In 1814, Mary Kies became one of the first women in the United States to receive a patent, marking a significant milestone for female inventors. Her innovation, which involved weaving straw with silk or thread, revolutionized hat-making, a key sector in the fashion industry. This method not only energized the millinery business but also helped revitalize the New England economy. Kies's pioneering work encouraged more women to participate in the patent system, setting a legacy for female inventorship.
