SEXISM OH NO WAY! Margaret Knight used to work in paper bag factory. She observed that it was tough to pack things into the flimsy, shapeless sacks. So, she went ahead to invent a machine that could fold and glue paper to make a flat-bottomed bag. However, another employee named Charles Annan copied her idea and got a patent for it before she could. Knight sued Annan for copyright infringement wherein Annan argued that since Knight was a woman, she couldn’t be the true inventor. Eventually, Knight’s sketches and detailed plans for the machine won her the case later. She then established her own paper bag company and received large sums of royalties for her invention. #paperbags #inventions #ladyinventors #sexism https://www.instagram.com/p/CL1tH9PF9BK/?igshid=o2b21cz57ia
