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.
Claude Chappe
Chappe first called his invention the "tachygraph", meaning "fast writer". However, the Army preferred to use the word "telegraph", meaning "far writer", which was coined by French statesman André François Miot de Mélito. Today, in order to distinguish it from subsequent telegraph systems, the French name for Chappe's semaphore telegraph system is named after him, and thus is known as a "". Alternatively, Chappe coined the phrase "semaphore", from the Greek elements σῆμα (sêma, "sign"); and from φορός (phorós, "carrying"), or φορά (phorá, "a carrying") from φέρειν (phérein, "to bear").
