Nikola Tesla worked for Thomas Edison for about a year in the 1880s before leaving due to disagreements over payment and differing opinions on electrical technology.
Tesla demonstrated "the transmission of electrical energy without wires" as early as 1891. When Tesla was 41 years old, he filed the first basic radio patent (No. US645576). The year was 1897.
Tesla then studied electrical engineering at the Austrian Polytechnic in Graz (1875). While there, he studied the uses of alternating current. Some sources say he received Baccalaureate degrees from the university at Graz. However, the university claims that he did not receive a degree and did not continue beyond the first semester of his third year, during which he stopped attending lectures.
