The history of the world describes the history of humanity as determined by the study of archaeological and written records. Ancient recorded history begins with the invention of writing. However, the roots of civilization reach back to the earliest introduction of primitive technology and culture.





After Wardencyiffe closed, Tesla continued to write to Morgan; after "the great man" died, Tesla wrote to his son Jack Morgan, trying to get further funding for the project. In 1906, he opened offices at 165 Broadway in Manhattan, trying to raise further funds by developing and marketing his patents. He went on to have offices at the Metropolitan Life Tower from 1910 to 1914; rented for a few months at the Woolworth Building, moving out because he could not afford the rent; and then to office space at 8 West 40th Street from 1915 to 1925. After moving to 8 West 40th Street, he was effectively bankrupt. Most of his patents had run out and he was having trouble with the new inventions he was trying to develop.

Other ideas, awards, and patents

Tesla theorized that the application of electricity to the brain enhanced intelligence. In 1912, he crafted "a plan to make dull students bright by saturating them unconsciously with electricity," wiring the walls of a schoolroom and, "saturating [the schoolroom] with infinitesimal electric waves vibrating at high frequency. The whole room will thus, Mr. Tesla claims, be converted into a health-giving and stimulating electromagnetic field or 'bath.'" The plan was, at least provisionally, approved by then superintendent of New York City schools, William H. Maxwell.

Before World War IWorld War IWorld War I, also known as the First World War, or the Great War, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70 million military personnel, including 60 million Europeans, were mobilized in one of the largest wars in history. The war drew in all the world's economic great powers, assembled in two opposing alliances: the Allies versus the Central Powers of Germany and Austria-Hungary. View World War I »World War I, Tesla sought overseas investors. After the war started, Tesla lost the funding he was receiving from his patents in European countries.

In 1917, Tesla received AIEE's highest honor, the Edison Medal.

In the August 1917 edition of the magazine Electrical Experimenter, Tesla postulated that electricity could be used to locate submarines via using the reflection of an "electric ray" of "tremendous frequency," with the signal being viewed on a fluorescent screen (a system that has been noted to have a superficial resemblance to modern radar). Tesla was incorrect in his assumption that high frequency radio waves would penetrate water. But Émile Girardeau, who helped develop France's first radar system in the 1930s, noted in 1953 that Tesla's general speculation that a very strong high-frequency signal would be needed was correct. Girardeau said, "(Tesla) was prophesying or dreaming, since he had at his disposal no means of carrying them out, but one must add that if he was dreaming, at least he was dreaming correctly."

In 1928, Tesla received his last patent, U.S. Patent 1,655,114, for a biplane capable of taking off vertically (VTOL aircraft) and then of being "gradually tilted through manipulation of the elevator devices" in flight until it was flying like a conventional plane. Tesla thought the plane would sell for less than $1,000, although the aircraft has been described as impractical.

At this time, Tesla closed his last office at 350 Madison Ave., which he had moved into two years earlier.

    HISTORIC PEOPLE

    Nikola Tesla (1856-1943)

    Nikola Tesla was a Serbian-American inventor, electrical engineer, mechanical engineer, physicist, and futurist who is best known for his contributions to the design of the modern alternating current (AC) electricity supply system. View Nikola Tesla (1856-1943) »

    Early Years: Tesla would later write that he became interested in demonstrations of electricity by his physics professor. Tesla noted that these demonstrations of this "mysterious phenomena" made him want "to know more of this wonderful force".

    Working at Edison: Edison manager Charles Batchelor, who had been overseeing the Paris installation, was brought back to the US to manage the Edison Machine Works, a manufacturing division situated in New York City, and asked that Tesla be brought to the US as well.

    Tesla Electric Light & Manufacturing: The investors showed little interest in Tesla's ideas for new types of alternating current motors and electrical transmission equipment.

    AC and the induction motor: In 1887, Tesla developed an induction motor that ran on alternating current, a power system format that was rapidly expanding in Europe and the United States because of its advantages in long-distance, high-voltage transmission.

    New York laboratories: Tesla and his hired staff would conduct some of his most significant work in these workshops.

    Wireless Power: At the time Tesla was formulating his ideas there was no feasible way to wirelessly transmit communication signals over long distances, let alone large amounts of power.

    Later Years: Before World War I, Tesla sought overseas investors. After the war started, Tesla lost the funding he was receiving from his patents in European countries.

    Death: On 12 January, two thousand people attended a state funeral for Tesla at the Cathedral of Saint John the Divine.

    Personal Life: For exercise, Tesla walked between 8 and 10 miles (13 and 16 km) per day. He curled his toes one hundred times for each foot every night, saying that it stimulated his brain cells.
