Antibiotics were discovered by Alexander Fleming in 1928 when he observed that the mold Penicillium notatum produced a substance that killed bacteria. This groundbreaking discovery led to the development of penicillin, the first widely used antibiotic, which revolutionized medicine and the treatment of bacterial infections. Fleming's work laid the foundation for the discovery and development of many other antibiotics in the following decades.
