Many antibiotics wouldn’t exist if this hadn’t been discovered
Medical science has come a long way. Back in the day, you could die from strep throat. Fortunately, a man known as Alexander Fleming made a huge breakthrough in his lab and revolutionized the antibiotics industry for good.

Fleming discovered Penicillin, a life-saving antibiotic capable of fighting dangerous bacteria. Its effect was most apparent on the battlefield; while nearly 20% of soldiers with bacterial pneumonia died in World War I, only 1% suffered the same fate during World War II, thanks to his invention.
