Born in 1881 in Scotland, Alexander Fleming's early life was marked by a passion for science. He pursued his education at the Royal Polytechnic Institution in London, where he developed a keen interest in bacteriology. After graduating, he joined the prestigious St. Mary's Hospital Medical School, where he would later make his groundbreaking discovery. Fleming's early research focused on the development of vaccines and the study of bacterial infections, laying the foundation for his future contributions to medicine.

In 1928, while working in his laboratory at St. Mary's Hospital, Fleming made a chance observation that would change the course of medical history. He noticed that a mold, later identified as *Penicillium notatum*, had contaminated a petri dish containing staphylococcus bacteria. The mold had created a clear zone around it, where the bacteria had been killed. This serendipitous discovery led Fleming to isolate the active substance produced by the mold, which he named penicillin.
