Mary Kies Receives First U.S. Patent Issued to a Woman
In early 19th-century New England, straw hat production was a vital cottage industry supporting many households amid trade disruptions from the Embargo Act. Mary Dixon Kies of South Killingly, Connecticut, developed an improved method of weaving straw with silk or thread to create stronger, more attractive bonnets. On May 5, 1809, President James Madison signed her patent, making her the first woman to receive a U.S. patent in her own name. The technique boosted local hat manufacturing and earned praise from First Lady Dolley Madison. Though the original patent document was lost in an 1836 fire, records confirm its issuance and impact on the regional economy.
