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.
George Parker Bidder
He was "one of the first to recognize the value of the electric telegraph." That invention was in its infancy when, in 1837, jointly with R. Stephenson, he recommended its introduction on a portion of the London & Birmingham and on the Blackwall lines, while three years later he advised that it should be adopted to facilitate the working of the single line between Norwich and Yarmouth. He was also one of the founders of the Electric Telegraph Company, which enabled the public generally to enjoy the benefits of telegraphic communication.
