There were some really marvelous early attempts at electric telegraphs to enhance the communication system. Here’s an electrostatic model, with a wire for each letter and number, and a range from the living room to the parlor, powered by some fur rolling over a piece of rubber — sort of the rub-a-balloon-on-yourhead approach.  16 Here’s another British multi-wire device with a battery and a saltwater receiver.  17 Remember how in high school chemistry lab if you put wires from a battery into saltwater, one of them bubbled? It was the same deal here. There was a ball for each letter, and you looked to see where the bubbles showed up. Here’s one that tried to use tones for letters. It was the first singing telegraph and made signals like the keyboard at the end of Close Encounters of the Third Kind.  18 I have no idea how this one was supposed to work, but when they said “sell,” you sold.  19 Julius Reuter and his son Herb  20 decided to try another approach. They got into the messenger pigeon business. Edward G. Robinson played Reuter in the 1941 classic film, This Man Reuter. The pigeons played themselves.  21 Finally, in 1837, Samuel Morse got it right: a nice, simple, single wire and ground design.  22 This quickly caught on all over the world. Instantaneous communication!  23 Notice here that “the electric fluid travels at the rate of 280,000 miles per second,” or about one and a half times the speed of light. Maybe they knew something we don’t. For the first time in history, a message could be sent instantly over the horizon. An entire book could be filled with the stories of how all facets of human endeavor were transformed by telegraphy.1 Traders picked up on telegraphy in a big way. Here we see a broker in New York with his 19th-century BlackBerry, a telegraph key, cradled in his arm.  24 In its day, telegraphy was seen as the same kind of overwhelming transformation that the Internet is today. It was a big advance, but to participate in the market as things were happening, the participant had to know Morse code. The technological revolution of the 1850s needed more technology to allow people to cope with the dramatic changes in the information landscape.
