7 things you might not know were invented by women
We use some of these things everyday, but we are still unaware of their origin. Let's find out which popular items were invented by talented women you've never heard of.
#1 Mary Anderson – the first operational windshield wiper
When Mary got home, she hired a designer and started working on this. The same year, she was granted a 17-year patent for a windshield wiper. It consisted of a rubber blade that was operated by the lever inside the vehicle. Anderson's invention became the first one of the kind to be effective.
#2 Margaret E. Knight – the flat-bottomed paper bag
A man named Charles Annan tried to steal Knight's invention: he saw the concept, built the similar machine and even patented it. In 1871, Margaret filed a lawsuit and was awarded the patent. Except that, Margaret invented many other useful devices, including a numbering machine, lid removing pliers, and a window frame and sash.
#3 Josephine Cochrane – the dishwasher
#4 Tabitha Babbitt – the circular saw
#5 Lizzie Magie – Monopoly
Four versions of the game published by Magie were a success with left-wing academics, but only the monopolistic version became popular among the general public. 30 years later, an inventor named Charles Darrow altered the board and sold his version to Parker Brothers. They bought Magie's patent for the game for $500 and no royalties. They promised to continue to produce Magie's anti-monopolist original game, but never did.
#6 Bette Nesmith Graham – liquid paper
#7 Jeanne Villepreux-Power – Aquarium
