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.
Giovanni Caselli
Father Giovanni Caselli (8 June 1815 – 25 April 1891) was an Italian physicist, inventor and priest. He is the inventor of the pantelegraph (a.k.a. Universal Telegraph or "all-purpose telegraph"), the predecessor of the modern fax machine. The world's first practical operating facsimile machine ("fax") system put into use was by Caselli.
