Did you know that you do not have to be a chemist to invent something? An example of chemistry invention that was made by a non-scientist is Liquid Paper. In 1952, a divorced woman named Bette Nesmith Graham needed to work to support herself and her son. Life was very difficult for a single mother. [1] She soon found a job as a typist, but she was not very good at it. [2] She made a lot of errors typing leading her to formulate a white tempura paint to hide them. [3] Using her kitchen as a laboratory, she developed a liquid that other people wanted to buy and use. She named this liquid “Mistake Out” [4]While continuing to work as a secretary, she educated herself in business methods, promotion, and research until she was satisfied that the product she had developed was really worthwhile. Sometimes around 1952 she offered “Mistake Out” to IBM, which turned it down. From 1952 until 1979 she continued to make and sell “Mistake Out”, now renamed “Liquid Paper”, out of her home. In 1979, the Gillette Corporation bought “Liquid Paper” for $47.5 million dollars plus royalties.
