Menlo Park, New Jersey is where Thomas Alva Edison (1847-1931), America’s greatest inventor, developed technology that changed the world. Nicknamed the “Wizard of Menlo Park”, Edison resided and worked at Menlo Park from 1876 to 1884, turning the site into a center of invention and innovation.  


== Significant dates  ==
The [[Thomas Edison at Menlo Park|Menlo Park laboratory]] was the first center for research in which investigation by a team of individuals with diverse technical backgrounds and experience would be focused on developing practical products. This New Jersey site was chosen by Edison to escape from the hectic New York metropolitan area so that he could focus solely on the invention process. The lab was equipped with the latest state-of–the-art scientific electrical, chemical and mechanical instruments, tools and materials required to perform experiments.


<p>1828 – Shilling made the first experiments. By means of the electric current transferred along the wires stretched between two locations, the telegraph writes signs, which make an alphabet, words, speeches, and so on. </p>
In 1877, Edison successfully developed the carbon button transmitter (or [[Microphone|microphone]]) and the induction coil that greatly improved on the Bell telephone. These Edison innovations enabled the telephone to be used simultaneously as both a sound transmitter and receiver and allowed communication over longer distances with greater clarity and volume.  


<p>The end of 1820 to the beginning 1830 – Shilling`s demonstrations (including for&nbsp;the Tsar) in St.Petersburg. </p>
In the same year, Menlo Park became the “Birthplace of Recorded Sound” with the invention of the [[Phonograph|phonograph]]. Edison successfully recorded the movements of a diaphragm generated by sound on a piece of paraffin paper with a needle and then played back the sound by passing the paper back through the diaphragm again. A more complex cylindrical device using tin foil as the recording media followed. This invention, his favorite, was a logical extension of his previous work with the telegraph and the telephone.  


<p>1835 - Shilling`s demonstrations in Bonn at the congress of scientists and doctors. </p>
On New Year’s Eve 1879, the first use of practical incandescent lights for street lighting was demonstrated at Menlo Park right on Christie Street. This event foreshadowed the end of the gas light era and the beginning of the electric light and power industry. Soon after, Edison began to test his future lighting system with an electric network of feeder, mains and service wires. Wooden lampposts were installed along imaginary streets and half dozen houses were wired along with the laboratory and other buildings. The system was successfully demonstrated in 1881 and led to the award of a franchise to electrify New York City in that year.  


<p>1836 – The offer on sale of Shilling’s invention to the English Government. Test made by Russian Governmental commission of Shilling's telegraph in the Admiralty (St.-Petersburg). Two outermost buildings of Admiralty were connected by means of a cable line with the length of 5 kilometers in 1836. This line passed along the neighboring streets and partially under water (on the bottom of the canal). </p>
Edison also pioneered in railroad electrification. In 1880, a prototype electric railway was constructed at Menlo Park running about one-third of a mile around a hill and back. A small electric locomotive was powered by a [[Dynamo|dynamo]] functioning as a motor. Current was supplied from the generating station in back of the laboratory to the rail.  


<p>1837 - In May 1837 a decision to construct a telegraph between Peterhof and Kronstadt followed, but due to Shilling’s death in July 1837 it was not actually built. </p>
The years at the Menlo Park labs were most productive in Edison’s working life. From 1876 through 1884, over 400 patents for electrical, electro-technology or electro-mechanical devices were generated at Menlo Park. To commemorate Edison, the Thomas Alva Edison Memorial Tower and Menlo Park Museum was built in 1937 and dedicated to him the following year. The Tower is located where Thomas Edison had his laboratory.  


<p>P.L. Shilling summarized the experience of many physicists and started a new page in the history of Science and Technology. Shilling's telegraph device&nbsp;had a visual indication of the signals transferred on electric wires. The signals were easily decoded and turned into letters by the operator of the receiving telegraph apparatus , according to the special table of codes developed by P.Shilling. This telegraph, based on visual reception of codes, became a pattern for many of the following electromagnetic telegraphs, such as needle, recording and type-printing ones. </p>
The Menlo Park site was totally devoted to the advancement of the application of science and technology for practical products to be used for the benefit of society. The inventions and innovative achievements produced at Menlo Park impacted all aspects of the world. At the site, Thomas Edison carried out technology innovation, business creation and societal improvements which continue on today. In addition, Menlo Park became an important model for the industrial research laboratories of the early 1900s. Every major corporation and university has a research and development laboratory, recorded sound is everywhere, telephone and electric light and power systems blanket the globe. It all began at Menlo Park where “Today was Invented.


<p>P.L.Shilling’s invention of the electromagnetic telegraph was an important event in the development of science and gave an impetus to the scientific and technical thinking of many inventors.

<p>Shilling’s electromagnetic telegraph was not turned into commercial opportunity, but it became a model for designing many telegraphs and thus indirectly affected the development of telegraph communication all over the world. New ways of exchanging information were opened. </p>
 
<p>Shilling’s invention of electromagnetic telegraph had been prepared by all previous development of physics ([[Hans Christian Oersted|H.C. Oersted]], [[Andre-Marie Ampere|A.-M.Ampere]]). Invention of the first electromagnetic indicator of an electric current ("multiplier") in 1820 by I. Schweigger and of an electromagnet in 1825 by W. Sturgeon meant that more sound background for creation of electromagnetic telegraph appeared. P.Shilling was the first to create such electromagnetic telegraph. P.Shilling didn’t patent the development, but scientists in the Europe and America knew about his invention. </p>

<p>An essential change was introduced into Ampere’s idea: Shilling encoded the information and reduced quantity of wires up to six. P.Shilling’s telegraph apparatus (demonstration took place in 1932) consisted of six electromagnetic indicators, each of them operated by a separate pair of wires (6 signal, one call and one general - 8 wires totally). Depending on the direction of the current in this or that pair of wires, the black circle or the white circle of the disk indicator faced the operator. Such design allowed to induce a combination for coding any of two to the sixth power of code units, that is 64 signs, that was enough for encoding all letters, figures and special signs. </p>

This mistake is a result of the following circumstances. P.Shilling demonstrated his device in 1835 in Bonn at the congress of a German society of scientists and doctors. George Munke, the chairman of the congress, the professor of Heidelberg university and the honorary member of the St. Petersburg Academy of Sciences praised the work of a Russian scientist in the field of telegraphy and later demonstrated the model of an electromagnetic telegraph during his lectures. </p>

It had achieved remarkable results. </p>
