Before delving into his groundbreaking scientific work, it is worth acknowledging that Fleming was not just a scientist but also a captain during World War I. This military experience was far from tangential to his career in medicine.

In fact, it deeply influenced his research and fueled his determination to find treatments for infectious diseases that plagued soldiers on the battlefield. It is this blend of military service and scientific exploration that paints a multi-dimensional picture of Fleming’s life.

Of all his achievements, however, Fleming is best known for the discovery of penicillin. In the words of the Nobel Committee, “This achievement called for years of labor, unerring instinct, profound and wide knowledge, teamwork and some luck.”

This introduction sets the stage for a deeper dive into Fleming’s life, his contributions to science, and his enduring legacy. Join us as we explore the fascinating story of this remarkable man and his lasting impact on our world.


1. Fleming’s Military Service

Before he made his groundbreaking discovery of penicillin, Alexander Fleming served in World War I. As a captain in the Royal Army Medical Corps, Fleming was stationed at a makeshift laboratory in Boulogne, France, where he witnessed first-hand the devastating effects of infected war wounds on soldiers.

Fleming’s military service was pivotal in shaping his scientific career. His experiences on the battlefield exposed him to the harsh realities of infection and the limited success of available treatments. This ignited a spark in him to seek out a more effective solution. He noted in his wartime notebook, “I have seen men die from the so-called ‘cures’ rather than from the injuries themselves.”

The urgency and the scale of the problem inspired Fleming. He realized that the existing antiseptics did more harm than good by harming the body’s natural defenses more than the bacteria they were supposed to kill. This understanding led him to start his quest for something better — a substance that could kill harmful bacteria without damaging the human body.

After the war ended, Fleming returned to St. Mary’s Hospital in London. Here, he applied the knowledge gained during his military service to his research. He focused on finding an agent that could effectively kill bacteria without causing harm to the human body, this pursuit led him to his accidental discovery of penicillin in 1928.


2. Discovering Lysozyme

Before the world-changing discovery of penicillin, Alexander Fleming made another significant breakthrough in the realm of bacteriology. This lesser-known but crucial discovery was that of lysozyme, an enzyme with weak antibacterial properties.

Fleming’s journey towards uncovering this enzyme was driven by a relentless pursuit of truth and knowledge, even in the face of initial dismissal from the scientific community.

In 1922, while suffering from a common cold, Fleming noticed that his nasal mucus had an unexpected effect on bacteria. When he transferred some of his nasopharyngeal mucus onto a Petri dish, he observed that it inhibited bacterial growth.

After further research, Fleming identified the component responsible for this antibacterial action as lysozyme. This marked the first step towards his greatest invention.

Lysozyme, as Fleming soon discovered, is not only present in mucus but is also found in various parts of the human body such as fingernails, hair, saliva, skin, and tears. It carries out the important function of protecting these areas from bacterial infections. However, its effectiveness varies, as it is potent against only a small number of non-harmful bacteria.

Despite lysozyme’s limited range of action, its discovery was crucial in shaping the future path of medical science. Fleming’s work with lysozyme sparked his interest in finding more potent antibacterial agents, eventually leading him to the discovery of penicillin.

This journey showed that even seemingly minor observations, like the effect of nasal mucus on bacteria, could lead to major scientific breakthroughs when pursued with curiosity and dedication.


3. The Accidental Discovery of Penicillin

In the realm of scientific discoveries, some are meticulously planned while others happen by chance. One of the most groundbreaking and life-saving discoveries in medical history, the discovery of penicillin, falls into the latter category.

This serendipitous finding by Alexander Fleming in 1928 forever transformed the landscape of medicine, providing a powerful tool to fight bacterial infections.

The Story Behind

As a bacteriologist at St. Mary’s Hospital in London, Fleming was conducting research on the influenza virus. Known for his somewhat careless approach to lab protocol, he departed for a two-week vacation, leaving behind Petri dishes of staphylococcus bacteria cultures.

Upon his return, Fleming found that one of the culture plates had been accidentally contaminated with a mold, later identified as Penicillium notatum. Intriguingly, around this mold growth, the staphylococcus bacteria were being annihilated.


The observation piqued Fleming’s curiosity, leading him to further examine the mold. He found that it released a substance that effectively killed a wide variety of bacteria. This antibacterial substance was penicillin, marking the birth of a new era in medicine. Yet, despite the profound implications of this discovery, it was initially met with skepticism from the scientific community.

Many scientists remained unconvinced about the therapeutic potential of penicillin. They argued that it would be impossible to produce in large quantities, and were concerned about its potential side effects. Nonetheless, Fleming believed in the potential of his discovery and continued his research, even though the road to acceptance was steep.
