He made several inventions of great value, among them the carbon process for making permanent photographs, called autotypes, a miner's electric safety lamp, improvements in electro-metallurgical deposition, but most notable of all the incandescent electric lamp which bears his name, the forerunner of all the electric lamps now in use. These inventions brought him many honors, including a fellowship in the Royal Society.
