At this moment the country was in the throes of its first great Railway Mania, it saw the raising of huge sums of capital for companies to connect the major cities with each other by steam-powered railways.

The end of the French wars saw Government contract radically, its fiscal needs reduced and its need for loans, the commonest public investment, vanished; money was cheap. It was the advent of an era; where capital could be raised with ease and applied to great projects for public and private good, for gas and water utilities, banking, insurance, even cemeteries, as well as rails.

It was into this optimistic market that telegraphy entered. As their first business step W F Cooke and Charles Wheatstone established a formal partnership in a document dated November 19, to exploit their initial patent; such capital as was needed being raised on their own personal and limited security.

The master English patent of June 10, was followed by one for Scotland on December 12, and for Ireland during April A Mr Lancaster purchased a one-third share in the Irish patent. Cooke was to spend a similar sum on experimental instruments and materials by It is not useful to rehearse the tiresome arguments that immediately ensued between Cooke and Wheatstone regarding just about everything connected with the details of their many patents and their respective contributions; these have been effectively covered elsewhere.

But it is necessary to record the progress of their partnership from The Patentees At this time W F Cooke was styled a 'gentleman', that is a man without any formal occupation, in fact relying on limited family money.

Cooke had acquired a superficial knowledge of electricity attending lectures in German universities and had devised or adapted telegraphic apparatus. It can be fairly said that his contribution to the partnership was managerial and promotional; he controlled the business aspects and undertook all the negotiations, contracting in his own name to build lines of electric telegraph.

His commitment to establishing the telegraph, his energy and enthusiasm, if occasionally misguided, was undoubted. Cooke filed no more telegraphic patents after his partnership with Wheatstone ended.

In his later years he used the considerable capital he acquired from the telegraph in mining ventures and lost it all. In its original form it consisted of two large wooden frames, twenty yards apart each with nineteen horizontal wooden bars from which were suspended thirty-seven iron hooks.

Between the hooks was run a single length of eight miles of thin iron wire. This being before the awareness of the innovations of Volta or Galvani, the telegraph used static electricity, "lightning"!

A Leyden jar was kept charged by a frictional electric machine, this was to be the transmitter. A Canton pith-ball electrometer, two resin spheres suspended on silk threads, acted as the receiver. Once the Leyden jar was attached to the long iron wire the two pith-balls momentarily were attracted together as the electric power passed between them.

A little later Ronalds improved his telegraph by excavating a foot long four-foot deep trench in the garden and buried within it a two-inch square wooden trough lined with pitch containing another iron wire protected by thick glass tubes; this he connected to the Leyden Jar, the static electricity machine and the electrometer, successfully sending momentary electrical signals underground.

Unfortunately the discharge of frictional or static electricity is momentary; unlike the continuous current made by means of Voltaic cells or electro-magnetism.

Each discharge has to be generated individually. To communicate messages Ronalds had made two identical clock-like machines, each with a slow-moving index or hand, with the alphabet engraved around the dial.

In a man took his curious fifteen-year old nephew from London to view the telegraph in Mr Ronalds' garden. The boy's name was Charles Wheatstone. Charles Wheatstone was one of the outstanding academics of the 19th Century; devoted to developing theories and practical applications in many fields of physics.

It is worth noting that Wheatstone, apparently the shy academic, was also partner with his brother in a flourishing musical instrument business — he had invented, patented and continued to develop the concertina between and In the s and s he investigated an acoustic communication process that he called the telephone.

Always fascinated by language he used the word microphone, before such a thing was perfected.

With his patent of Wheatstone introduced several forms of electro-motor, or electro-magnetic engine, converting electricity into rotary motive power, as well as the first linear electric motor, controlling their speed with a rheostat of his own devising.

He invented a magnetic clock, and the stereoscope for viewing stereoscopic images, as well as making manifold improvements and innovations in electric telegraphy over forty years, including the first electric type-printing telegraph in and the automatic telegraph to carry bulk traffic in Wheatstone was the first to give credence to underwater telegraphy in In the same year he devised an electric daisy-wheel printer for the telegraph which he perfected in ; and the chronoscope for measuring small intervals of time.

In he produced the thermometer-telegraph for measuring temperature in the upper atmosphere using a balloon or within the depths of the earth in bore-holes. The commercial value of these innovations seems to have escaped him.Slavery in the United States was the legal institution of human chattel enslavement, primarily of Africans and African Americans, that existed in the United States of America in the 18th and 19th centuries.
