Samuel Morse
In addition to the telegraph, Morse invented a marble-cutting machine that could carve three-dimensional sculptures in marble or stone. He could not patent it, however, because of an existing 1820 Thomas Blanchard design.
Alexander Bain (inventor)
Bain's and Bakewell's laboratory mechanisms reproduced poor quality images and were not viable systems because the transmitter and receiver were never truly synchronized. In 1861, the first practical operating electro-mechanical commercially exploited telefax machine, the Pantelegraph, was invented by the Italian physicist Giovanni Caselli. He introduced the first commercial telefax service between Paris and Lyon at least 11 years before the invention of workable telephones.
