The fax machine was invented by a Scottish inventor Alexander Bain in 1843. He devised an apparatus comprising two pins that were connected to two pendulums through five wires. When an electric signal was sent from the transmitting end, the receiving end was able to reproduce the signal on an electrochemically sensitive paper impregnated with chemicals. Thirty-three years later, Alexander Graham Bell invented the telephone.
