He worked aside Alexander Graham Bell to draft the necessary drawings required to receive a patent for the telephone. In 1884, Latimer was hired by Thomas Edison as a draftsman and an expert witness in patent litigation on electric lights. The National Inventors Hall of Fame inductee also co-patented an improved toilet system for railroad. (AP Photo/Steve Miller).
