Charles Proteus Steinmetz was an American mathematician and electrical engineer and professor at Union College. He fostered the development of alternating current that made possible the expansion of the electric power industry in the United States, formulating mathematical theories for engineers. He made ground-breaking discoveries in the understanding of hysteresis that enabled engineers to design better electromagnetic apparatus equipment, especially electric motors for use in industry.
Harry Nyquist was a Swedish-American physicist and electronic engineer who made important contributions to communication theory.
Arthur Edwin Kennelly was an American electrical engineer.
The Institute of Radio Engineers (IRE) was a professional organization which existed from 1912 until December 31, 1962. On January 1, 1963, it merged with the American Institute of Electrical Engineers (AIEE) to form the Institute of Electrical and Electronics Engineers (IEEE).
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).
Edith Clarke was an American electrical engineer. She was the first woman to be professionally employed as an electrical engineer in the United States, and the first female professor of electrical engineering in the country. She was the first woman to deliver a paper at the American Institute of Electrical Engineers; the first female engineer whose professional standing was recognized by Tau Beta Pi, the oldest engineering honor society and the second oldest collegiate honor society in the United States; and the first woman named as a Fellow of the American Institute of Electrical Engineers. She specialized in electrical power system analysis and wrote Circuit Analysis of A-C Power Systems.
This history of the telephone chronicles the development of the electrical telephone, and includes a brief overview of its predecessors. The first telephone patent was granted to Alexander Graham Bell in 1869.
Charles Felton Scott was an electrical engineer, professor at Yale University and known for his invention of the Scott-T transformer in the 1890s.
Benjamin Garver Lamme was an American electrical engineer and chief engineer at Westinghouse, where he was responsible for the design of electrical power machines. Lamme created an efficient induction motor from Nikola Tesla's patents and went on to design the giant Niagara Falls generators and motors and the power plant of the Manhattan Elevated Railway in New York City.
The IEEE Edison Medal is presented by the Institute of Electrical and Electronics Engineers (IEEE) "for a career of meritorious achievement in electrical science, electrical engineering, or the electrical arts." It is the oldest medal in this field of engineering. The award consists of a gold medal, bronze replica, certificate, and honorarium. The medal may only be awarded to a new leap/breakthrough in the technological area of science.
Lewis Buckley Stillwell was an American electrical engineer and the president of American Institute of Electrical Engineers (AIEE) from 1909 to 1910. He received the AIEE Lamme Medal (1933) and the AIEE Edison Medal (1935), for "his distinguished engineering achievements and his pioneer work in the generation, distribution, and utilization of electric energy." He also was inducted into the IEEE's Electrical Engineering Hall of Fame. His papers (1886-1939) are held in the Manuscript Division of the Princeton University Library. In 1898, he was elected to the American Philosophical Society. He was elected as a member of the National Academy of Sciences in 1921.
George Ashley Campbell was an American engineer. He was a pioneer in developing and applying quantitative mathematical methods to the problems of long-distance telegraphy and telephony. His most important contributions were to the theory and implementation of the use of loading coils and the first wave filters designed to what was to become known as the image method. Both these areas of work resulted in important economic advantages for the American Telephone and Telegraph Company (AT&T).
Pulse-code modulation (PCM) is a method used to digitally represent analog signals. It is the standard form of digital audio in computers, compact discs, digital telephony and other digital audio applications. In a PCM stream, the amplitude of the analog signal is sampled at uniform intervals, and each sample is quantized to the nearest value within a range of digital steps.
The World Wireless System was a turn of the 20th century proposed telecommunications and electrical power delivery system designed by inventor Nikola Tesla based on his theories of using Earth and its atmosphere as electrical conductors. He claimed this system would allow for "the transmission of electric energy without wires" on a global scale as well as point-to-point wireless telecommunications and broadcasting. He made public statements citing two related methods to accomplish this from the mid-1890s on. By the end of 1900 he had convinced banker J. P. Morgan to finance construction of a wireless station based on his ideas intended to transmit messages across the Atlantic to England and to ships at sea. His decision to change the design to include wireless power transmission to better compete with Guglielmo Marconi's new radio based telegraph system was met with Morgan's refusal to fund the changes. The project was abandoned in 1906, never to become operational.
Robert H. Park was an American electrical engineer and inventor, best known for the Park's transformation, used for simplifying the analysis of three-phase electric circuits. His related 1929 concept paper ranked second, when looking at the impact of all twentieth century power engineering papers. Park was an IEEE Fellow and a member of the National Academy of Engineering.
Roy Billinton is a Canadian scholar and a Distinguished Emeritus Professor at the University of Saskatchewan, Saskatoon, Saskatchewan, Canada. In 2008, Billinton won the IEEE Canada Electric Power Medal for his research and application of reliability concepts in electric power system. In 2007, Billinton was elected a Foreign Associate of the United States National Academy of Engineering for "contributions to teaching, research and application of reliability engineering in electric power generation, transmission, and distribution systems."
Herbert Bristol Dwight was an American-Canadian electrical engineer.
James John Smith was an Irish applied mathematician and electrical engineer. His career was mostly spent at General Electric (GE) in Schenectady, New York.
Maurice Leonard Sindeband was an American engineer, inventor, and executive. He was a former president of the Ogden Corporation.
Frank William Peek Jr. was an American electrical engineer and inventor, known as a pioneer in engineering research on the creation of extremely high voltage electricity. He is often given the sobriquet "inventor of man-made lightning". He is known for Peek's law.
