We urge you to turn off your ad blocker for The Telegraph website so that you can continue to access our quality content in the future. This made it possible to power electric devices in a more effective manner using relatively low voltages and high currents. Teleprinter machines came into use around 1925 and in 1936 Varioplex was introduced. He modified the Baudot Code by assigning code combinations with the fewest punched holes to the most frequently encountered letters and symbols.

Morse started by making sketches of a " magnetized magnet " based on Henry's work. He used pulses of current to deflect an electromagnet, which moved a marker to produce written codes on a strip of paper. Stearns of the United States completed refinement of the duplex transmission system originated in Germany by Wilhelm Gintl, which allowed the same line to be used simultaneously for sending and receiving, thus doubling its capacity.

However, many types of telegraphic communication have been employed since before recorded history. Advances in telegraph technology Soon after its introduction in Europe it became apparent that the American Morse Code was inadequate for the transmission of much non-English text because it lacked letters with diacritical marks. It is no longer a major means of commercial or maritime communications, but it is still used by amateur radio operators. Charles Wheatstone patented the Cooke and Wheatstone telegraph using the same principle of electromagnetism. As in the United States, development of the telegraph was carried out by highly competitive private companies, but a movement toward monopoly was strong.
