7 Momentous Inventions Discovered by Accident
7 Momentous Inventions Discovered by Accident Penicillin The world’s first antibiotic, which has prevented millions of deaths from infection and disease, was the accidental byproduct of a messy workspace. Alexander Fleming, a bacteriologist in London, returned from a vacation in 1928 to discover that one of the petri dishes in his lab had mold growing on it— the result of unintended contamination. On closer inspection, he saw that the area around the mold was free of bacteria. Fleming named this bacteria-killing mold juice penicillin after the species of fungus, Penicillium notatum, and published a paper about his discovery in 1929. However, he wasn’t sure if it had any practical use, as it was difficult to purify and stabilize. A decade later, chemists at Oxford University read Fleming’s paper and took up the project of turning penicillin into viable medicine. It was fi...
