When he died, he was actually impoverished and in debt. It is stated in many sources that he died penniless and this is sad because he was actually very close to becoming the world's first billionaire.

Smiljan, Croatia. Born July 10, 1856.

We know that he was undoubtedly persecuted by the energy power brokers of his day - namely Thomas Edison, whom we are taught in school to revere as a genius. He was also attacked by J.P. Morgan and other "captains of industry." Upon Tesla's death on January 7th, 1943, the U.S. government moved into his lab and apartment confiscating all of his scientific research, some of which has been released by the FBI through the Freedom of Information Act. (I've embedded the first 250 pages below and have added a link to the .pdf of the final pages, 290 in total). Besides his persecution by corporate-government interests (which is practically a certification of authenticity), there is at least one solid indication of Nikola Tesla's integrity - he tore up a contract with Westinghouse that was worth billions in order to save the company from paying him his huge royalty payments.

Wireless electricity (high voltage) transmission can be done from a Tesla Coil transmitter and Tesla Coil receiver

If you have networking knowledge with good imagination, then This concept can be understood when relating it with wireless data communication between a sender and a receiver... It can also be related with satellite communication (where it can also be related with the communication with the Mars Rover)... Wireless communication as well as transistors was born from with reference to his patents/works...

He was a celibate and never married. As a matter of face, Tesla moved to New York because he could not develop his ideas. He was a Serbian American inventor, electrical engineer, mechanical engineer, physicist, and futurist best known for his contributions to the design of the modern alternating current(AC) electricity supply system. Tesla gained experience in telephony and electrical engineering before emigrating to the United States in 1884 to work for Thomas Edison in New York City. He soon struck out on his own with financial backers, setting up laboratories and companies to develop a range of electrical devices. His patented AC induction motor and transformer were licensed by George Westinghouse, who also hired Tesla for a short time as a consultant. His work in the formative years of electric power development was involved in a corporate alternating current/direct current "War of Currents" as well as various patent battles.

In my opinion yes; he invented direct current ,which was stolen by Edison, alternating current, remote control technology, radio waves, incandescent bulbs, wire less power ,which he never had the funding to complete, and many other inventions way out of there time in his lost journal, some rumored to be an earth quake machine. Another of his ideas was haarp a signal station that can bend the jet streams using radio frequencies to over heat the air and change and direct the climate. All Einstien did was relativity and the nuclear bomb while those are truly genius accomplishments compairing Tesla to Einstien would be like comparing Newton to DaVincii

Most historians think that he got the inventing from his mother, Duka, because she would invent tools. He was a celibate and never married.

He died in 7 January 1943 at age 86.

There was a mysterious fire in his lab and so Marconi claimed the prize. Later on Tesla received the credit and the patent for the radio since Marconi used 17 of Tesla's patents to build his system. All that was proved in court.
