"Morse telegraph stations, historical artwork. The station at top has two sets of telegraph wires connecting to the transmitting and receiving operating equipment on the desk. The station at bottom has twenty sets of telegraph wires connected to it; the switchboard at lower centre was used to switch between wires, and there are two sets of transmitting and receiving equipment either side, allowing several operators to work simultaneously. Telegraphy was pioneered by the US inventor Samuel Morse, who developed the Morse Code used to send messages as electrical signals over telegraph wires. Artwork from A Travers l'Electricite (G. Dary, Paris, 1900)." (KEYSTONE/SCIENCE PHOTO LIBRARY/SHEILA TERRY)
