Marconi moved to Rome in 1935, never to leave Italy again. He died in the early hours of 20 July 1937 aged 63 and his body was laid to rest in the mausoleum in the grounds of Villa Griffone. In a fitting tribute3, wireless stations throughout the world fell silent for 2 minutes and the ether4 was as silent as it had been before Marconi. (10)

He left behind him a world that even before his death had come to regard radio as a commodity2, not a miracle. Britain even had an infant television service, broadcast via Marconi equipment. He also left behind a legion of detractors5 who correctly pointed out that others, such as Lodge and the Russian Alexander Popov, had sent wireless messages before Marconi got his patent. It does not really matter. What Marconi doubtless did invent was an entirely new science-based industry. We are used to being told that some new technology will change the world. Marconi's is one of the few that

did. (11)

The Genius Who Lit the World

Рис. 5 Nikola Tesla

Nikola Tesla was born on July 10, 1856 in Smiljan, Croatia, which was then part of the Austo-Hungarian Empire. His father was a Serbian Orthodox Priest and his mother was an inventor in her own right of household appliances. Tesla studied at the Realschule, the Polytechnic Institute in Graz, Austria and the University of Prague. At first, he intended to specialize in physics and mathematics, but soon he became fascinated with electricity. (1)

He began his career as an electrical engineer with a walking with a friend through the city park after seeing a telephone company in Budapest in 1881. Once when Tesla was demonstration of the "Gramme dynamo" (a machine that when operated in one direction is a generator, and when reversed is an electric motor), he visualized a rotating magnetic field. With a stick, he drew a diagram in the sand explaining to his friend the principle of the induction motor. Before going to America, Tesla joined Continental Edison Company in Paris where he designed dynamos. While in Strasbourg in 1883, he privately built a prototype of the induction motor and ran it successfully. Unable to interest anyone in Europe in promoting this radical device, Tesla accepted an offer to work for Thomas Edison in New York. His childhood dream was to come to America to harness the power of Niagara Falls. (2)

Nikola Tesla came to the United States in 1884 with an introduction letter from Charles Batchelor to Thomas Edison: “I know two great men,” wrote Batchelor, “one is you and the other is this young man.” Tesla spent the next 59 years of his productive life living in New York. Tesla set about improving Edison’s line of dynamos while working in Edison’s lab in New Jersey. It was here that his disagreement with Edison over direct current versus alternating current began and soon led to the war of the currents as Edison fought a losing battle to protect his investment in direct current equipment and facilities. Tesla pointed out the inefficiency of Edison’s direct current electrical powerhouses that have been built up and down the Atlantic seaboard. The secret, he felt, lay in the use of alternating current, because to him all energies were cyclic. Why not build generators that would send electrical energy along distribution lines first one way, than another, in multiple waves using the polyphase principle? (3)

Edison’s lamps were weak and inefficient when supplied by direct current. This

system had a severe disadvantage in that it could not be transported more than two miles due to its inability to step up to high voltage levels necessary for long distance transmission. Consequently, a direct current power station was required at two mile intervals. Direct current flows continuously in one direction; alternating current changes direction 50 or 60 times per second and can be stepped up to vary high voltage levels, minimizing power loss across great distances. He was convinced that the future belonged to alternating current. Nikola Tesla developed polyphase alternating current system of generators, motors and transformers and held 40 basic U.S. patents on the system. He introduced his motors and systems in a classic paper, “A New System of Alternating Current Motors and Transformers” which he delivered before the American Institute of Electrical Engineers in 1888. One of the most impressed was the industrialist and inventor George Westinghouse. One day he visited Tesla’s laboratory and was amazed at what he saw. Tesla had constructed a model polyphase system consisting of an alternating current dynamo, step-up and step-down transformers and A.C. motor at the other end. The perfect partnership between Tesla and Westinghouse for the nationwide use of electricity in America had begun. (4)

Later Tesla discovered the principle that drives almost every practical use of electricity today, the rotating magnetic field. The field is what powers generators and all forms of electrical motors. Although the generator had already been discovered, it was

Tesla who figured out why it worked. (5)

Tesla was a pioneer in many fields. The Tesla coil, which he invented in 1891, is widely used today in radio and television sets and other electronic equipment. That year also marked the date of Tesla's United States citizenship. His alternating current induction motor is considered one of the ten greatest discoveries of all time. Among his discoveries are the fluorescent light, laser beam, wireless communications, wireless transmission of electrical energy, remote control, robotics, Tesla’s turbines and vertical take off aircraft1. Tesla is the father of the radio and the modern electrical transmissions systems. He registered over 700 patents worldwide. His vision included exploration of solar energy and the power of the sea. He foresaw interplanetary communications and satellites. (6)

The Electrical Review in 1896 published X-rays of a man, made by Tesla, with X-ray tubes of his own design. They appeared at the same time as when Roentgen announced his discovery of X-rays. Tesla never attempted to proclaim priority. Roentgen congratulated Tesla on his sophisticated X-ray pictures, and Tesla even wrote Roentgen's name on one of his films. He published schematic diagrams describing all the basic elements of the radio transmitter which was later used by Marconi. In 1896 Tesla constructed an instrument to receive radio waves. He experimented with this device and transmitted radio waves from his laboratory on South 5th Avenue to the Gerlach Hotel at 27th Street in Manhattan. The device had a magnet which gave off intense magnetic fields up to 20,000 lines per centimeter. The radio device clearly establishes his priority in the discovery of radio. And in 1943 the United States Supreme Court, held Marconi's most important patent invalid, recognizing Tesla's more significant contribution as the inventor of radio technology. (7)
