Samuel F.B. Morse's first demonstration model of his telegraph was made with wooden canvas stretchers in 1837. The transmitter is in the lower foreground and would evolve into the telegraphic key. The larger structure is the receiver, with an electromagnet, that operated a pen on a moving strip of paper.
