Lincoln the Inventor

I went to Jason Emerson's lecture on his new book, "Lincoln the Inventor," yesterday at the National Archives. He focused on a device Lincoln invented to buoy vessels over shoals, or more simply, "a system to get a boat unstuck from a sandbar." Lincoln was the only U.S. president ever to hold a patent. After his lecture Emerson gave me a copy of his book and signed it for me.
