Nikola Tesla
Nikola Tesla (10 July 1856 – 7 January 1943) was an inventor and a mechanical and electrical engineer. He was one of the most important contributors to the birth of commercial electricity and is best known for his many revolutionary developments in the field of electromagnetism in the late 19th and early 20th centuries. Tesla's patents and theoretical work formed the basis of modern alternating current (AC) electric power systems, including the polyphase system of electrical distribution and the AC motor, with which he helped usher in the Second Industrial Revolution.
In Assassins Creed canon, Tesla was an ally of the Assassins, who wanted him to destroy the Staff using his mastery of electricity. Unfortunately, this resulted to the Tunguska Explosion which either destroyed the Staff completely, or could have just blasted the Piece of Eden miles away.
