Bette Nesmith Graham was a secretary but always wanted to be an artist. When she made mistakes she would use some tempera water based paint to correct her mistakes. It was an instant success with her fellow secretaries and everybody wanted to buy some from her. She used her kitchen as a laboratory to improve the product using mostly her electric blender.
The product was so good that her boss never noticed she was using any of the then called “Mistake Out”. The only day she couldn’t fix her mistake she got fired. This allowed her to focus only on her new business called “Liquid Paper”. By 1967, it had grown into a million dollar business. Graham died in 1980, six months after selling her corporation for $47.5 million. Her son, Michael Nesmith was the drummer of the famous band “Monkees” and the inventor of MTV.
