Tesla parted company with Edison after being promised $50,000 for improving the design and efficiency of dynamos. Tesla insisted on the superiority of alternating current and its applications, whereas Edison believed it a dead end and championed direct current.

Tesla was a visionary who solved problems in a flash of insight, whereas Edison relied on patient trial-and-error in practical experiments.

Edison, who was impressed by his skill and hard work, but the two men were diametrically opposed in temperament and method. For nearly a year he worked for inventor Thomas A. In 1884 he immigrated to the United States, later becoming a naturalized citizen. There he constructed a telephone repeater and engaged in various branches of engineering and manufacture. He commenced his career as an inventor in Budapest, Hungary, in 1881. Afterward he enrolled in philosophy studies for two years at the University of Prague, Bohemia (now the capital of the Czech Republic). Tesla was a student for four years at the Polytechnic School, Gratz, Austria, studying mathematics, physics, and mechanics.

He was educated at an elementary school, then had four years at Lower Realschule, Gospic, Lika, which was followed by three years at the Higher Realschule, Carlstadt, Croatia. Even as a boy, he was inventive at the age of nine he constructed a 16-bug power motor by harnessing June bugs to a thin wooden wheel. He was born in July 10, 1856, in the village of Similjan in the Austro-Hungarian border area of Lika (now in Slovenia). After only a few years of consideration of the problem, the complete detailed vision of an alternating current motor using a rotating magnetic field came to him while he gazed at a sunset. For example, as a young student of electrical engineering and physics, at a time when the concept of alternating current was considered a fallacy of the perpetual motion type, he knew that he could solve this problem. The ideas flashed into his mind as working units, complete to the final details of component design and size. Unlike most innovators in the fields of engineering and electricity, his inventions did not require patient experiment and trial-and-error testing of models. Eccentric scientific genius whose inventions in the field of electrical apparatus stemmed from inspirations received in extraordinary visions of a paranormal character.
