	Vladimir Zworykin - Wikipedia, the free encyclopedia
		Although, as we know, Zworykin described cathode ray tubes as both transmitter and receiver, the operation, whose basic thrust was to prevent the emission of electrons between scansion cycles--a solution reminiscent of A.A. Campbell Swinton's proposal, published in Nature in December 1911.
		The demonstration given by Zworykin sometime late 1925, early 1926 (not in 1923, as popular accounts would have it) was far from a success with the Westinghouse management, even though it showed the possibilities inherent in a system based on the Braun tube.
		The breakthrough would come when the Zworykin team decided to develop a new type of cathode ray transmitter, one described in the French and British patents of 1928 priority by the Hungarian inventor Kalman Tihanyi whom the company had approached in July 1930, after the publication of his patents in England and France.

	Vladimir Zworykin - Who's Who in RCA VideoDisc
		Zworykin closed his eyes, reclined and said, 'Now it is time to go to work.' That is the way he went to work - by closing his eyes and dreaming and thinking and planning.
		Zworykin was born on July 30, 1889, in Mourom, Russia, where his father owned and operated a fleet of boats on the Oka River.
		Zworykin, or "The Doctor," which is the name by which many of us knew him, was unquestionably a great man; but I often wonder if any one of us, as an individual, is capable of appreciating the full measure of his genius.

	The My Hero Project - Vladimir Kosma Zworykinv_zworykin
		Zworykin filed his patent for color television that year, and Sarnoff gave him as much money as he said he needed, even during the Depression, when other departments were being closed.
		Zworykin's television system used a high-voltage cathode-ray tube and presented a 5-inch image that was bright enough to be viewed in a well-lit room.
		Zworykin stated, "The fate of television now rests in the laps of the financial and merchandising experts." David Sarnoff was on his way to realize his dream of putting a television in every home, but people were still going to have to wait for awhile.

	Appendix A: Who Invented Television
		Zworykin's corporate benefactor, David Sarnoff, believed the Iconoscope gave him the leverage he needed to bring all the legal might of RCA to bear on claiming Farnsworth's achievement as RCA's own.
		Still we read time and again that Zworykin made modern television possible when he "invented the Iconoscope for RCA in 1923." The facts are that Zworykin was not working for RCA in 1923, the Iconoscope did not exist at that time, and it is questionable whether Zworykin truly invented it at all.
		Zworykin got some momentum going with the Iconoscope, but it was not until the Image Orthicon tube was introduced that the industry had the tool it really needed to bring the world into our living rooms.

	Inventor of the Week: Archive
		One of the foremost figures in the complex history of television is Vladimir Zworykin, who invented the "iconoscope," "kinemascope," and "storage principle" that became the basis of TV as we know it.
		Zworykin made his way to Paris (1912), where he did work in x-rays and theoretical physics before emigrating to the US (1919).
		Zworykin continued his television work on his own time, and produced both the "kinescope," a more sophisticated cathode-ray picture tube, and the "iconoscope," the first all-electronic camera tube.

		What was worse than Zworykin's fraudulent claim to priority was that he visited Farnsworth's San Francisco laboratory in 1930 and stole the design for the image dissector.

		One of three men credited with the invention of television, Vladimir Zworykin had a Ph.D. in electrical engineering and spent years studying sophisticated technology on the cathode ray tube before he fled Russia for the United States in 1919.
		Zworykin already had demonstrated his "iconoscope" camera, based on a 1923 design, and his "kinescope" receiver when he met RCA's David Sarnoff.
		When Sarnoff asked the inventor what it would cost to continue his electronic scanning experiments and develop a marketable system, Zworykin allegedly replied, "$100,000 and a year and a half." From 1929 on, Zworykin worked for RCA, where Sarnoff pressed to bring the electronic television to market.
