Margaret Knight was an employee in a paper bag factory in 1868 when she invented a new machine part that would automatically fold and glue paper bags to create square bottoms for paper bags. Paper bags had been more like envelopes before. Margaret Knight's paper bag machine made flat-bottomed paper bags that are still in use today.
