Welcome to the Tesla Memorial Society of New York Website
Half a Century of the Nikola Tesla Museum in Belgrade
"During 2002-2005 the Nikola Tesla Museum marked fifty years since its foundation and the opening of its permanent display. It is a unique institution of science and culture, both in our country and in the world. It is entirely dedicated to the brilliant inventor, scientist and engineer Nikola Tesla. The unique quality of the Museum is in its memorial-historical yet scientific-technical orientation: it holds the entire legacy of Tesla, his personal archives, personal library and a multitude of personal objects, both memorial and technical."
-Marija Sesic, director, 2001-2005, Nikola Tesla Museum in Belgrade.

The remote control system, recognitions
In the last room of the Museum are shown Tesla's experiments and achivements in the field of remote control system. The reconstructed model of a small ship is exhibited, with which he laid the foundation of remote control system, when he, in New York in 1898, showed how the ships and mechanical gadgets in general could be controlled on a wireless principle.
The enlarged
photograph of the antenna of Tesla's "World's radiostation" which he
constructed in Long Island in the vicinity of New York, testifies his
farsightedness and ingenuity. His idea was that this station, build in
1900 should by remote wireless control transmit throughout the world not
only the news but music and photographs as well. However, that great plan
could not be carried out becouse Tesla did not have sufficient resources
to do so. That seems to be the direct cause for Tesla'a withdrawing from
people and leading an isolated life. Yet his great work remained as a
testimony of his creative life, as well as meny diplomas of recognition
given to him by many well-known world universities and scientific
institutions.
The greatest among all the recognitions, however, is the one given to
him posthumously (in 1960) by the International Commision for Electrical
Engineering, at its session in Philadelphia. That Commision decided that
the unit of magnetic induction is to be universaly called Unit "tesla" (as
well as formula)
So Tesla was included among the most outstanding scientists such as Volta, Ampere, Faraday, Kelvn and others.
The exhibition ends with the posthumous mask of Tesla, with the words of American inventor Armstrong next to it:
"The world will long have to wait for a mind
equal to Tesla's, a mind of such creative possibilities
and such wealth of magination."
Tesla's transformer and wireless transmission
Tesla's inventions in the field of currents of high frequency and high
voltage are exhibited in the next room. With his oscillator he was the
first to succeed in producing currents of high frequncy and of several
millions volts. This made the development of new technical fields
possible.
Sound of small oscillator-transformer discharge
It seems almost incredible today that Tesla managed to produce current
of more than tens of thousand periods frequency with several million volt
so many decades ago. Tesla experimented with such voltage in his
laboratory in New York as well as in
the laboratory in
Colorado Springs. Even today the result of these experiments are manifold
and represent a strong stimulus to the scholars throughout the world,
especially since the Museum of Nikola Tesla published Tesla's result, day
by day. Nowdays such oscillators and currents of high frequency are used
in radiotechnology, industry and in the process of releasing nuclear
energy, and Tesla himself forsaw their application in the fields of
medicine and industry. The high frequency oscilator with the big
transformer, placed in the middle of the room, of about 500.000 volts,
speaks of Tesla's genius and illustrates the producing of light without
wires. In this room there is also a smaller oscillator-transformer, Tesla
exsperimented with, using tubes with diluted gas.
These exsperiments
resulted in the present-day tehnology of luminescent light. Even experts
know little about Roentgen wondering at and admiring the photographs of
parts of human organism which were made with the help of Tesla's hight
frequency currents which were used to supply power the tubes producing
Roentgen rays.
The most significant experiments with current of high frequecy and high voltage, Tesla carried out in the field of wireless transmission. With the results attained he laid the foundation of the tehnique of wireless transmision, as testified by the exibited text of the judgement of the USA Supreme Court, by which Tesla's inventions in that field have a priority over Marconi's inventins.
The polyphase system and its application
In this room
various working models show how the idea of moving the rotating copper
plate by way of inductions currents odiginated (Arago's experiment from
1825). This room also contains the model of the motor with commuted direct
current and the immobile electromagnets (of the American physicist Bailey
from 1887) as well as Tesla's two-phase generator with the model of
synhronous and asynhronous motor moved by two-phase alternating currents.
For a fuller understanding of the physical principles of forming the
rotating magnetic field and for the visual presentation of the vectorial
addition of the two linearly oriented fields there is a model of the
hydaulic analogy, constructed according to Tesla's idea. In 1893, at the
Chicago World Exhibition, Tesla exhibited his ingenious model of the
induction motor in which the rotor was a freely rotating metal egg. Such a
model, together with the working model of the first "true" induction motor
with the rotor in short circuit, illustrates the most important part of
Tesla's polyphase system.

Tesla
participated with his patents in the contruction of the first big
generators for poluphase current, as testified by the plate from one of
the generators of the Niagara Plant (1889), placed by the model of
hydroenergetic system. The date of putting into operation the first
engines in this Plant is the actual beginning of the hydroenergetic system
with a three-phase alternating currents, exhibited in this room, show all
the essential elements of Tesla's invention.
This room also contains Tesla's invention of the turbine without blades (1913), of the pump and the rotor constructed on the same principle, which attract one's attention by their originality. Tesla devoted twenty years of his life to these inventions, trying to improve them and applay them in practice, and understanding, in the world of science.
Memory of the World, United Nations (Unesco)
2 September 2003 Some 600 works of the 10th century physician and scientist Ibn Sina and the archives of Nikola Tesla, a pioneer in electrification, are among the 23 documentary collections from 20 countries selected for inscription on the Memory of the World Register of library and archive material. The International Advisory Committee of UNESCO's Memory of the World Programme selected the collections during a meeting in Gdansk (Poland) that ended last Saturday.
Nikola Tesla's Archive in Belgrade (Serbia and Montenegro) constitutes a unique collection of 160,000 pages of patent documentation, scientific correspondence, scientific papers, manuscripts, technical drawings, scientific measuring data, personal documents and legal papers, as well as 1,000 original photographs of Tesla's experiments and inventions, all of which are indispensable to the study of the history of electrification.
A total of 91 properties from 45 countries are inscribed on the Memory of the World Register, which was established in 1997 to preserve and promote documentary heritage of universal value.
