Samuel Morse was a man of vision. His vision, his dreams, have become the paving stones for what is now known as the information superhighway. The leading technology in the creation and progress of this telecommunication spectacle is the cell phone and its derivatives. So you may wonder how we got from Samuel Morse to where we are today…and where we’re going tomorrow. To ease your curiosity, following is a history of cell phones. Sit back, relax and enjoy. Samuel Morse invents the telegraph: Any history of cell phones starts with Samuel Morse. He conceived of an electromagnetic telegraph in 1832 and constructed an experimental version in 1835. Then, on October 18, 1842, Morse laid wires between Governor's Island and Castle Garden, New York, a distance of about a mile. Part of that circuit was under water because Morse wanted to show that an underwater cable could transmit signals as well as a copper wire suspended on poles. But before he could complete this demonstration a passing ship pulled up his cable, ending, it seemed, his experiment. However, undaunted, Morse proceeded without the cable, passing his telegraph signals through the water itself. This introduced the concept of wireless by conduction. Quite simply, Samuel Morse’s telegraph was the first device to send messages by electricity. And the ideas started pouring in
So now there was the know-how to send messages. And the possibilities of exactly how to do this were abounding. Now it was known that water could conduct electricity and carry messages, other conductors were sought out. In 1843, a skilled analytical chemist by the name of Michael Faraday began exhaustive research into whether space could indeed conduct electricity, using the principles already established by telegraphy. In 1864, James Clerk Maxwell released his paper "Dynamical Theory of the Electromagnetic Field" which concluded that light, electricity, and magnetism, were all related. All of these worked hand in hand, and all...
