Who invented television?

Reply Sun 9 Sep, 2007 08:17 pm
I have heard at various times that three different people invented television. Philo T Farnsworth, Vladimir Zworykin, and John Logie Baird. What is the straight dope on this?

I have also heard that Philo T Farnsworth was the father of television, but John Logie Baird was definately first past the post insofar as patenting his ideas so He gets the credit, never heard of Zworykin though, so theres a measure of MY ignorance.

Broadcasting Pioneers: The Many Innovators Behind Television History
Overview - Timeline of TV Development

Paul Gottlieb Nipkow - Mechanical Television History
German, Paul Nipkow developed a rotating-disc technology to transmit pictures over wire in 1884 called the Nipkow disk. This was the very first electromechanical TV scanning system. Nipkow's system was abandoned early in the history of TV for the electronic systems developed by later inventors.

John Logie Baird - Mechanical
John Logie Baird is remembered as being an inventor of mechanical television. Mechanical television, an earlier version of TV that was discontinued, was developed in late 1920s in England. During W.W.II, Baird developed the first color picture tube. Learn about Baird's mechanical television system.

Charles Francis Jenkins - Mechanical
What John Logie Baird did towards the development and promotion of mechanical television in Britain, Charles Francis Jenkins did for North America. Jenkins invented a mechanical television system called radiovision and claimed to have transmitted the earliest moving silhouette images on June 14, 1923.

The History of the Cathode Ray Tube
Electronic television is based on the development of the cathode ray tube, which is the picture tube found in modern TV sets. German scientist, Karl Braun invented the cathode ray tube oscilloscope (CRT) in 1897.

Vladimir Kosma Zworykin - Electronic Television History
Vladimir Kosma Zworykin invented the cathode-ray tube called the kinescope in 1929, a tube needed for TV transmission. Vladimir Kosma Zworykin also invented the iconoscope, an early television camera. See the personal photographs of television pioneer Dr. Vladimir Kosma Zworykin and his involvement with television history.

Starting a bi before Nipkow ... [from Britannica, "television." Encyclopædia Britannica. 2007. Encyclopædia Britannica Online. 10 Sept. 2007 , http://www.britannica.com/eb/article-9106102. ]

In 1880 a French engineer, Maurice LeBlanc, published an article in the journal La Lumière électrique that formed the basis of all subsequent television. LeBlanc proposed a scanning mechanism that would take advantage of the retina's temporary but finite retainment of a visual image. He envisaged a photoelectric cell that would look upon only one portion at a time of the picture to be transmitted. Starting at the upper left corner of the picture, the cell would proceed to the right-hand side and then jump back to the left-hand side, only one line lower. It would continue in this way, transmitting information on how much light was seen at each portion, until the entire picture was scanned, in a manner similar to the eye reading a page of text. A receiver would be synchronized with the transmitter, reconstructing the original image line by line.

Ancient Hindu Puranas describe Doora Darsana Yantras (televisions)
in ancient India. Most of what the modern science invented were
available in ancient India.
