In 1879, a chemist named Constantin Fahlberg sat down to dinner without washing his hands after a day spent handling coal tar. His bread tasted strangely sweet. So he went back to the lab and started tasting everything on his bench until he found the source. That was saccharin, the first artificial sweetener, discovered because a man would not wash his hands before dinner.
