Although his discoveries were undervalued and even ridiculed during his lifetime, his work saved countless lives and laid the foundation for antiseptic practices in hospitals.
Today, it’s hard to imagine anyone not washing their hands before eating or after using the restroom. It’s even more inconceivable to think of a doctor neglecting to wash their hands before treating another patient, performing surgery, or assisting in childbirth. Handwashing has become such a fundamental part of hygiene that we don’t even think about it—it’s just a basic habit. Yet, just two centuries ago, something as simple as washing hands was either entirely ignored or considered unnecessary.
In hospitals, it was common for doctors to move between the morgue and the maternity ward without stopping to wash their hands. At the time, there was no scientific understanding that invisible microorganisms could transmit deadly infections. This seemingly small step—making handwashing mandatory—represented one of the greatest leaps in health protection and continues to save millions of lives each year.
Semmelweis, a Pioneer of Medical Hygiene
Ignác Filip Semmelweis, a Hungarian physician born on July 1, 1818, in Buda, is still regarded as one of the pioneers of modern medical hygiene. Although his discoveries were undervalued and even mocked during his lifetime, his work saved countless lives and laid the foundation for antiseptic practices in hospitals. What were his contributions, and why should his name be remembered?
In the 1840s, Semmelweis worked at Vienna General Hospital, where he observed an alarming phenomenon: the high mortality rate of women dying from puerperal fever (childbed fever). At the time, it was one of the greatest dangers women faced during childbirth. Compared to wards attended by midwives, the mortality rate on the medical ward was significantly higher. Why? This question led Semmelweis to his revolutionary discovery—one that might seem trivial today but was anything but at the time.
The whole of Vienna was aware of the high maternal mortality rate at the First Medical Clinic. In his writings, Semmelweis described the terror of women who, fearing death, often begged to be discharged, knowing that medical treatment often foretold their demise. Despite the fear, many women continued to seek treatment at the clinic because it offered free care for the poor and the opportunity to leave their child in the hospital’s care after birth. This was especially appealing in 1847 Vienna, where half of all children were born out of wedlock.
The Discovery of a Simple but Crucial Measure
On the first ward of the medical faculty, autopsies were frequently performed—Semmelweis himself conducted them daily. Doctors and assistants who handled corpses would then examine women and make rounds without washing their hands. Semmelweis realized that the high maternal mortality rate was caused by contact with cadavers. He also noticed that physicians and medical students often entered the maternity ward directly from the morgue without adequately washing their hands.
His suspicion that infections originated in the hospital was confirmed by the death of his colleague Jakob Kolletschka, who succumbed to sepsis after being injured with a scalpel during an autopsy. Kolletschka’s symptoms mirrored those of women suffering from puerperal fever. As a result, Semmelweis implemented strict handwashing protocols using a chlorinated lime solution before examining patients.
Semmelweis, of course, had no knowledge of bacteria at the time; he referred to “decayed organic matter.” The most distressing realization for him was that doctors themselves, including him, were the ones transmitting infections from deceased bodies to living patients. The unpleasant smell lingering on hands after autopsies provided further evidence. Chlorine solutions were most effective at removing this smell, so Semmelweis mandated their use. The results were immediate: mortality rates from puerperal fever plummeted from over 10% to just 1–2%.
This was one of the first confirmations that infections could be spread by microorganisms, even though germ theory was still in its infancy.
Semmelweis, an Unappreciated Advocate for Science
Despite the overwhelming success of his methods, Semmelweis faced significant resistance from his colleagues. Many were unwilling to accept the idea that doctors could be the cause of deadly infections. Frustrated and increasingly isolated, Semmelweis’s health deteriorated, and his relentless fight for hygiene in medicine cost him his peace of mind. He died on August 13, 1865, in a Viennese asylum, ironically succumbing to the very type of infection he had spent his life combating.
It wasn’t until the development of microbiology in the 1870s, through the work of Louis Pasteur and Joseph Lister, that Semmelweis’s ideas gained widespread recognition. The hygienic measures he advocated became the foundation of modern medicine. Today, Ignác Semmelweis is remembered as the “savior of mothers,” whose fight for hygiene marked a monumental shift in patient care.
The Legacy of a Pioneer
Semmelweis’s most significant contribution was his early formulation of antiseptic principles, including the importance of hand disinfection to prevent disease transmission. These practices only became standard hospital protocol after his death.
Semmelweis’s name lives on in institutions such as the Semmelweis University in Budapest and museum exhibits dedicated to his life. In times of pandemics and infectious disease outbreaks, his work remains highly relevant, reminding us of the critical importance of hygiene and health protection.
Ignác Filip Semmelweis serves as an inspiration not only to doctors but also to anyone who believes in the value of truth and science, even when recognition is slow to come. His story demonstrates how even the simplest discoveries—like washing hands—can have revolutionary effects on human lives.
