Nikola Tesla´s achievements in the electrical art

“In the interval since Tesla did his really great creative work his name has been associated with so many projects of questionable scientific quality that I imagine they may have raised doubts in the minds of many as to his real achievements” (Doctor Frank B. Jewett in a letter dated January 1943). The Edison Medal (1916) was awarded by the AIEE to Tesla “for his early original work in polyphase and high frequency alternating currents.”¹⁸ To record his “real achievements,” the accompanying two articles have been prepared by authors selected for their qualifying experience and professional standing.
