Mary Dixon Kies was the first woman to apply for and receive a U.S. patent in her own name. Her patent, issued May 5, 1809, was for a process for weaving straw with silk that was adopted by the New England hat-making industry.

Invention Impact

Kies’s invention was praised by President James Madison's wife Dolly for helping to improve New England's economic situation, which had been hurt by an embargo on goods imported from Europe. New England's hat industry was one of the few industries that continued to prosper during the War of 1812.

Kies's patent, which was destroyed in the Patent Office fire of 1836, was one of only 20 issued to a woman before 1840
