A
Liquid Paper (修正液) was invented by Bette Nesmith Graham. She was 17 when she got a job at a Texas bank as a secretary, even though she didn’t know how to type. The company she worked for sent her to a secretary school, and she was typing in no time at all.
The 1950s had seen the widespread use of the electric typewriter, which typed faster but also meant more mistakes. Also, mistakes made by early electric typewriters were very hard to erase, which caused problems for Bette.
