Throughout the 19th century, Philadelphia's Franklin Institute was often the organizer of American-held international exhibitions that showcased the achievements of industrial civilization. For example, it played a key role in organizing and hosting the International Electrical Exhibition of 1884 in Philadelphia. This, the first great electrical exposition in the United States, was held from September 2 to October 11, 1884. [1]
The show featured the displays of 196 commercial exhibitors and 1,500 exhibits, including a historical exhibit that featured devices used by Benjamin Franklin and the first Morse telegraph instrument. The novel application of electricity to the running of a railroad train, printing presses, sewing machines was demonstrated, as was an electrical searchlight, which had never been seen before.
Many of Thomas Edison's companies had display booths at the exhibition. The Edison Electric Light Company showed in operation their system of house lighting as supplied from a central station. The Edison Company for Isolated Lighting exhibited their system of lighting factories, hotels, hospitals, and other places situated beyond the reach of a central lighting station. A full assortment of Edison light bulbs (including experimental ones demonstrating the Edison effect) and dynamos also made up parts of other exhibits, as well as a quarter-length bust of Edison made of bronzed plaster by Rupert Schmid.
More than 285,000 people attended the International Electrical Exhibition of 1884, which was held in a large building built for this purpose at 32nd Street and Lancaster Avenue. The landmark exposition resulted in the formation of the American Institute of Electrical Engineers, an ancestor of today's Institute of Electrical and Electronics Engineers.
During the International Electrical Exhibition, the National Conference of Electricians was convened on September 8–13, 1884, at the Franklin Institute. This was the first national convention of electricians in the nation. The summit was authorized and organized by the United States Electrical Commission, which President Chester A. Arthur had formed earlier that year under an act of Congress. It was funded to the amount of $7,500 by the federal government. [2]
Nikola Tesla was a Serbian-American inventor, electrical engineer, mechanical engineer, and futurist. He is known for his contributions to the design of the modern alternating current (AC) electricity supply system.
Thomas Alva Edison was an American inventor and businessman. He developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures. These inventions, which include the phonograph, the motion picture camera, and early versions of the electric light bulb, have had a widespread impact on the modern industrialized world. He was one of the first inventors to apply the principles of organized science and teamwork to the process of invention, working with many researchers and employees. He established the first industrial research laboratory.
The World's Columbian Exposition, also known as the Chicago World's Fair, was a world's fair held in Chicago from May 5 to October 31, 1893, to celebrate the 400th anniversary of Christopher Columbus's arrival in the New World in 1492. The centerpiece of the Fair, held in Jackson Park, was a large water pool representing the voyage that Columbus took to the New World. Chicago won the right to host the fair over several competing cities, including New York City, Washington, D.C., and St. Louis. The exposition was an influential social and cultural event and had a profound effect on American architecture, the arts, American industrial optimism, and Chicago's image.
The Centennial International Exhibition, officially the International Exhibition of Arts, Manufactures, and Products of the Soil and Mine, was held in Philadelphia from May 10 to November 10, 1876. It was the first official world's fair to be held in the United States, and coincided with the centennial anniversary of the Declaration of Independence's adoption in Philadelphia on July 4, 1776.
The Franklin Institute is a science museum and the center of science education and research in Philadelphia, Pennsylvania. It is named after the American scientist and statesman Benjamin Franklin. It houses the Benjamin Franklin National Memorial. Founded in 1824, the Franklin Institute is one of the oldest centers of science education and development in the United States. Its chief astronomer is Derrick Pitts.
The National Electric Light Association (NELA) was a national United States trade association that included the operators of electric central power generation stations, electrical supply companies, electrical engineers, scientists, educational institutions and interested individuals. Founded in 1885 by George S. Bowen, Franklin S. Terry and Charles A. Brown, it represented the interests of private companies involved in the fledgling electric power industry that included companies like General Electric, Westinghouse and most of the country's electric companies. The NELA played a dominant role in promoting the interests and expansion of the U.S. commercial electric industry. The association's conventions became a major clearinghouse for technical papers covering the entire field of electricity and its development, with a special focus on the components needed for centralized power stations or power plants. In 1895 the association sponsored a conference that led to the issue of the first edition of the U.S. National Electrical Code. Its rapid growth mirrored the development of electricity in the U.S. that included regional and statewide affiliations across the country and Canada. It was the forerunner of the Edison Electric Institute. Its highly aggressive battle against municipal ownership of electric production led to extensive federal hearings between 1928 and 1935 that led to its demise. Its logo is an early depiction of Ohm's law which is "C equals E divided by R," or "the current strength in any circuit is equal to the electromotive force divided by the resistance," or the basic law of electricity. It was established in 1827 by Dr. G. S. Ohm.
Pavel Nikolayevich Yablochkov was a Russian electrical engineer, businessman and the inventor of the Yablochkov candle and the transformer.
Frank Julian Sprague was an American inventor who contributed to the development of the electric motor, electric railways, and electric elevators. His contributions were especially important in promoting urban development by increasing the size cities could reasonably attain and by allowing greater concentration of business in commercial sections. He became known as the "father of electric traction". Demonstrating an aptitude for science and mathematics, Sprague secured an appointment to the U.S. Naval Academy in 1874 and, after graduation in 1878 and 2 years at sea, resigned to pursue his career in electrical engineering.
Power engineering, also called power systems engineering, is a subfield of electrical engineering that deals with the generation, transmission, distribution, and utilization of electric power, and the electrical apparatus connected to such systems. Although much of the field is concerned with the problems of three-phase AC power – the standard for large-scale power transmission and distribution across the modern world – a significant fraction of the field is concerned with the conversion between AC and DC power and the development of specialized power systems such as those used in aircraft or for electric railway networks. Power engineering draws the majority of its theoretical base from electrical engineering and mechanical engineering.
The American Institute of Electrical Engineers (AIEE) was a United States-based organization of electrical engineers that existed from 1884 through 1962. On January 1, 1963, it merged with the Institute of Radio Engineers (IRE) to form the Institute of Electrical and Electronics Engineers (IEEE).
Edward Hibberd Johnson was an inventor and business associate of American inventor Thomas Alva Edison. He was involved in many of Edison's projects, and was a partner in an early organization which evolved into General Electric. When Johnson was Vice President of the Edison Electric Light Company, a predecessor of Con Edison, he created the first known electrically illuminated Christmas tree at his home in New York City in 1882. Edward H. Johnson became the Father of Electric Christmas Tree Lights.
Edwin James Houston was an American author, electrical engineer, academic, businessman, and inventor.

Diehl was a contemporary of Thomas Edison and his inventions caused Edison to reduce the price of his incandescent bulb.
George May Phelps was a 19th-century American inventor of automated telegraphy equipment. He is credited with synthesizing the designs of several existing printers into his line of devices which became the dominant apparatus for automated reception and transmission of telegraph messages.
The first International Exposition of Electricity ran from 15 August 1881 through to 15 November 1881 at the Palais de l'Industrie on the Champs-Élysées in Paris, France. It served to display the advances in electrical technology since the small electrical display at the 1878 Universal Exposition. Exhibitors came from the United Kingdom, United States, Germany, Italy and the Netherlands, as well as from France. As part of the exhibition, the first International Congress of Electricians presented numerous scientific and technical papers, including definitions of the standard practical units volt, ohm and ampere.
Charles Ernest Spagnoletti MInstCE, MIEE was an electrical inventor and the first telegraph superintendent of the Great Western Railway (GWR). He also advised various railway companies on the use of electricity, signalling, and telegraphy.
The Electro-Dynamic Light Company of New York was a lighting and electrical distribution company organized in 1878. The company held the patents for the first practical incandescent electric lamp and electrical distribution system of incandescent electric lighting. They also held a patent for an electric meter to measure the amount of electricity used. The inventions were those of Albon Man and William E. Sawyer. They gave the patent rights to the company, which they had formed with a group of businessmen. It was the first company in the world formally established to provided electric lighting and was the first company organized specifically to manufacture and sell incandescent electric light bulbs.
The Chicago Lighting Institute was an educational and marketing association serving the lighting industry in the Midwest. The main aim of the institute was to acquaint architects, interior designers, electrical engineers, urban planners and the general public with the latest developments and applications in lighting. It was the first U.S. institution to promote appropriate use of light in the earlier years of the lighting industry.
