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.
Telegraphy
Contrary to the extensive definition used by Chappe, Morse argued that the term "telegraph" can strictly be applied only to systems that transmit "and" record messages at a distance. This is to be distinguished from "semaphore", which merely transmits messages. Smoke signals, for instance, are to be considered semaphore, not telegraph. According to Morse, telegraph dates only from 1832 when Pavel Schilling invented one of the earliest electrical telegraphs.
