Edmond Charles Genet’s “Aeronaut” - a “Fish-shaped, horse-powered, paddle-wheel dirigible”. This is believed to be the first U.S. patent issued for an aeronautical invention, though it appears the documentation has been lost in time

It appeared in his book of 1825 titled “Memorial on the upward forces of fluids, and their applicability to several arts, sciences, and public improvements”

“From a scientific viewpoint this is the most important American publication in the field of aviation, for it is the first printed suggestion of the correct theory of the heavier than air machine..”
