by Jason Emerson
"In addition to his other accomplishments, Abraham Lincoln was the only U.S. president to hold a registered patent. Jason Emerson offers the first treatment of Lincoln's invention of a device to buoy vessels over shoals and its subsequent patent in May 1849 as more than a mere historical footnote."--Back cover.
