Andrew Jackson Signed United States Patent.

Rare United States Patent signed by Andrew Jackson as the 7th President of the United States. One page, partially printed, the patent is dated June 22, 1832 and is issued to inventor Henry Koon for a fly net. In the nineteenth century, fly nets were protective mesh coverings designed to shield horses from flies and other biting insects, particularly during the warmer months when insect activity was at its height. In military contexts, fly nets were essential for maintaining the health and readiness of cavalry and transport horses, which were vital to communication, mobility, and supply lines. The document is co-signed by Secretary of State Edward Livingston and Attorney General Roger B. Taney, both of whom played major roles in Jacksonian-era politics. Jackson's signature shows minor ink skipping, and the white paper seal is partially removed, as is typical for documents of this age and format. Four years after this patent was issued, the U.S. Patent Office suffered a catastrophic loss when a destructive fire broke out on the night of December 15, 1836, in Blodgett's Hotel in Washington, D.C., which at that time housed the Patent Office. The blaze destroyed nearly 10,000 patent records and more than 7,000 patent models; indeed, almost all documentation of inventions submitted before 1836 was lost. These early patents, now referred to as “X-Patents,” largely disappeared from the historical record, with only a small number later reconstructed from surviving copies or private records. Consequently, original patent documents from this pre-fire period—particularly those bearing the signature of a sitting president such as Andrew Jackson—are exceptionally rare and historically significant, representing surviving evidence of America’s earliest recorded innovations. In very good condition. Matted and framed with a portrait of Andrew Jackson. The entire piece measures 28 inches by 24 inches. Accompanied by a JSA letter of authenticity.
