Patent model and application submitted by Abraham Lincoln, "Method of Buoying Vessels over Shoals," 1849
The only American president to receive a patent, Lincoln came up with this idea in 1848, a result of being stranded on sandbars during his boat travels. Although his device was never manufactured, Lincoln held a life-long interest in technology and the inventive process. The Smithsonian acquired this model from the Patent Office in 1908.
