Question: Who should be called the father of radio?

Disambiguated questions and answers:
context: Lee De Forest had an interest in wireless telegraphy and he invented the Audion in 1906. He was president and secretary of the De Forest Radio Telephone and Telegraph Company (1913). The De Forest System was adopted by the United States Government, and had been demonstrated to other Governments including those of Great Britain, Denmark, Germany, Russia, and British Indies, all of which purchased De Forest apparatus previous to the Great War. De Forest is one of the fathers of the "electronic age", as the Audion helped to usher in the widespread use of electronics.

context: On 1 June 1894, at a meeting of the British Association for the Advancement of Science at Oxford University, Lodge gave a memorial lecture on the work of Hertz (recently deceased) and the German physicist's proof of the existence of electromagnetic waves 6 years earlier. Lodge set up a demonstration on the quasi-optical nature of "Hertzian waves" (radio waves) and demonstrated their similarity to light and vision including reflection and transmission. Later in June and on 14 August 1894 he did similar experiments, increasing the distance of transmission up to 55 meters. In these lectures Lodge demonstrated a detector that would become standard in radio work, an improved version of Branly's detector which Lodge dubbed the "coherer". It consisted of a glass tube containing metal filings between two electrodes. When the small electrical charge from waves from an antenna were applied to the electrodes, the metal particles would cling together or "cohere" causing the device to become conductive allowing the current from a battery to pass through it. In Lodge's setup the slight impulses from the coherer were picked up by a mirror galvanometer which would deflect a beam of light being projected on it, giving a visual signal that the impulse was received. After receiving a signal the metal filings in the coherer were broken apart or "decohered" by a manually operated vibrator or by the vibrations of a bell placed on the table near by that rang every time a transmission was received. Lodge also demonstrated tuning using a pair of Leyden jars that could be brought into resonance. Lodges lectures were widely publicized and his techniques influenced and were expanded on by other radio pioneers including Augusto Righi and his student Guglielmo Marconi, Alexander Popov, Lee de Forest, and Jagadish Chandra Bose.

knowledge: content: Reflecting his pioneering work, De Forest has sometimes been credited as the "Father of Radio",[4][5][6] an honorific which he adopted as the title of his 1950 autobiography.

content: Edwin Howard Armstrong (December 18, 1890[2] – February 1, 1954[3]) was an American electrical engineer and inventor, who developed FM (frequency modulation) radio and the superheterodyne receiver system.

content: David Sarnoff (February 27, 1891 – December 12, 1971) was an American businessman and pioneer of American radio and television. Throughout most of his career he led the Radio Corporation of America (RCA) in various capacities from shortly after its founding in 1919 until his retirement in 1970.

content: Fessenden is best known for his pioneering work developing radio technology, including the foundations of amplitude modulation (AM) radio. His achievements included the first transmission of speech by radio (1900), and the first two-way radiotelegraphic communication across the Atlantic Ocean (1906).

long_answer: American electrical engineer and inventor Edwin Howard Armstrong should be called the father of radio because he developed FM radio and the superheterodyne receiver system. David Sarnoff, who led the Radio Corporation of America in various capacities, and Reginald Fessenden, who acheived the first transmission of speech by radio and the first two-way radiotelegraphic communication across the Atlantic Ocean, should be called the father of radio based on radio broadcasting. Lee de Forest titled his 1950 autobiography "Father of Radio," self pro-claiming himself with the title. Guglielmo Marconi and Jagdish Chandra Bose should be called the father of radio based on their research pioneering the invention of the radio.
