While we don’t spend very much time in school learning about female inventors that doesn’t mean many of them haven’t made significant contributions to the way we live. Even during times when women’s rights were limited and women in the workplace were hardly imaginable, the great minds of female inventors were still at work. Though they may not always get the credit, history cannot be rewritten to keep these ingenious women out of the books.
The United States got a new paper bag when a cotton mill worker named Margaret Knight created a machine to make square bottom paper bags back in 1868. Another inventor named Charles Annan saw Knight’s design and attempted to patent the concept first. The woman lodged a lawsuit, and in 1871 won the patent.
