In 1874, Margaret Knight, an innovative female inventor, revolutionized the paper bag industry by patenting a machine that produced flat-bottomed paper bags. This invention initiated a significant shift in the economic landscape by offering a more efficient alternative to cloth and burlap sacks. While Knight's technology facilitated the widespread use of paper bags, it also led to job losses in communities dependent on traditional bag-making. The introduction of this machine underscored societal challenges in adapting to mechanical advancements.
