<p>Black history inventors are listed alphabetically: Each listing has the name of the black inventor followed by the patent number(s) which is the unique number assigned to an invention when a patent is issued, the date the patent was issued, and a description of the invention as written by the inventor. If available, links are provided to in-depth articles, biographies, illustrations and photos on each individual inventor or patent.
