An artist's projection of what the finished Tesla Tower would have looked like from the magazine "Electrical Experimenter", 1919. Tesla Tower (1901-17) was an early wireless transmission tower designed by Tesla in Shoreham, New York and intended for commercial trans-Atlantic wireless telephony, broadcasting, and proof-of-concept demonstrations of wireless power transmission. The tower was 187 feet high and the spherical top was 68 feet in diameter, but it was never completed nor fully operational. Nikola Tesla (July 10, 1856 - January 7, 1943) was a Serbian-American inventor, mechanical engineer, electrical engineer, and futurist. He was an important contributor to the use of commercial electricity, and is best known for developing the modern alternating current (AC) electrical supply system. He pioneered modern electrical engineering and many of his discoveries were of groundbreaking importance. He may have suffered from obsessive-compulsive disorder and was adamant about staying in a hotel room with a number divisible by three. Tesla died in1943 at age 86 from heart thrombus, alone in room 3327 of the New Yorker Hotel.
