Who invented the Television?

Answer 1

John Logie Baird

Although the development of television was the result of work by many inventors, Baird is one of its foremost pioneers. He is generally credited with being the first person to produce a live, moving television image in halftones by reflected light, among other major advances he later made in the field. Baird achieved this, where earlier experimenters had failed, by obtaining a better photoelectric cell and improving the signal conditioning from the photocell and the video amplifier.

In his first attempts to invent television, Baird experimented with the Nipkow disk, and demonstrated to the Radio Times that a semi-mechanical analogue television system was possible with the transmission of moving silhouette images, such as his fingers wiggling, in his London laboratory in February 1924. Baird gave the first public demonstration of moving silhouette images by television at Selfridges department store in London in a three-week series of demonstrations beginning March 25, 1925.

On October 2, 1925, John Logie Baird was successful in transmitting in his laboratory the first television picture with halftones: the head of a ventriloquist's dummy, in a 30-line vertically scanned image, at 5 pictures per second.[1] Baird went downstairs and fetched an office boy, 20-year-old William Edward Taynton, to see what a human face would look like. He became the first person to be televised in full tonal range.[2]

Answer 3

John Logie Baird gave the world's first public demonstration of a working television system that transmitted live moving images with tone graduation (grayscale) on 26 January 1926 at his laboratory in London, and built a complete experimental broadcast system around his technology. Baird further demonstrated the world's first color television transmission on 3 July 1928.

Answer 6

Here is a timeline of how TV was invented and by who:

Television was not invented by a single inventor, instead many people working together and alone over the years, contributed to the evolution of television.

1831 - Joseph Henry's and Michael Faraday's work with electromagnetism jumpstarts the era of electronic communication.

1862 - First Still Image Transferred
Abbe Giovanna Caselli invents his Pantelegraph and becomes the first person to transmit a still image over wires.

1873
Scientists May and Smith experiment with selenium and light, this reveals the possibilty for inventors to transform images into electronic signals.

1876
Boston civil servant George Carey was thinking about complete television systems and in 1877 he put forward drawings for what he called a selenium camera that would allow people to see by electricity. Eugen Goldstein coins the term "cathode rays" to describe the light emitted when an electric current was forced through a vacuum tube.

1880
Inventors Alexander Graham Bell and Thomas Edison theorize about telephone devices that transmit image as well as sound.
Bell's Photophone used light to transmit sound and he wanted to advance his device for image sending.

1884
18 Lines of Resolution
Paul Nipkow sends images over wires using a rotating metal disk technology calling it the electric telescope with 18 lines of resolution.

1906
First Mechanical Television System
Lee de Forest invents the Audion vacuum tube that proved essential to electronics. The Audion was the first tube with the ability to amplify signals. Boris Rosing combines Nipkow's disk and a cathode ray tube and builds the first working mechanical TV system.

1907 Early Electronic Systems
Campbell Swinton and Boris Rosing suggest using cathode ray tubes to transmit images. Independent of each other, they both develop electronic scanning methods of reproducing images.

1923
Vladimir Zworkin patents his iconscope a TV camera tube based on Campbell Swinton's ideas. The iconscope, which he called an electric eye becomes the cornerstone for further television development. Zworkin later develops the kinescope for picture display (aka the reciever).

1924/25
First Moving Silhouette Images
American Charles Jenkins and John Baird from Scotland, each demonstrate the mechanical transmissions of images over wire circuits.
John Baird becomes the first person to transmit moving silhouette images using a mechanical system based on Nipkow's disk.

1931
Charles Jenkin built his Radiovisor and 1931 and sold it as a kit for consumers to put together (see photo to right).

1926
30 Lines of Resolution
John Baird operates a television system with 30 lines of resolution system running at 5 frames per second.

1927
Bell Telephone and the U.S. Department of Commerce conduct the first long distance use of television that took place between Washington D.C. and New York City on April 9th. Secretary of Commerce Herbert Hoover commented, “Today we have, in a sense, the transmission of sight for the first time in the world’s history. Human genius has now destroyed the impediment of distance in a new respect, and in a manner hitherto unknown.”
Philo Farnsworth, files for a patent on the first complete electronic television system, which he called the Image Dissector.

Answer 9

John Logie Baird, a Scottish engineer

Answer 10

Alexander Graham Bell
Inventor
Name at birth: Alexander Bell

Born and educated in Scotland, Alexander Graham Bell was the son of Alexander Melville Bell. The Bell family emigrated to Canada in 1870, and in 1871 young Alexander moved to Boston, Massachusetts as a teacher to the deaf. He worked on ways to translate the human voice into vibrations, and came up with the idea for the telephone. In 1875 Bell began working with Thomas Watson, a mechanically-inclined electrician; by 1876 Bell had uttered the first intelligible sentence over the phone: "Mr. Watson, come here, I want you." Later in his career Bell worked on a variety of inventions, including flying machines and hydrofoils.
