Alexander Fleming
Ayrshire (1881-1955)
Alexander Fleming, a Scottish scientist whose accidental discovery changed the face of medicine forever. From his humble beginnings in Ayrshire, Scotland, to his ground-breaking revelation at St. Mary's Hospital Medical School in London, Fleming's journey embodies the spirit of scientific curiosity and perseverance.
In 1928, amidst Fleming's study of bacteria, a chance encounter with a peculiar mould called Penicillium notatum left him astounded. This seemingly insignificant mould would become the catalyst for a medical revolution. In a stroke of brilliance, (or luck), Fleming uncovered that the mould released a substance capable of inhibiting the growth of the notorious Staphylococcus aureus bacteria which can cause serious infections, leading to sepsis or death if enters the bloodstream.
Dubbed "penicillin" by Fleming, the discovery held tremendous promise. Yet, the road to harnessing its power was filled with challenges. Limited resources hindered his efforts to isolate and purify the compound, but Fleming's unwavering determination propelled him forward. By the 1940s, penicillin was successfully produced on a large scale, marking a turning point in the battle against bacterial infections.
The impact of Fleming's finding cannot be overstated. With the introduction of penicillin, a new era of antibiotic therapy emerged. It proved instrumental in saving countless lives during World War II and its aftermath, and its efficacy continues to this day in the treatment of diverse bacterial infections.
Despite Fleming’s discovery coming almost 20 years prior, he was eventually recognised and was awarded the Nobel Prize in Physiology or Medicine in 1945. Furthermore, he devised innovative techniques for sterilising medical instruments, elevating the standards of medical care, paving the way for modern sanitation practices.

A lesser-known detail is that he also painted using bacteria. Fleming painted ballerinas, houses, and soldiers amongst other illustrations, producing these paintings by growing microbes with different natural pigments in the spaces where he wanted different colours to be. The paintings are said to be technically very difficult to make as he had to ensure the different species all matured at the same time, with these works only existed if one species grew into the others.
Alexander Fleming's accidental encounter with the mould that spawned penicillin has shaped the world we live in. His perseverance, curiosity, and dedication to advancing medical science continue to inspire generations of researchers. We acknowledge that Fleming's legacy will forever remain etched in the pages of medical history.
