BIOGRAPHICAL SUMMARY

At the stroke of midni.ght in the village of Smiljan, Lika, Nikola Tesla was born between July 9th and loth, 1856. During this time, Smiljan was under the jurisdiction of Austria-Hungary. It is now part of Yugoslavia. His father was the Reverend Milutin Tesla, a priest of the Serbian Orthodox faith. His mother's name was Djouka, and came from the household of Mandich. She was an inventor in her own right, creating many household devices. Early schooling was in Smiljan and Gospic, and upon reaching the age of fifteen, Nikola was sent to the Higher Real Gymnasium at Karlo- vac, Croatia. Until this time it was planned by his family that he become a minister. Tesla then experienced an extended illness, during which his father consented to the son's wishes to study in the field of mathematics and physics. At the age of nineteen, Tesla started his higher education at the Polytechnic School at Gratz, Austria. It was at Gratz that a demonstration of a Gramme dynamo exhibited the flaw of arcing brushes. The germ of the idea of a motor without a commutator was now created. Nikola was an outstanding student, and early in his schooling demonstrated the ability to work complex mathematical problems in his mind, arriving at an answer almost as soon as the problem was presented. This ability was to expand into even greater mental capabilities, almost beyond comprehension. In 1880, Nikola went to Prague, carrying out his father's wish to complete his education at the university. The next year he took a position as chief electrician of a newly formed telephone company in Budapest. Following another illness, he was employed by the Continen- tal Edison Company in Paris. It was during this period that the concept of an alternating current motor, based upon the rotating magnetic field principle, came to him in a flash of inspiration. Tesla next accepted an offer to work with Thomas A. Edison and, upon arriving in New York on June 6, 1884 (became naturalized citizen July 30, 1891), went to work designing direct current dynamos. Tesla quit immediately after failing to receive promised pay for design work. Backers for a new system of electric lighting were then secured, but at the end of a year he was richer by stock certificates of little value. By 1887, Tesla had obtained capital for a laboratory in which he produced working models of motors he had mentally devised. On May 16, 1888, he read a paper entitled "A New System of Alternate-Current Mot- ors and Transformers," before a meeting of the American Institute of Electrical Engineers in New York in which he announced his recently patented polyphase system of power transmission. Soon after, the patent rights were purchased by The Westinghouse Electric Company. en route to Colorado Springs to conduct experiments on wireless power transmission. There, he produced the greatest length point-to-point electrical discharges ever achieved by man, by means of an enormous Tesla coil called a Magnifying Transmitter, and startled the technical community with photographs and claims of his work. With the successful completion of his experimental work at Colorado Springs, Tesla returned to New York in January (1900) and the following year began construction of a world-wide communications system at Warden- clyffe, Long Island, sponsored in part by J. P. Morgan. However, the project was not completed because of insufficient funds, and the ulti- mate goal of wireless transmission of power to Paris was not demonstrated. During the next several years Tesla turned his attention to the development of a novel turbine which now bears his name. Summarizing his work of the preceding 12 years, Tesla gave an address entitled "New Inventions of Tesla" before a meeting of the National Electric Light Association in New York on May 15, 1911, in which he described his Magnifying Transmitter and turbine developments. It became evident to many in years following that Tesla had developed the fundamental concepts of television and radar, decades before their inception. He also spoke of the development of a "death ray". Many of his ideas, including the possibility of interplanetary communication, were simply too far ahead of the times. In the United States alone, 111 patents were issued to Tesla. It is estimated that his name can be linked to several hundred inventions. Many honors and awards were bestowed upon him, including honorary de- grees, the John Scott Medal, the Edison Medal, and awards from foreign countries. Mentally active but physically weak toward the end, Nikola Tesla died Jan. 7, 1943, in his rooms at the Hotel New Yorker, having perhaps contributed more to our present technical society than any other single individual. Later that year, the U. S. Supreme Court invalidated the fundamental radio patent of Marconi primarily on the basis of the prior work of Tesla. On the occasion of the Tesla Centennial Anniversary in 1956, the International Electrotechnical Commission announced that the unassigned unit of magnetic flux density in the MKS System be named "tesla" in his honor. In 1976, on the occasion of Tesla's 120th anniversary, the Institute of Electrical and Electronics Engineers (successor organization to the American Institute of Electrical Engineers) established the Tesla Award.
