Inventors, Pioneers & Scientists
- Edwin H. Armstrong
- Inventor of Regenerative Circuit (1912), the Superheterodyne Circuit (1918), the Superregenerative Circuit (1922)
and the complete FM System (1933)...
- Alexander Graham Bell
- Eminent scientist, inventor, engineer and innovator who is credited with inventing the first practical telephone.
- Dr. Harold Henry Beverage
- Inventor of the Beverage antenna.
- Lee de Forest
- Inventor of the vacuum tube and sound motion pictures.
- Thomas Alva Edison
- The fourth most prolific inventor in history, holding 1,093 US patents in his name, as well as many patents in the
United Kingdom, France, and Germany. He is credited with numerous inventions that contributed to mass communication
and, in particular, telecommunications.
- Michael Faraday
- English chemist and physicist who contributed to the fields of electromagnetism and electrochemistry. The SI unit
of capacitance, the Farad, is named after him, as is the Faraday constant, the charge on a mole of electrons (about
96,485 coulombs).
- Philo T. Farnsworth
- Inventor of Electronic Television
- Ralph Hartley
- an electronics researcher. He invented the Hartley oscillator and the Hartley transform.
- Joseph Henry
- American scientist who, while building electromagnets, discovered the electromagnetic phenomenon of
self-inductance. He also discovered mutual inductance independently of Michael Faraday. The SI unit of
inductance, the Henry, is named in his honor.
- Heinrich Rudolf Hertz
- German physicist who clarified and expanded the electomagnetic theory of light was the first to
satisfactorily demonstrate the existence of electormagnetic waves. The SI unit Hertz (Hz) was established
in his honor by the IEC in 1930 for frequency, a measurement of the number of times that a repeated event
occurs per second (also called "cycles per sec" (cps)).
- Edward Kleinschmidt
- One of the inventors of the teleprinter, and was a prolific inventor who
obtained 118 patents in the course of his 101-year life.
- Mahlon Loomis
- An early wireless telegraph experimenter who claimed to have transmitted signals in October 1866
between two Blue Ridge Mountain-tops 14 miles apart in Virginia, using kites as antennas, but with
no independent witnesses present.[
- Guglielmo Marconi
- Italian inventor, best known for his development of a radio telegraph system.
- Hiram Percy Maxim
- Cofounder of the American Radio Relay League (ARRL) and inventor.
- James Clerk Maxwell
- Scottish theoretical physicist and mathematician. His most important achievement was classical electromagnetic theory.
- Harold C. Moore
- Inventor of the Quad antenna.
- Samuel F. B. Morse
- Inventor of several improvements to the Telegraph.
- Nikola Tesla
- Serbian inventor, mechanical engineer, and electrical engineer. The International System of
Units unit measuring magnetic field B (also referred to as the magnetic flux density and magnetic induction), the Tesla,
was named in his honor.
- Shintaro Uda
- Co-inventor of the Yagi-Uda antenna.
- Hidetsugu Yagi
- Co-inventor of the Yagi-Uda antenna.
U.S. Navy Radio Stations & Monitoring Sites
- Fleet Radio Unit, Melbourne (FRUMEL)
- FRUMEL was a United States-Australian-British signals intelligence unit, based in Melbourne, Australia during World
War II. It was one of two major Allied signals intelligence units, called Fleet Radio Units, in the Pacific theatres,
the other being FRUPAC...
- OP-20-G
- OP-20-G or "Office of Chief Of Naval Operations (OPNAV), 20th Division of the Office of Naval Communications, G Section
/ Communications Security", was the US Navy's signals intelligence and cryptanalysis group during World War II. Its mission
was to intercept, decrypt, and analyze naval communications from Japanese, German, and Italian navies...
- Otter Cliffs Radio Station
- Commissioned on August 28, 1917, under the command of Lt. Alessandro Fabbri.
- Station HYPO
- Station HYPO, also known as Fleet Radio Unit Pacific (FRUPAC) was the United States Navy signals monitoring and cryptographic
intelligence unit in Hawaii during World War II. It was one of two major Allied signals intelligence units, called Fleet Radio
Units in the Pacific theaters, along with FRUMEL in Melbourne, Australia...
- Winter Harbor, Maine
- Radio station of the United States Navy that operated from 1935 to 2002.
