Oliver Heaviside changed the Face of Telecommunications

Oliver Heaviside changed the Face of Telecommunications

On May 18, 1850, English self-taught electrical engineer, mathematician, and physicist Oliver Heaviside was born. Heaviside adapted complex numbers to the study of electrical circuits, invented mathematical techniques for the solution of differential equations, reformulated Maxwell’s field equations in terms of electric and magnetic forces and energy flux, and independently co-formulated vector analysis. Oliver Heaviside suffered from scarlet fever as a child and had to deal with a hearing impairment since…
Clarence Hungerford Mackay connected the World

Clarence Hungerford Mackay connected the World

On April 17, 1874, American financier Clarence Hungerford Mackay was born. Mackay was chairman of the board of the Postal Telegraph and Cable Corporation and president of the Mackay Radio and Telegraph Company. He supervised the completion of the first transpacific cable between the United States and the Far East in 1904. He laid a cable between New York and Cuba in 1907 and later established cable communication with southern Europe…
Henri Gaston Busignies and the HuffDuff System

Henri Gaston Busignies and the HuffDuff System

On December 29, 1905, French engineer Henri Gaston Busignies was born. Busignies is best known for his contributions to radar, radio communication, and radio navigation. His invention (1936) of high-frequency direction finders (HF/DF, or “Huff-Duff“) permitted the U.S. Navy during World War II to detect enemy transmissions and quickly pinpoint the direction from which a radio transmission was coming. Henri Gaston Busignies was born in Sceaux, in suburban Paris, France, the…
Herbert Eugene Ives and the Ives-Stilwell Experiment

Herbert Eugene Ives and the Ives-Stilwell Experiment

On November 13, 1953, US-American scientist and engineer Herbert Eugene Ives passed away. Ives headed the development of facsimile and television systems at AT&T. He is best known for the 1938 Ives–Stilwell experiment, which provided direct confirmation of special relativity’s time dilation, although Ives himself did not accept special relativity, and argued instead for an alternative interpretation of the experimental results. Herbert Eugene Ives studied at the University of Pennsylvania…
Karl Jansky and the Discovery of Cosmic Radio Waves

Karl Jansky and the Discovery of Cosmic Radio Waves

On October 22, 1905, American physicist and radio engineer Karl Guthe Jansky was born. In August 1931 Jansky first discovered radio waves emanating from the Milky Way. He is considered one of the founding figures of radio astronomy. Karl Jansky was born the third of six children in what was then the Territory of Oklahoma where his father, Cyril M. Jansky, the descendent of Czech immigrants, was Dean of the College…
Andreas Osiander and Copernicus’ Revolutions

Andreas Osiander and Copernicus’ Revolutions

On October 17, 1552, German Lutheran theologian Andreas Osiander passed away. Osiander published a corrected edition of the Vulgate Bible in 1522 and oversaw the publication of the book De revolutionibus orbium coelestium (On the revolution of the celestial spheres) by Copernicus in 1543. Osiander pursued mathematics as a hobby and editted Cardano‘s Artis Magnae, which introduced the theory of algebraic equations. Andreas Osiander studied at the University of Ingolstadt…
Sir Rowland Hill and the Penny Post

Sir Rowland Hill and the Penny Post

On August 27, 1879, English teacher, inventor and social reformer Sir Rowland Hill passed away. Hill campaigned for a comprehensive reform of the postal system, based on the concept of Uniform Penny Post and his solution of prepayment, facilitating the safe, speedy and cheap transfer of letters. Hill later served as a government postal official, and he is usually credited with originating the basic concepts of the modern postal service, including…
Michael Pupin and the long-distance Phone Calls

Michael Pupin and the long-distance Phone Calls

On October 9, 1858, Serbian American physicist and physical chemist Michael Pupin was born, who is best known for his numerous patents, including a means of greatly extending the range of long-distance telephone communication by placing loading coils (of wire) at predetermined intervals along the transmitting wire (known as “pupinization“). Mihajlo Idvorsky Pupin was born in the village of Idvor (in the modern-day municipality of Kovačica, Serbia) in Banat, in…
Vladimir Zworykin’s Television System

Vladimir Zworykin’s Television System

On July 30, 1888, Russian inventor, engineer, and pioneer of television technology Vladimir Zworykin was born. Zworykin invented a television transmitting and receiving system employing cathode ray tubes. He played a role in the practical development of television from the early thirties, including charge storage-type tubes, infrared image tubes and the electron microscope. Vladimir Zworykin studied at the St. Petersburg Institute of Technology, under Boris Rosing. He assisted Rosing often with experimental work…
Robert Metcalfe and the Ethernet

Robert Metcalfe and the Ethernet

On May 22, 1973, Robert Metcalfe, by the time PhD student in electrical engineering working at Xerox PARC, wrote a memo describing a way to transmit data from the early generation of personal computers to a new device, the laser printer. He named the new network technology Ethernet after the disproven luminiferous ether as an “omnipresent, completely-passive medium for the propagation of electromagnetic waves“. Over time, Ethernet has largely replaced…
