telegraph invention


He even decided at first to become an artist rather than an inventor. Experiments continued at the Vail shops, with all the partners working day and night.

The receiver, or register, embossed the dots and dashes on an unwinding strip of paper that passed under a stylus. One of the men replied that electricity passes instantly over any known length of wire and referred to Franklin's experiments with several miles of wire, in which no appreciable time elapsed between a touch at one end and a spark at the other. The first crude telegraph system was made without electricity. This made it possible to power electric devices in a more effective manner using relatively low voltages and high currents. He did receive a French patent.
Before the development of the electric telegraph, visual systems were used to convey messages over distances by means of variable displays.

At the height of its use, telegraph technology involved a worldwide system of wires with stations and operators and messengers, that carried messages and news by electricity faster than any other invention before it. President Lincoln's first inaugural speech was carried to California by the Pony Express. The young American republic wanted just such a system along its entire Atlantic coast and offered a prize of $30,000 for a workable proposal. Despite what he had learned at Yale, Morse found when he began to develop his idea that he had little real understanding of the nature of electricity, and after sporadic attempts to work with batteries, magnets, and wires, he finally turned for help to a colleague at the University of the City of New York, Leonard D. Gale.
This system rapidly caught on in England and in the United States, where a number of sites bearing the name Telegraph Hill or Signal Hill can still be found, particularly in coastal regions. At midnight the session would close. She then informed him that her father was present until the close, and, in the last moments of the session, the bill was passed without debate or revision.

In 1820 Hans Christian Ørsted of Denmark discovered that a magnetic needle could be deflected by a wire carrying an electric current. This was particularly highly developed in Africa. As he ate breakfast the next morning, a young lady with a smile, exclaimed, "I have come to congratulate you!"

Assured by his friends that there was no possibility of the bill being reached, he left the Capitol and retired to his room at the hotel, broken-hearted. The type could be moved through a mechanism in such a manner that the dots and dashes would make and break the contact between the battery and the wire to the receiver. In 1844, the first commercial telegraph line was open for business.

Morse assured her it was not possible, as he remained in the Senate-Chamber until nearly midnight. The idea of using electricity to communicate over distance is said to have occurred to Morse during a conversation aboard ship when he was returning from Europe in 1832.

Too much time had been wasted laying bad wire, and with the project on a rigid deadline, something had to be done quickly.

This system allowed for communication to occur without t… The first two practical electric telegraphs appeared at almost the same time. The framers of this legislation had no way of knowing that when they used the word "telegraph" to refer to this visual semaphore system, they would be offered an entirely new and revolutionary means of communication--electricity.

In that year [1836] Samuel Morse took into his confidence one of his colleagues in the University, Leonard Gale, who assisted Morse in improving the telegraph apparatus. Samuel (or Finley, as he was called by his family) attended Yale at the age of fourteen and was taught by Benjamin Silliman, Professor of Chemistry, and Jeremiah Day, Professor of Natural Philosophy, later President of Yale College, whose teaching gave Samuel the education which in later years led to the invention of the telegraph. Samuel Morse was a gifted artist; in fact, he earned a part of his college expenses painting miniatures at five dollars apiece.

However, many types of telegraphic communication have been employed since before recorded history. The electric telegraph did not burst suddenly upon the scene but rather resulted from a scientific evolution that had been taking place since the 18th century in the field of electricity. The only transportation to California was by stage-coach, a sixty-day journey. In 1837 the British inventors Sir William Fothergill Cooke and Sir Charles Wheatstone obtained a patent on a telegraph system that employed six wires and actuated five needle pointers attached to five galvanoscopes at the receiver. Soon, as overhead wires connected cities up and down the Atlantic coast, the dots-and-dashes method that recorded messages on a long moving strip of paper was replaced by the operator's ability to interpret the code in real time (once the receiver was given two different types of "stop" pin that each made a different sound) and transcribe it into English letters as he heard it. In 1829, he returned to Europe to study art for three years. The word "telegraph" is derived from Greek and means "to write far," which describes exactly what a telegraph does.

Application of the battery to telegraphy was made possible by several further developments in the new science of electromagnetism. In 1837 he was granted a patent on an electromagnetic telegraph. Telegra.ph is a minimalist publishing tool that allows you to create richly formatted posts and push them to the Web in just a click. The towers were spaced at intervals of 5 to 10 km (3 to 6 miles), and a signaling rate of three symbols per minute could be achieved. To establish quicker communication with California, the Pony Express mail route was organized. Mary Bellis covered inventions and inventors for ThoughtCo for 18 years. Gale was a professor of chemistry and familiar with the electrical work of Princeton's Joseph Henry, a true pioneer in the new field. Ezra Cornell built more telegraph lines across the United States, connecting city with city, and Samuel Morse and Alfred Vail improved the hardware and perfected the code. Employing the semaphore system invented by French engineer Claude Chappe in 1791, towers spaced 5 to 10 km (3 to 6 miles) apart could relay messages cross-country in minutes.

One interesting result of Samuel Morse's 1838 trip to Europe was something not related to the telegraph at all.

Morse had formed a partnership with Alfred Vail, who was a clever mechanic and is credited with many contributions to the Morse system. Previous methods of producing electricity employed frictional generation of static electricity, which led to high voltages and low currents. However, Samuel Morse was still devoted to his art, he had himself and three children to support, and painting was his only source of income. Most were visual or "semaphore" systems using flags or lights. In February 1838, Samuel Morse set out for Washington with his apparatus, stopping at Philadelphia on the invitation of the Franklin Institute to give a demonstration. By 1859, both the railroad and the telegraph had reached the town of St. Joseph, Missouri. Rather, the drum beats followed the tonesof the language. It was a system of semaphores or tall poles with movable arms, and other signaling apparatus, set within physical sight of one another. The telegraph messaged the offer to Wright, who telegraphed back to the Convention his refusal to run. Dana visited Morse's studio often, where the two men would talk for hours. Long before Samuel F. B. Morse electrically transmitted his famous message "What hath God wrought?" "Mr. Day's lectures are very interesting," the young student wrote home in 1809; "they are upon electricity; he has given us some very fine experiments, the whole class taking hold of hands form the circuit of communication and we all receive the shock apparently at the same moment.". Allston was then living in Boston but was planning to return to England, he arranged for Morse to accompany him as his pupil.
