SACCHARIN
In 1878, Dr. Ira Remsen and his postdoctoral student Constantin Fahlberg were working on various products derived from coal tar. One night, Fahlberg worked late in the lab and went home to take supper in a hurry, neglecting to wash his hands. while eating, he realized that the bread he ate was unusually sweet, and so was his drink. Eventually Fahlberg realized that he was sipping his drink from an area of his cup his fingers touched. He tasted his thumb, and then ran back to the laboratory to work on the newly discovered accidental blessing “coal tar sugar,” which he named saccharin.
