	Riding on the Radio Waves - Part II Dream 2047 November issue (Site not responding. Last check: )
		Fleming called the device a diode because it contained two electrodes, the anode and the heated filament; he noted that when an alternating current was applied, only the positive halves of the waves were passed - that is, the wave was rectified (changed from alternating to direct current).
		Fleming's discovery was the first step to the amplifier tube that in the early part of the 20th century revolutionized radio communication.
		Fleming failed to appreciate the possibilities he had opened up and it was the American inventor Lee De Forest who in 1906 conceived the idea of interposing an open meshed grid between the heated filament and positively baissed anode, or plate, to control the flow of electrons.

	John Ambrose Fleming Biography (1849-1945)
		John Ambrose Fleming was the common thread that linked the work of three individual geniuses, yet every one of those three now overshadow him.
		Fleming, born on November 29, 1849, in Lancaster, England, was the son of a Congregational minister.
		Fleming named his invention the thermionic valve, the ancestor of all electronic tubes, because it controlled the flow of electricity just as a valve controls theflow of water.

		While Fleming was best known for inventing the thermionic valve, he also built the equipment which Guglielmo Marconi used to make the first transatlantic radio transmission in 1901.
		In addition, Fleming also advanced the teaching of electrical engineering, pioneering the method of laboratory teaching and devising the left- and right-hand rules still taught to schoolchildren today.
		Fleming died in 1945, bequeathing his collection to UCL, which is still used as a teaching resource today.

	Sir John Ambrose Fleming
		As part of the centenary celebrations marking the invention of the thermionic valve by Sir Ambrose Fleming, the veterans committee considered it appropriate to record the association that Fleming had with Guglielmo Marconi during the early years of the Marconi Company.
		Other achievements of Ambrose Fleming were a paper read in 1885 at the IEE on The Necessity for a National Standardising Laboratory for Electrical Instrumentation.
		Ambrose Fleming resigned as Scientific Advisor to the Marconi Company in October 1931 although he remained a consultant to the Company almost until his death.

	Fathom :: The Source for Online Learning
		The tale of the inventions of John Ambrose Fleming is sad.
		Fleming's valve was the first of a line of devices which were to be the mainstay of electronics for its first half of the twentieth century and well into the 'solid-state' era, when transistors and integrated circuits inspired the miniaturisation which we now expect.
		Fleming was already aware of de Forest's activities and had disputed the American's claims to originality through a sometimes acrimonious correspondence with him in the technical press in 1906.

	100 Years of Electronics Made Possible by the Vacuum Tube
		Fleming filed his patent application for a device he called an "oscillation valve." It was based on Thomas Edison's incandescent lamp, which had a filament in a glass bulb that had been evacuated of air.
		Fleming added a metal plate with a positive electric charge, transforming the light bulb into a device that regulates currents.
		Physicist Fred Dylla says the early 20th century inventor John Ambrose Fleming might be overwhelmed by the range of instruments and the pace of change today in the industry he helped create.

	No. 1323: Fleming's Electric Valve
		Radio was in its infancy, and the English scientist John Ambrose Fleming was working for the British "Wireless Telegraphy" Company.
		Fleming faced the problem of converting a weak alternating current into a direct current that could actuate a meter or a telephone receiver.
		Fleming realized that an Edison effect lamp would convert alternating current to a direct current because it let the electricity flow only one way.

	IEEE History Center - Fleming Valve Milestone
		Beginning in the 1880s Professor John Ambrose Fleming of University College London investigated the Edison effect, electrical conduction within a glass bulb from an incandescent filament to a metal plate.
		John Ambrose Fleming, a British scientist and professor at University College in London, is credited with what may be one of the most important developments in the history of electronics.
		Fleming used this phenomenon to rectify a weak wireless signal.

	The Vacuum Tube Situation by Elmer Cunningham
		Fleming at the time he applied for his patent, and at such time were not known to anyone else.
		While the Fleming patent is for a rectifier of high frequency currents only and did not specify the use of a local battery, Judge Mayer held that Fleming had the right to use his device in the ORDINARY detector circuits of the PRIOR ART.
		At Fleming's date (1905) amplifier and oscillating circuits were unknown, and as is well known to all radio engineers, it is impossible to substitute the two-member Fleming rectifier in the three-member audion amplifier and oscillating circuits and obtain the same results.

	Fleming
		Fleming had acted very much as Marconi's adviser in the design of his transmitter, although he did not use thermionic valves as Fleming had not yet invented them.
		Fleming, however, was a very busy man and also perhaps one who did not always see the immediate applications of the things on which he had worked.
		Fleming was the author of more than a hundred scientific papers and books, including the influential "The Alternate Current Transformer" (1889, 1892), "The Principles of Electric Wave Telegraphy" (1906), "The Propagation of Electric Currents in Telephone and Telegraph Conductors" (1911) and "Memoirs of a Scientific Life" (1934).
