably than the germs it was meant to kill, but the underlying principle survived intact: sterilise the wound, sterilise everything that touches it, keep the microbes out, and let the body's own capacity to heal do the rest. In time the chemical antisepsis of carbolic gave way to the steam-sterilised, white-tiled, white-gowned asepsis of the twentieth-century operating theatre — but every gown, every glove, every autoclave descends in a direct line from Lister's Glasgow ward.

Myth vs Evidence: Semmelweis and the Question of Priority

This is not a case that should be papered over for patriotic comfort, and it is worth setting out with the same care given to the shared credit between Frederick Banting, Charles Best and John Macleod for insulin. Semmelweis worked in one of Vienna's two maternity clinics, where mortality from puerperal fever was far higher than in the other; he correctly reasoned that doctors and students were carrying infectious material from autopsies to delivering mothers on unwashed hands, and instituted a strict regime of hand-washing in chlorinated lime. Mortality in his clinic fell dramatically. This is a real, independently verified, and earlier demonstration that a form of antisepsis could save lives.

It is not, however, straightforwardly the same discovery as Lister's, for several reasons that matter to an honest account. Semmelweis worked in obstetrics, treating the transmission of infection between individuals through contaminated hands, rather than in general surgery, where Lister addressed infection of an open surgical wound by microbes in the air, on instruments and on dressings. Semmelweis had no germ theory available to him — he attributed the effect to vague “cadaverous particles” rather than living organisms, and could not explain his own results in terms later science would vindicate. His findings met fierce resistance from the medical establishment of his day, were never systematised into a generalisable surgical method, and were essentially unknown to Lister when he began his own work; Semmelweis himself died, largely unrecognised, in 1865, the same year as the Greenlees operation. Lister's achievement, by contrast, rested explicitly on Pasteur's germ theory, was documented in a published case series, was accepted and adopted by the international surgical profession within two decades, and directly founded the discipline that followed.

The fair and accurate summary, then, is this: Semmelweis showed, years earlier and in a specific obstetric context, that a form of antisepsis worked, without being able to explain why or persuade his peers. Lister showed why it worked, generalised it into a scientific surgical system grounded in germ theory, and persuaded the world. Both deserve their place in the history of medicine; neither claim should crowd out the other.

Return to Edinburgh — Teaching a Generation

In 1869, on the retirement of his old teacher and father-in-law James Syme, Lister was appointed Professor of Clinical Surgery at the University of Edinburgh and took charge of the surgical wards of the Royal Infirmary of Edinburgh. For eight years he taught antiseptic surgery to crowded classes of medical students drawn from across the British Empire and beyond. Edinburgh, already the most famous medical school in the world, became the school of antiseptic surgery, and through its graduates the method born in Glasgow spread to every continent.

His Edinburgh students included figures who would themselves shape the future of surgery: Sir Hector Cameron, Sir William Macewen — who succeeded Lister at Glasgow and pioneered brain surgery — and John Stewart, who carried Listerian method to Canada. When Lister finally moved south to King's College London in 1877, he left behind in Scotland a doctrine, a method and a generation of disciples. By the end of the 1880s no respectable surgeon anywhere in the world operated without some form of antisepsis.

Legacy — From Glasgow to Every Operating Theatre on Earth

Lister's legacy is the modern operating theatre itself. Every sterile field, every autoclaved instrument, every gloved hand and masked face, every drape of green cloth around a surgical site is the working-out of the principle he established in Glasgow in 1865. The discipline of surgical asepsis, perfected at the end of the nineteenth century by surgeons such as Ernst von Bergmann in Berlin and William Halsted in Baltimore, did not replace Lister's antisepsis — it grew directly out of it.

His personal honours were unprecedented for a surgeon. He was created a Baronet in 1883 and, in 1897, Baron Lister of Lyme Regis — the first British medical practitioner ever raised to the peerage. He served as President of the Royal Society from 1895 to 1900 and was a founder member of the Order of Merit at its creation in 1902. The Lister Institute of Preventive Medicine in London, the bacterial genus Listeria, and the antiseptic mouthwash Listerine all carry his name.

But the truest monument is statistical. Before 1865, perhaps a third to a half of all major surgical patients died of infection. Today, the post-operative infection rate in a modern hospital is well under one per cent. Every one of the hundreds of millions of operations performed in the world each year is carried out under sterile conditions descended from what Joseph Lister, an Englishman working at Glasgow Royal Infirmary and the University of Edinburgh, established in a single Scottish ward in the summer of 1865.

Did You Know?

• The mouthwash Listerine and the bacterial genus Listeria are both named after Joseph Lister — though he had no hand in either.
• Lister's carbolic spray was eventually abandoned because it poisoned the surgeons more reliably than it killed the germs, but the principle behind it survived.
• Lister was the first British medical practitioner ever raised to the peerage, becoming Baron Lister of Lyme Regis in 1897.
• His father-in-law and teacher, James Syme, held the same Edinburgh chair Lister would later occupy, and was the most admired operating surgeon in Britain.
• Sir William Macewen, Lister's Glasgow disciple, went on to pioneer brain surgery — a further Scottish first that grew directly out of the Listerian school.
• Lister's father, Joseph Jackson Lister, was an amateur optician whose work on achromatic microscope lenses helped make possible the very science of cell biology that underlay germ theory.

Notes on the Evidence

This article treats Lister's 1865–1867 Glasgow work as the founding demonstration of antiseptic surgery as a generalisable, scientifically grounded system, on the strength of his published case series in The Lancet and its rapid international adoption. It treats Semmelweis's 1847 Viennese hand-washing regime as a genuinely earlier and independently verified reduction in fatal infection, in a different clinical context and without an accompanying germ theory, and states this plainly rather than minimising it. Mortality figures for Lister's Glasgow wards (approximately 46 per cent falling to approximately 15 per cent) are those reported in his own published accounts and repeated in subsequent medical-historical scholarship; as with most nineteenth-century hospital statistics, exact denominators vary between sources, and the figures should be read as Lister's own documented record rather than an independently audited modern dataset. Lister's birthplace, dates, appointments and honours are drawn from standard biographical and Royal Society sources.
