Nikola Tesla

• Nikola Tesla (10 July 1856 – 7 January 1943) was a Serbian-American inventor, physicist, mechanical engineer, electrical engineer, and futurist.

• He was an important contributor to the use of commercial electricity, and is best known for his contributions to the modern alternating current (AC) electrical supply system.

Middle years

• In 1887, Tesla constructed a brushless alternating current induction motor, which he demonstrated to the American Institute of Electrical Engineers in 1888.

• In April 1887, Tesla began investigating what would later be called X-rays using his own single terminal vacuum tubes

Wireless energy transmission

• Tesla demonstrated wireless energy transmission as early as 1891. This so-called Tesla effect refers to the movement of energy through space and matter.

The war of currents

• In the late 1880s, Tesla and Thomas Edison became adversaries in part because of Edison's promotion of direct current (DC) for electric power distribution over the more efficient alternating current advocated by Tesla and Westinghouse.
