Did You Know?

The inventor of Vaseline used to eat a spoonful of it every day.

Robert Augustus Chesebrough, was an American chemist. He discovered petroleum jelly which he marketed as Vaseline and he founded the Chesebrough Manufacturing Company.
Chesebrough's success stemmed from firm belief in his product. Before Chesebrough began selling petroleum jelly, he tested it on his own cuts and burns. 

Having demonstrated the product's efficacy on himself, Chesebrough was still unable to sell any to drug stores until he travelled around New York State demonstrating his miracle product. In front of an audience he would burn his skin with acid or an open flame, then spread the clear jelly on his injuries while demonstrating past injuries, healed, he claimed, by his miracle product.

Chesebrough lived to be 96 years old and was such a believer in Vaseline that he claimed to have eaten a spoonful of it every day. He died at his house in Spring Lake, New Jersey. He also, reportedly, during a serious bout of pleurisy in his mid-50s, had his nurse rub him from head to foot with the substance. He soon recovered.
