History
Today
Nikola Tesla Museum is a unique institution of science and culture in Serbia and in the world. It is the only museum in the world which preserves the original and personal inheritance of Nikola Tesla. The director of the Museum is Vladimir Jelenkovi.
Exhibitions
The permanent exhibition was arranged in 1955. From time to time there were some modifications, but the basic concept remained the same. In its first part it is primarily a memorial exhibition, while in the second part it is an interactive one, with three-dimensional models of Tesla's inventions. From time to time the museum organizes thematic exhibitions of documents, photographs and other material, in order to display some periods from Tesla's inventive work or life.
esla's everyday life
The Nikola Tesla Museum has prepared an exhibition called esla's everyday life that contains a collection of textiles and various things used in everyday life in order to celebrate the 150th birthday of Nikola Tesla in Belgrade in 2006.
Reconstruction
The Nikola Tesla Museum is currently under reconstruction. The reconstruction on the building started November 3, 2006 and the first phase of the project will be complete by the end of 2006. The garden on the roof of the museum will be closed from the outside by glass windows, which will turn the roof into a computer room.
Sightseeing
The museum is divided into 7 separate rooms, with different themes, exponents, photographs and even the ashes of Nikola Tesla.
Room 1 - Nikola Tesla: a man and a creator
The life story of Nikola Tesla begins with the large-scale photograph from the period of studies in Graz (Austria). Three personal documents are placed under the photograph:
his birth certificate, his Abitur certificate from the secondary school at Karlovac, and the passport he travelled with to New York in 1894. There is also a photograph of the house which was his birthplace, and of the church where his father was the parish priest. This photograph illustrates his origin and the start of his life. A series of selected letters, placed on both sides of the photograph, witnesses the highest acknowledgements expressed to Tesla by the greatest scientists of his time: Einstein, Crookes, Kelvin, Rntgen, Millican, Popov, Pupin, Lee de Forest, Compton, Kennelly, Armstrong, etc.
Room 2 - Personal things and correspondence
Some small things from Tesla's personal effects are selected to depict his exceptional personality, way of living and relations with other people. In the show-cases are his hat, his travelling bag and small every-day items such as invitations, theatre entrance tickets, membership cards etc.
As the most valuable souvenir he kept the piece of needlework made by his mother, the embroidered bag typical for his native land Lika.
Selected documents and photographs from the abundant correspondence with his friends, writers and artists (George Westinghouse, Mark Twain, Robert U. Johnson, and others) are also in the show-case.
Records of Tesla's visit to Belgrade in 1892 in Belgrade newspapers of that time are also displayed, as well as the letters from Laza Kostic, a distinguished Serbian poet.
The photographs of Tesla's closest relatives - father Milutin, sisters Marica, Angelina and Milka, uncle Nikola and grand-grandfather Toma are displayed in a separate show-case.
The documents on his death and burial in New York in 1943 are exposed in the last show-case.
Room 3 - Urn with Tesla's ashes
In the third room of the Museum, in the gold-plated sphere on the marble pedestal is the urn with Tesla's ashes. After death Tesla was cremated and the urn was transferred to Belgrade in 1957.
Room 4 - "Fairy tale on electricity"
Tesla's fairy tale on electricity - an historical survey of man's achievement in exploring secrets of electricity; patents in the field of electro-energetic - Tesla's invention of poly-phase induction motor and a model of his system of production, transmission and distribution of electrical energy; patents in the field of high potential technic - oil transformers, and in the field of mechanical engineering - turbines
Room 5 - The polyphase system and its application
A series of interactive models illustrating the origin of the idea of the rotating magnetic field has also been exhibited: rotation of a copper plate by induced currents, the experiment of Arago from 1825, then the Baily motor with commutated direct currents and static electromagnets (1879) and Tesla two-phase generator together with the models of synchronous and asynchronous motor operated by two-phase alternate currents.
The hydraulic analogy, made according to an idea of Tesla, acquaints visitors with his conception of the physical principles of the rotating magnetic field visually demonstrating the vectorial addition of two identical sine curves, perpendicular to each other, with the phase difference of 90.
In 1893, at the World Exhibition in Chicago, Tesla had presented his witty model of the induction motor with egg-shaped rotor. This model, together with the working model of the first "genuine" induction motor with short-circuit rotor, depicts the most important part of the Tesla polyphase system.
The patents of Nikola Tesla laid the foundation for the construction of new generators of polyphase currents. It has also been witnessed by the plaque of one of the generators of the hydro-power plant at Niagara Falls (1899), placed next to the model of the hydro-energetic system. The date of bringing the first generators in this power plant into service marks the date of the beginning of electrification of the world. The small-scale model of the hydro-energetic system with three-phase currents placed in this room demonstrates all the essential elements of this invention of Nikola Tesla.
The story about Tesla's inventions is continued with the paddle-less turbine, pump and speed indicator constructed 1913 - 1916 on the same principle. Tesla had occupied himself more than twenty years trying to improve them, and it was not until the end of 20th century that these inventions began attracting attention and comprehension among scientists and engineers.
Room 6 - The Cordless Tesla Transformer
The exhibits depicting Tesla's inventions in the field of currents of high frequency and high potential are the most interesting ones in the Museum.
It seems today almost inconceivable that Tesla a century ago succeeded to produce alternating currents of several tens of thousands cycles per second and several million volts. With these currents he experimented in his laboratory in New York and later at Colorado Springs. The results of these experiments are even today inspiring for researchers in the whole world, especially after Nikola Tesla Museum has published his "Colorado Springs Notes".
In the contemporary world [such oscillators and] high-frequency currents are being applied in radio engineering, industry and medicine, in accordance with Tesla's farsighted anticipation.
The high-frequency oscillator coupled with a great transformer is placed in the middle of the room. It was built in 1955, in accordance with the technical descriptions from Colorado Springs. Its potential reaches roughly 200 000 volts and for half a century impresses visitors and fascinates children.
Beside the great oscillator there is also a smaller one, such as Tesla used in experiments with electrical discharges in tubes filled with rarefied gases. The results of these experiments laid foundations for the contemporary fluorescent illumination. These experiments are not sufficiently known even among specialists. Likewise it is also unknown that W. Roentgen was fascinated with X-ray images of human body he received from Tesla, obtained with X-ray tubes operated with high-frequency currents.
Tesla performed his most significant experiments with currents of high frequency and high potential in the field of wireless transmission of energy. The model of four resonant circuits displays the results which laid the foundations of wireless transmissions. Next to the model is the quotation from the verdict of the U.S. Supreme Court of 1943, granting the inventions of Nikola Tesla in this field precedence over those of G. Marconi.
Room 7 - Remote control and awards
The investigations and results of Nikola Tesla in the field of remote control are displayed with the reconstructed working model of a small boat. Such a boat he used in his experiments in 1898 in New York to demonstrate the possibilities of wireless control of moving of mechanical devices (vehicles, boats, etc.).
Anticipating with his inventions and experiments in this field, the development of remote control, Tesla was much ahead of his time. The large-scale photograph of his "World wireless station" at Long Island near New York depicts his intention to construct a transmitting station for particular purposes. According to his conception, that station built in 1900 was planned to transmit not only news but also music and photographs. However, this great plan remained unrealized.
Awards
Numerous decorations, honorary diplomas and awards exhibited in the last part of the exhibition symbolize the significance of his inventions. However, the greatest award was granted to him post-mortem by the International Commission for Electrical Engineering at its session in Philadelphia in 1960. The Commission decided to give the name "tesla" to the unit of magnetic induction. In this way Tesla became equally ranked with such outstanding scientists as Volta, Amper, Faraday, Kelvin, etc.
The death-mask of Nikola Tesla is the last exhibit, and next to it is the quotation of the American inventor E. Armstrong: "The World, I think, will wait a long time for Nikola Tesla's equal in achievement and imagination."

About the Author
I am an expert from China Quality Dress, usually analyzes all kind of industries situation, such as ceramic teapot , ceramic teapots.
Trying to cheat, are we?
Just kidding, but idk. I guess this wasn’t really much of an answer, was it? Use wikipedia, and then tell me the answer cause I’ll probably need to know too.
In what year did George Westinghouse buy patents from Nikola Tesla?
sci help
When did Nikola Tesla invent the radio and how did he do it?
ALso im pretty sure Marconi did not invent the radio marconi stole Teslas patents.
Why is Nikola Tesla under-recognized by the US education system?
Nikola Tesla’s inventions and contributions to science impact us every day of our lives, yet you don’t find him in today’s textbooks next to the names of other scientists/inventors. Why is he omitted from high school text books and not given the credit he diserved? I still hear references to Marconi having been the inventor of the radio, yet his patents were overturned in the 40′s and said to be based on Tesla’s work. So, why does our society still teach that Marconi invented the radio? Why isn’t Tesla a house hold name?
why do Americans think edison invented the light bulb…Nikola Tesla did?
Nikola Tesla sold the patent to Edison for a mill…why are our history books written backwards?
Tesla invented the alternating current induction generator, a device that changes mechanical energy into alternating current electricity, and the Tesla coil, a transformer that changes the frequency of alternating current.
Although many discoveries in the field of electricity were necessary to the development of radio, the history of radio really began in 1873, with the publication by the British physicist James Clerk Maxwell of his theory of electromagnetic waves.
Most everything electrical in use today was invented by Tesla. Not the light bulb, but most everything else. When he invented 3 phase motors, it was said that trying to build an electric motor without a commutator was impossible, a perpetual motion type of idea. Today they are commonplace.
This is a good example of the naysayers being proved wrong. When somebody says something is impossible, I like to think of Tesla. An example today would be the folks who say that it is impossible to develop thrust in space without ejecting mass.
Has it been done? No.
Is it possible? You tell me!
Your opinions on Nikola Tesla?
What is your opinion on NIkola Tesla? Do you think Edison really offered him $50,000? Do you think he should have given him the money? Was he really joking? What about the radio thing? Should he have gotten some credit because Marconi used 14 patents of Tesla’s? What is your overall opinion of the guy? I want answers from people who know about him and have read about him or at least know what they are talking about.
Tesla invented a type of arc lamp, not the incandescent light bulb. Regardless, Tesla was way, way cooler.
Tesla was a technical genius, but he was a dreadful businessman and (sadly) had no idea how to promote himself, so his genius was co-opted by folks like Westinghouse, Edison and even Ford. Because they got the public credit for much of his work, there are still public records repeating those mistakes.
Before he died, Tesla is alledged to have found a way to harness the earths magnetic field and the rotational movement of the earth to generate completely cost-free electricity, but the details probably died with him.
American society continues to adore “swashbuckling” heroes, which is why the schools STILL teach Columbus “discovered” America!
