Few scientists have had as profound an impact on modern medicine as Joseph Lister. Born in 1827 in Upton, England, and passing away in 1912, Lister is considered the founder of antiseptic surgery, a medical field that has saved millions of lives and completely transformed the way surgical operations are performed. 

A visionary who forever changed surgery

In his honor, the bacterial genus Listeria was named after him, including the pathogenic species Listeria monocytogenes, responsible for serious foodborne infections.

Although today it seems obvious that every operation must take place in a sterile environment, in the mid-19th century things were very different. Surgery was a dangerous and often fatal endeavor, and the causes of postoperative infections were poorly understood. 

At that time, Lister was among the first physicians to recognize the direct link between microorganisms and the infections that appeared after wounds or surgical procedures. Through perseverance, careful observation, and innovative thinking, he opened a new era in medicine—the era of antisepsis.

From a passionate young student to a pioneer of medical science

Joseph Lister began studying medicine at just 17 years old at the University of London. He was fascinated by biology, anatomy, and above all, the mysteries of surgery. 

During his hospital practice, he observed a phenomenon that would occupy his mind for years: patients with open fractures frequently died from infections, while those with closed fractures recovered much better. This difference made him wonder why exposing a wound to air almost always led to infection.

The answer came through the studies of Louis Pasteur, who demonstrated that fermentation and putrefaction were caused by invisible microorganisms present everywhere in the air.

Lister immediately made the connection between Pasteur’s discoveries and the problems he witnessed in the operating room: if bacteria caused putrefaction, they might also be responsible for postoperative infections. It was a revolutionary idea for its time.

The discovery of carbolic acid and the beginning of antisepsis

To put his theory into practice, Lister chose to use carbolic acid, known today as phenol. The substance was already being used in some cities to treat wastewater, since it eliminated unpleasant odors and prevented decomposition. Lister assumed that phenol might have the same effect on the bacteria infecting wounds.

In a bold first experiment, he applied a dressing soaked in a weak solution of carbolic acid to the wound of a patient with an open fracture. The results were astonishing for the time: the wound healed without signs of infection, and the patient survived. Soon, his method began to be applied to other surgical cases, with similar outcomes. Mortality among Lister’s patients dropped dramatically.

It is worth noting that the French pharmacist Lemaire had previously used carbolic acid–soaked bandages, but Lister was the one who transformed the practice into a coherent, scientific system for protecting wounds from bacterial infection. 

He also introduced a strict discipline in the operating room: surgical instruments had to be disinfected before use, surgeons’ hands had to be thoroughly washed, and the work area meticulously cleaned. These seemingly simple practices revolutionized medicine.

Antiseptic spraying – a bold but imperfect idea

In 1871, Lister took an even bolder step. He designed a system for spraying a diluted solution of carbolic acid into the operating room using hand-held devices similar to modern sprayers. 

The goal was to create an “antiseptic mist” that would destroy airborne bacteria and thus provide a sterile environment for surgery. At that time, the idea seemed almost miraculous.

However, this method did not stand the test of time. Although well-intentioned, it proved difficult in practice: the phenolic mist irritated wound tissues, obscured the surgeon’s view of the operation site, and caused severe skin damage to the surgeons’ hands due to prolonged contact with the chemical. 

Lister himself abandoned the spraying technique after a few years, focusing instead on safer sterilization methods.

Even so, his attempt was essential to medical progress. His experiments inspired the use of other, more effective antiseptics such as iodine and mercuric chloride, which later became common worldwide. 

What mattered most was not the exact chemical formula, but the fundamental principle Lister introduced: preventing infection by destroying bacteria.

Joseph Lister’s legacy and his influence on modern medicine

The impact of Joseph Lister’s discoveries is nearly impossible to overstate. Thanks to him, surgery evolved from a perilous, high-mortality practice into a safe and controlled discipline. 

Before Lister, surgeons did not wear gloves, did not sterilize instruments, and had no understanding of microbes. After Lister, handwashing, sterilization, and antiseptic use became universal norms.

Numerous hospitals around the world have been named after him, and generations of doctors have been trained in the spirit of rigor and hygiene that he promoted. Even the term “Listerian” entered medical vocabulary, defining the antiseptic and cleanliness principles inspired by him. 

Beyond the scientific domain, his contribution changed society’s perception of medicine—not merely as the art of healing but as a science grounded in observation, experimentation, and discipline.

Joseph Lister Street – a tribute in an elegant corner of Bucharest

Bucharest, a city rich in history and cultural symbolism, chose to honor Joseph Lister by naming a street after him. It is located in the Cotroceni district, considered by many to be the most beautiful and refined neighborhood in the Romanian capital. 

Cotroceni is a place filled with tradition, elegance, and history, home to interwar villas, prestigious medical institutions, and one of the country’s most renowned medical schools.

Placing “Doctor Joseph Lister Street” in this neighborhood is no coincidence. Cotroceni is a true hub of Romanian medical excellence, hosting the University Emergency Hospital, the National Institute of Legal Medicine, and the “Carol Davila” Faculty of Medicine. 

In this context, Lister’s name perfectly resonates with the spirit of the area—a space dedicated to knowledge, innovation, and respect for life.

The street bearing his name is a symbolic expression of gratitude to a man who, though he had no direct connection to Romania, profoundly changed the lives of everyone, including Romanians. 

Every safe operation, every successful intervention in a Bucharest hospital carries, indirectly, the mark of his legacy.

A legacy that endures

Today, more than a century after his death, Joseph Lister remains a model of dedication and visionary thinking. What set him apart was not only his intelligence but also his courage to challenge the dogmas of his era and to believe in science when others clung to tradition. 

In an age when germ theory was only beginning to take shape, Lister had the intuition to apply it in practice, with spectacular results. His legacy lies not only in antiseptic techniques but also in his attitude toward the medical profession, a combination of rigor, empathy, and innovation. 

The street that bears his name in Cotroceni is not merely an urban landmark; it is a symbol of respect for science, progress, and life itself. It reminds passers-by that, thanks to people like Joseph Lister, modern medicine has become a safe, clean, and profoundly human art.

Ultimately, the story of Doctor Joseph Lister is a lesson in the courage to change the world through science. From his modest English laboratory to the elegant streets of Bucharest, the echo of his discoveries continues to inspire generations of doctors and researchers. 

And perhaps, when walking down the street that bears his name, we should remember that every simple act of hygiene or every safe medical procedure carries within it the spirit of a man who refused to accept death as inevitable—and transformed medicine into a promise of life.
