 :::::Addressing ""Fountains:"" Tesla not accepting some theories which are not accepted does not make him ""not a scientist,"" anymore than it makes all the physicists who disagreed with general relativity ""not scientists."" Your opinion and original research do not trump mainstream present-day encyclopedias of scientific biography and modern biographies of Tesla which include ""Physicist"" as a descriptor. You claim ""writers say"" and then cite exactly one book, in contrast to the many I cited which called him a scientist or physicist. Binksternet is wrong when  he says Tesla did not leave detailed records. After his funds were gone and he was just a retired broke eccentric, talking about rayguns, then indeed he did not do scientific publication. But for earlier work he gave many well followed public demonstrations to scientific audiences which were written up in detail by himself and others, and he wrote volumes about his own work in radio, x-rays, his remote-control boat, wireless power to light lights, rotating magnetic fields, and induction motors, in the 19th century. His publications were numerous. If he were merely being evaluated for notability as a scientist, one might look at Google Scholar and similar citation sites to see if he published and if his papers were cited by others.He gave well-received lecture-dempnstrations to learned societies, for example. See ""High frequency oscillators for electro-therapeutic and other purposes,"" 1898, ""A new system of alternate current motors and transformers,"" 1888, ""Experiments with Alternate Currents of High Potential"" 1904, Experiments with alternate currents of very high frequency and their application to methods of artificial illumination 1891, Tesla, Nikola. ""On light and other high frequency phenomena."" Journal of the Franklin Institute 136.4 (1893): 259-279 (no free online view), ""The Inventions, Researches and Writings of Nikola Tesla: With Special ..."" published by TC Martin, 1894. This is not a complete listing, but it shows him as publishing his work in an exemplary way, and these publications have been cited by later workers. He was a highly regarded mainstream engineer and physicist in the 1890's.   "
