Description: Like many people of his era, Lincoln believed deeply in the value of personal initiative, inventiveness, and scientific and technological change. Lincoln’s mechanical and scientific interests began with his training as a surveyor in New Salem and continued throughout his life.
Description: In 1848 he decided try his own hand at developing an invention to lift boats grounded in shallow water. On May 22, 1849, Congressman Abraham Lincoln received a patent for his method of lifting boats over shoals. A trip to Niagara Falls inspired the design, when he witnessed a grounded boat being lifted over shallow waters. Lincoln produced the model with the help of Walter Davis, a Springfield mechanic. There is no evidence that he ever sought to put the idea into production.
Description: Transfer from the U.S. Patent Office, 1922
