📜 On this day in 1809
Mary Kies became the first woman in the U.S. to receive a patent, for her silk & thread hat-weaving method.
Her original patent was lost in an 1836 fire, but her legacy endures in museums & monuments.
#OnThisDay #WomenInInnovation #PatentHistory
🗓️ On this day in history — May 5, 1809 Mary Kies became the first woman in the United States to be awarded a patent, for her innovative method of weaving straw with silk and thread to make hats. 👒🧵 Her invention was both practical and groundbreaking — boosting domestic hat production at a time when imported goods were heavily restricted. While her original patent document was lost in the tragic 1836 U.S. Patent Office fire 🔥, Kies’s contribution to both women’s history and industrial innovation remains commemorated through museum exhibits and monuments in Connecticut. 🏛️ Sample textiles of her invention are preserved at Wadsworth Athenaeum and Danielson Public Library. 📍 South Killingly honors her with a public memorial. As we reflect on the role of women in invention and entrepreneurship, Mary Kies reminds us how powerful a single idea — and the courage to claim it — can be. #OnThisDay #PatentPioneer #WomenInSTEM #InnovationHistory #SustainableTextiles #FashionTech #DODOTributes 🗓️ On this day in history — May 5, 1809 Mary Kies became the first woman in the United States to be awarded a patent, for her innovative method of weaving straw with silk and thread to make hats. 👒🧵 Her invention was both practical and groundbreaking — boosting domestic hat production at a time when imported goods were heavily restricted.
