The most famous mechanical engineer is probably Thomas Edison. He invented the electric light bulb, the phonograph, the movie camera, and the motion picture projector. He also invented the electric chair.
A very famous mechanical engineer is Nikola Tesla.
Tesla was born in 1856 in Smiljan, in the Kingdom of Croatia-Slavonia, then part of the Austrian Empire, and is buried in the Alley of the Millionaires at New York's Waldheim Cemetery.
He invented the induction motor, the Tesla coil, the alternating current system, and the polyphase system. He also invented the modern radio, the fluorescent lamp, and the Tesla coil.
The "Tesla coil" is an electromagnet with a primary coil (usually a solenoid) and a secondary coil. The primary coil is connected to a high-voltage, low-current source, such as a battery or a generator. The secondary coil is connected to a low-voltage, high-current load, such as an incandescent bulb or a loudspeaker.
He was also a pioneer in the development of the alternating current system of electric power transmission and distribution.
