Louis Braille invented braille in 1821. He got the idea from Charles Barbier when Napoleon demanded that Barbier invent a code that the soldiers could use at night to communicate without the use of light. It was too complicated and the Army no-no’ed it but later he met Louis Braille and that’s how braille came to be.
In 1930, Ruth Wakefield put pieces of chocolate bars into her cookie recipe to serve to her guests. The chocolate softened but stayed as small pieces, not spreading out. They went over well and the maker of the chocolate bar, Nestle, decided to incorporate them into her recipe and that’s how the Nestle Toll House Cookie came to be.
