- Italian inventor Guglielmo Marconi (pictured at right) first developed the idea of a radio, or wireless telegraph, in the 1890s. His ideas took shape in 1895 when he sent a wireless Morse Code message to a source more than a kilometer away.n 1919, Marconi’s resources were sold to General Electric and with that Radio Corporation of America (RCA, which spawned NBC Radio) - led by former Marconi employee David Sarnoff-was formed. The radio boom began, as people found it indispensable for receiving news and entertainment programs.

The History of the Electric Telegraph and Telegraphy However, it was Samuel Morse (1791-1872) that successfully exploited the electromagnet and bettered Joseph Henry's invention. Morse made sketches of a  magnetized magnet  based on Henry's work. Morse invented a telegraph system that was a practical and commercial success.amuel Morse. While a professor of arts and design at New York University in 1835, Samuel Morse proved that signals could be transmitted by wire. He used pulses of current to deflect an electromagnet, which moved a marker to produce written codes on a strip of paper-the invention of Morse Code.

- Daniel Webster, in the course of his plea, pointed to his client. The man whose cause he pleaded was a man of fifty-two, who looked fifteen years older, sallow and emaciated from disease. This was Charles Goodyear, inventor of the process which put rubber into the service of the world.n 1852, in Trenton, New Jersey, two men appeared in the Circuit Court of the United States, the legal giants of their day, to argue the case of Goodyear vs. Day for patent infringement. Rufus Choate represented the defendant (Day) and Daniel Webster the plaintiff (Goodyear).

Who Discovered Electricity But other than that, there was little real progress until the English scientist William Gilbert in 1600 described the electrification of many substances and coined the term electricity from the Greek word for amber. As a result, Gilbert is called the father of modern electric power. In 1660, Otto von Guericke invented a crude machine for producing static electricity. It was a ball of sulfur, rotated by a crank with one hand and rubbed with the other.

Alessandro Volta In brief he: • Invented the first electric battery – which people then called the “voltaic pile” – in 1800. Using his invention, scientists were able to produce steady flows of electric current for the first time, unleashing a wave of new discoveries and technologies. • Was the first person to isolate methane.

- In 1813, he constructed a 2,000-plate paired battery in the basement of Britain's Royal Society, covering 889 ft (83 m). Through this experiment, Davy deduced that electrolysis was the action in the voltaic pile that produced electricity. In 1820, the British researcher John Frederic Daniell improved the voltaic cell.

Who Discovered Electricity? Italian physicist Alessandro Volta discovered that particular chemical reactions could produce electricity, and in 1800 he constructed the voltaic pile (an early electric battery) that produced a steady electric current, and so he was the first person to create a steady flow of electrical charge.
