Mary Dixon Kies’s patent was destroyed in the 1836 U.S. Patent Office fire.
By the end of 1836, Mary Dixon Kies’s original patent, along with approximately 10,000 others, was consumed by the devastating U.S. Patent Office fire. This incident eradicated countless documents, posing significant historical and legal challenges. The fire underscored the vulnerability of early efforts in documentation, preservation, and the impermanence of recognition, especially poignant for Kies whose pioneering achievements in the realm of patents were nearly lost to history. This event encapsulates the precarity of early patent records before systematic backup measures were standardized.
