  Adventures in CyberSound: Appleton, Edward Victor
Appleton served as a professor (1924-36) of physics at King's College, University of London, taught (1936-39) at Cambridge University, and, while serving (1939-49) in the Department of Scientific and Industrial Research, aided in the development of radar and the atomic bomb.
Edward Victor Appleton was born in Bradford, England, on 6th September, 1892, the son of Peter and Mary Appleton.
Edward Appleton's scientific achievements were honoured by his election to the Royal Society (1927), a knighthood (1941) and the Nobel Prize in Physics (1947) 'for his investigations of the physics of the upper atmosphere, especially the discovery of the Appleton layer.'

  Edward Victor Appleton - Wikipedia, the free encyclopedia
Sir Edward Victor Appleton (September 6, 1892 – April 21, 1965) was an English physicist.
In his work, Appleton had observed that the strength of the radio signal from a transmitter a on a frequency such as the medium wave band and over a path of a hundred miles or so was constant during the day but that it varied during the night.

Sir Edward Victor Appleton was one of the key figures of the twentieth century who contributed to the knowledge of radio and the ionosphere and hence improved our knowledge of the way in which radio waves propagate in the HF portion of the spectrum.
Edward Appleton received a Nobel prize in 1947 for his work, the technique for which laid the foundations for the development of radar.
Additionally Appleton had observed that the strength of the radio signal from a transmitter a on a frequency such as the medium wave band and over a path of a hundred miles or so was constant during the day but varied during the night, rising and falling in a regular manner.

Appleton proved the existence of the reflective layer by using the BBC transmitter at Bournemouth in a similar experiment using a signal in which the frequency was varied in a controlled way.
By measuring the interference between the direct and reflected signals at Oxford during an experiment on the night of December 12 th 1924, Appleton and Barnett were able to determine that the height of the reflecting layer was at an altitude of 100km and ionospheric science was born.
Appleton was knighted in 1941 for his contributions to British military research and received the 1947 Nobel prize for physics for his 'Investigations into the upper layer of the atmosphere'.

 BBC - History - Sir Edward Appleton (1892 - 1965)
Edward Victor Appleton was born on 6 September 1892 in Bradford.
Appleton realised that this was the layer responsible for reflecting short wave radio round the world - 'the Appleton layer' - that now enables communication with Australia and America.
In 1947 Appleton was awarded the Nobel Prize for Physics and, two years later, moved to the University of Edinburgh to become principal and vice-chancellor, a position he held for the rest of his life.

 PSEWEB: Professor Peter Excell - Sir Edward Appleton Trust
Sir Edward Appleton, Nobel prizewinner, and widely recognized as the discoverer of the Ionosphere, was born in 1892 in the city of Bradford.
Appleton’s research with Bragg was destined to be very brief as both men volunteered for the armed forces at the outbreak of World War I. Appleton applied for a commission in the Royal Engineers but was frustrated by the long wait involved and hence joined an infantry battalion (the Sixth West York­shire) in August 1914.
Appleton devised an elegantly simple experiment to prove the existence of the layer, and to determine its height, by monitoring variations in signal strength as the fre­quency of a commercial transmitter was varied.

Commonwealth researchers working with Appleton in Britain all became leaders in the development of radiolocation in their home countries and Sir Robert Watson-Watt has stated that, but for Appleton's scientific work, radar would have come too late to have been of decisive use in the Battle of Britain.
Appleton was knighted in 1941, being created K.C.B., and he was a member of the Scientific Advisory Committee of the War Cabinet which, in 1941, advised the Government that the manufacture of an atomic bomb was feasible.
Appleton's work has similarly been recognized in India and Denmark, and in 1948 he was appointed by the Pope to the Pontificial Academy of Science.

 IEEE - Edward V. Appleton, 1892 - 1965
Edward V. Appleton, was born on 6 September 1892, in Bradford.
With the cooperation of the BBC, he applied FM to the Bournemouth transmitter and observed a beat between the signal reflected from what he later called the E layer and the outgoing signal, thus proving conclusively the existence of the ionosphere, as well as measuring its height.
Appleton was the recipient of numerous awards, including the Nobel Prize for Physics, the U. Medal of Merit, the Norwegian Cross of Freedom, and appointment to the French Legion of Honor and to the Pontifical Academy of Science.

He proved the existence of the Kennelly-Heaviside layer (now called the E layer) in the atmosphere, and the Appleton layer beyond it, and was involved in the initial work on the atom bomb.
Appleton was born in Yorkshire and educated at Cambridge.
By periodically varying the frequency of the BBC transmitter at Bournemouth and measuring the intensity of the received transmission 100 km/62 mi away, Appleton found that there was a regular fading in and fading out of the signals at night but that this effect diminished considerably at dawn as the Kennelly-Heaviside layer broke up.

Sir Edward Appleton was Wheatstone Professor of Physics at King's from 1924 to 1936.
His experiments in the 1920s established the existence of the layer in the upper atmosphere now known as the ionosphere, by using a transmitter to shoot radio waves 60 miles up to the layer and measuring the time taken for them to be reflected back from it.
Appleton was based at the Strand Campus, and in 1929 a small hut was built for him on the roof, where he worked in every kind of weather until the development of radio caused serious interference to reception in central London.

Educated at St. John's College, Cambridge, Appleton worked at the Cavendish Laboratory from 1920 until he was appointed Wheatstone professor of physics at King's College, University of London, in 1924.
He showed that radio waves of wavelength sufficiently short to penetrate the lower region of the ionosphere are reflected by an upper region (now known as the Appleton layer, or F2 layer).
In 1936 Appleton returned to Cambridge as Jacksonian professor of natural philosophy and in 1939 became secretary of the government's Department of Scientific and Industrial Research, where he worked on radar and the atomic bomb during World War II.
