He was born in Barrow-in-Furness, England. Barrow-in-Furness is an industrial town and Seaport in Cumbria, England. England is a Country which is part of the United Kingdom. Its inhabitants account for more than 83% of the total UK population whilst its mainland Following graduation from the Royal College of Science, London, in 1898, he became an assistant to Guglielmo Marconi, the Italian radio entrepreneur.

Originally known as the Kennelly-Heaviside layer, this region of the Earth's atmosphere became known as the Ionosphere. The Kennelly-Heaviside layer, also known as the E region or simply the Heaviside layer, is a layer of ionised Gas occurring at 90&ndash150 km The ionosphere is the uppermost part of the atmosphere, distinguished because it is Ionized by solar radiation In 1912 Eccles suggested that solar radiation was responsible for the observed differences in radio wave propagation during the day and night. Year 1912 ( MCMXII) was a Leap year starting on Monday (link will display the full calendar of the Gregorian calendar (or a Leap year starting Radio waves are electromagnetic waves occurring on the Radio frequency portion of the Electromagnetic spectrum. He carried out experiments into atmospheric disturbances of radio waves and used wave detectors and amplifiers in his work. Eccles invented the term Diode to describe an evacuated glass tube containing two electrodes; an anode and a cathode.

Following World War I Eccles' main interest was in electronic circuit development. World War I (abbreviated WWI; also known as the First World War, the Great War, and the War to End All In 1919 he worked in collaboration with F. W. Jordan to patent the flip-flop circuit, used in binary counters [1]. Year 1919 ( MCMXIX) was a Common year starting on Wednesday (link will display the full calendar of the Gregorian calendar (or a Common Frank Wilfred Jordan was a British physicist who together with William Henry Eccles invented the so-called " flip-flop "-circuit in 1918 In Digital circuits a flip-flop is a term referring to an Electronic circuit (a Bistable Multivibrator) that has two stable states and thereby Also in that year Eccles became vice-chairman of the Imperial Wireless Committee. He helped in the design of the first long wave radio station, and became involved in the early work of the British Broadcasting Company (later the BBC) following its establishment in 1922. The longwave Radio band is a range of frequencies used for AM broadcasting, which extends from 148 Year 1922 ( MCMXXII) was a Common year starting on Sunday of the Gregorian calendar.
William Eccles was a Fellow of the Royal Society (FRS). The Royal Society of London for the Improvement of Natural Knowledge, known simply as The Royal Society, is a Learned society for science that was founded in 1660 He was President of the Physical Society from 1928 to 1930, and President of the Institution of Electrical Engineers (IEE) in 1926.
