Dr. Emanuel Bronner was a master soap maker, self-proclaimed rabbi, and, allegedly, Albert Einstein's nephew. In 1947, after escaping from a mental institution, he invented the formula for "Dr. Bronner's Magic Soap," a peppermint-infused, all-natural, multi-purpose liquid that can be found today in every American health food store. On each bottle of his soap, he printed an ever-evolving set of teachings he called "The Moral ABC," designed, in his words, "To unite all mankind free!"
