Bette Nesmith Graham
As electric typewriters came into widespread use after World War II, Bette Nesmith Graham and countless other secretaries let out a collective groan. The new machines did make typing easier, but their carbon-film ribbons made it impossible to correct mistakes neatly with a pencil eraser. As a result of this predicament, Graham ended up inventing one of the most widely used office products of the 20th century.

The impetus for Graham's breakthrough came as she observed painters decorating the bank windows for the holidays. Rather than remove their mistakes entirely, the painters simply covered any imperfections with an additional layer. The quick-thinking Graham mimicked their technique by using a white, water-based tempera paint to cover her typing errors.
When the other secretaries realized how well the invention worked, they flooded Graham with requests for their own supplies. The now-famous woman inventor sold her first batch of "Mistake Out" in 1956, and soon she was working full-time to produce and bottle it from her North Dallas home. Her son Michael – who would later achieve fame as a member of the pop group The Monkees – and his friends helped to fill the growing number of orders for Mistake Out.
Graham continued experimenting with the makeup of the substance until she achieved the...
