10 July 1856 – 7 January 1943 (aged 86)

Nikola Tesla (/ˈtɛslə/Serbian Cyrillic: Никола Тесла; pronounced [nǐkola têsla];10 July 1856 – 7 January 1943) was a Serbian-American inventorelectrical engineermechanical engineer, and futurist best known for his contributions to the design of the modern alternating current (AC) electricity supply system.

Born and raised in the Austrian Empire, Tesla studied engineering and physics in the 1870s without receiving a degree, gaining practical experience in the early 1880s working in telephony and at Continental Edison in the new electric power industry. In 1884 he emigrated to the United States, where he became a naturalized citizen. He worked for a short time at the Edison Machine Works in New York City before he struck out on his own. With the help of partners to finance and market his ideas, Tesla set up laboratories and companies in New York to develop a range of electrical and mechanical devices. His alternating current (AC) induction motor and related polyphase AC patents, licensed by Westinghouse Electric in 1888, earned him a considerable amount of money and became the cornerstone of the polyphase system which that company eventually marketed.

Attempting to develop inventions he could patent and market, Tesla conducted a range of experiments with mechanical oscillators/generators, electrical discharge tubes, and early X-ray imaging. He also built a wireless-controlled boat, one of the first-ever exhibited. Tesla became well known as an inventor and demonstrated his achievements to celebrities and wealthy patrons at his lab, and was noted for his showmanship at public lectures.

Throughout the 1890s, Tesla pursued his ideas for wireless lighting and worldwide wireless electric power distribution in his high-voltage, high-frequency power experiments in New York and Colorado Springs.

In 1893, he made pronouncements on the possibility of wireless communication with his devices. Tesla tried to put these ideas to practical use in his unfinished Wardenclyffe Tower project, an intercontinental wireless communication and power transmitter but ran out of funding before he could complete it.

After Wardenclyffe, Tesla experimented with a series of inventions in the 1910s and 1920s with varying degrees of success. Having spent most of his money, Tesla lived in a series of New York hotels, leaving behind unpaid bills. He died in New York City in January 1943.

Tesla’s work fell into relative obscurity following his death, until 1960, when the General Conference on Weights and Measures named the SI unit of magnetic flux density the tesla in his honor.

There has been a resurgence in popular interest in Tesla since the 1990s.

Death ray

The death ray or death beam was a theoretical particle beam or electromagnetic weapon first theorized around the 1920s and 1930s. Around that time, notable inventors such as Guglielmo Marconi, Nikola TeslaHarry Grindell MatthewsEdwin R. ScottErich Graichen and others claimed to have invented it independently.

 In 1957, the National Inventors Council was still issuing lists of needed military inventions that included a death ray.

While based in fiction, research into energy-based weapons inspired by past speculation has contributed to real-life weapons in use by modern militaries sometimes called a sort of “death ray”, such as the United States Navy and its Laser Weapon System (LaWS) deployed in mid-2014.

 Such armaments are technically known as directed-energy weapons.

Tesla: Man Out of Time

Tesla: Man Out of Time (ISBN0139068597) is a 1981 biography of Nikola Tesla by Margaret Cheney. The book describes the life of Nikola Tesla (1856–1943), the Serbian-Americaninventor. Margaret Cheney’s narrative details Tesla’s childhood during the 1850s and 1860s in the then Austro-Hungarian Empire, his 1884 arrival in New York, becoming an American citizen in 1891, his inventions and contributions to engineering, up to his death New York at age 86 during the middle of World War II in 1943. The book is focused largely on Tesla’s personality and not his inventions.
