Henry Renno Heyl (1842–1919) was an American inventor and chemist known for his contributions to early motion picture technology and office equipment. He invented the phasmatrope, an early device for projecting moving images, and received the first United States patent for a stapler. Despite his innovations, Heyl received limited recognition during his lifetime, with many of his ideas overshadowed by later commercial developments.
