Its origins can be traced back long before 1837, when the first `practical' telegraph was patented in England by William Fother- gill Cooke and Professor Charles Wheatstone, but the stimulus necessary for its development was not provided until the expan- sion of the railway network in Britain and the United States in the 183os; the electric telegraph and the railways were to ex- pand together. The need for some means of communication faster, not merely than the horse but than the train itself, became clear. During the eighteenth century many telegraphs were proposed using electricity. Although not wholly understood, attempts were made to utilise the remarkable qualities of this mysterious form of energy. The discovery in 1745 of the Leyden jar gave a great impetus to experimentation. In April 1746 Abbe Nollet transmitted the shock of a jar through a number of Carthusian monks joined together by iron wires in a circle 5,400ft in circum- ference. The contortions of the monks, when the circuit was closed, were accepted as sufficient evidence of the shock having been felt throughout the whole circuit. That these contortions took place simultaneously showed that the time occupied by electricity in traversing the circuit was too small to be per- ceptible.1 Appreciating that electricity would travel almost in- stantaneously along a wire from one point to another, no matter how widely separated, several men attempted to use it for the transmission of information. In 1747 Sir William Watson, a member of the Royal Society, passed electricity through 9,000ft of earth and water on the Thames and through 1o,000ft of wire suspended at Shooters Hill. In 1748 Franklin repeated similar experiments in Philadelphia. In 1749 Du Lac experimented across Lake Geneva.2 However, the frictional or static electricity em- 13 14 ORIGINS AND DEVELOPMENTS TO 1837 ployed in all these early experiments was both fitful and difficult to insulate. Some of these early systems used an alphabetical basis in- dicating every letter by a separate movement or light at the receiver. Such a suggestion was made in an anonymous letter signed `C.M.' published in the Scots Magazine in February 1753.3 This 'expeditious method of conveying intelligence' was based on a separate wire for each letter of the alphabet and was 'otherwise somewhat intricate in its operations'. The author's reason for concealing his identity may have been his fear of being regarded as a magician by his neighbours. However, it seems probable that `C.M.' was Charles Marshall of Paisley, 'a clever man . who could make lightning speak and write upon the wall'.4 Other meth- ods used codes which employed combinations of single signals to distinguish letters. The first method was clear to the uninitiated; the second was more economical in wires and equipment. Between 175o and i800 developments occurred which were to be decisive. As a result of the work of the Italian physicists, Luigi Galvani and Alessandro Volta, the battery was invented, supply- ing a gentle, steady and controllable flow of current at modest voltage. Its power was both in the strength of the current and its ability to flow continuously. This enabled certain of the effects of electricity to be clearly observed and applied to practical ends for the first time. Volta, professor of natural philosophy at Padua, communicated his discoveries to the Royal Society in i800. He showed that the source of the electricity in Galvani's experiments was contact between two different metals. Within a matter of months, large electric batteries were being built on Volta's prin- ciple. In Munich S. T. Von Soemmering used an electrolytic battery to send signals which were indicated at the receiving end by the liberation of bubbles of hydrogen from the liquid in which the electrical impulse was discharged. In July 1809 he exhibited a telegraph through z,000ft of cable. The discovery that an electric current flowing through a coil could cause a movement in a magnet suspended nearby, was a great step forward in the understanding of electromagnetism. In Denmark, at the University of Copenhagen, Hans Oersted, experimenting with the current from a battery, discovered a de- ORIGINS AND DEVELOPMENTS TO 1837 1 5 finite relationship between electricity and magnetism. In France, at the Polytechnic School in Paris, Andre Ampere, mathematician and physicist, heard in September 1810 of Oersted's discovery of a magnetic needle being deflected by a voltaic current. He de- veloped the subject, published papers, and showed that magnetic deflection could be produced without magnets by the aid of electricity alone. Meanwhile in Barcelona, out of the mainstream of European science, Francisco Salva employed a multiple-wire scheme.
