The Discovery of Antibiotics
In the late 1920s, Alexander Fleming stumbled upon penicillin, a discovery that would change medicine forever. Penicillin’s ability to combat bacterial infections such as pneumonia, syphilis, and gangrene saved countless lives, especially during World War II. Following penicillin’s success, the pharmaceutical industry developed numerous other antibiotics, including streptomycin, tetracycline, and erythromycin, which expanded the arsenal against infections.
