1879: Saccharin, the artificial sweetener, is discovered by Constantin Fahlberg while researching coal tar compounds at Johns Hopkins University in Baltimore, Md. The sweet taste of saccharin was discovered when Fahlberg noticed a sweet taste on his hand during a meal and connected the incident with the compound he had been working on that day. He subsequently became wealthy by establishing a factory to produce it.
