It was an accidental finding on September 3, 1928, wherein one on his fungus contaminated staphylococci culture destroyed all the surrounding staphylococci culture while other staphylococci colonies somewhat away were normal. The antibiotic eventually came into use during World War II, revolutionizing battlefield medicine and, on a much broader scale, the field of infection control. In the quest of finding its effect on the bacterial growth, he mixed it and studied for a few days, thus leading to this significant discovery for mankind.

Additionally, Fleming served as president of the Society for General Microbiology, a member of the Pontifical Academy of Science, and an honorary member of nearly every medical and scientific society in the world. Alexander married Susannah Fleming. He worked as a bacteriologist, studying wound infections in a makeshift lab that had been set up by Wright in Boulogne, France. Fleming decided to investigate further, because he thought that he had found an enzyme more potent than lysozyme. Wright and Fleming advocated that the antiseptics were preventing the healing process and that a sterile saline solution was the better alternative. CBS News. He was inspired to further experiment and he found that a mould culture prevented growth of staphylococci, even when diluted 800 times.
