In 1926, Hungarian engineer Kálmán Tihanyi designed a

television system utilizing fully electronic scanning and

display elements, and employing the principle of "charge

storage" within the scanning (or "camera") tube.

John Ambrose Fleming: Fleming invented the two-electrode

radio rectifier; or vacuum diode, which he calls an

oscillation valve. Based on Edison's lightbulbs, the valve

reliably detects radio waves. Transcontinental telephone

service becomes possible with Lee De Forest's 1907 patent

of the triode, or three-element vacuum tube, which

electronically amplifies signals.Nikola Tesla: Tesla granted a US patent for a system of

transmitting electrical energy and one for an electrical

transmitter.Guglielmo Marconi: Marconi picked up the first transatlantic

radio signal, transmitted 2000 miles from Marconi station in

Cornwall, England.James Clerk Maxwell: Maxwell theorized that changes in

electrical and magnetic forces are sending waves

spreading through space at 186,000 miles per second.

Light is made up of such waves, and others might exist at

different frequencies.Heinrich Hertz: Heinrich Hertz confirmed Maxwell's surmise

with an apparatus that used sparks to produce an

oscillating electric current; the current, in turn, generated

electromagnetic energy that caused matching sparks to

leap across a gap in a receiving loop of wire a few yards

away.

The Inventers

Before radio & television the public

had limited access to long distance

information around the world, so

they had no way of knowing what

happens (news, events, etc.). Tesla,

Marconi, Maxwell, and Hertz solved

this problem in: 1864, 1888, 1900,

and in 1901; by patenting for the

inventions, picking up the first

transatlantic radio signal, and

realizing that that changes in

electrical and magnetic forces send

waves spreading through space at

186,000 miles per second.

Hmmmm…

In the years 1864 and 1900, Tesla and Maxwell used

brainstorming to come up with ideas. Tesla came up with a

“system of transmitting electrical energy”, and an “electrical

transmitter.” Maxwell came up with the theory that changes in

electrical and magnetic forces send waves spreading through

space at 186,000 miles per second.

Fleming, Maxwell, and Tihanyi did the

design step of the design process. Maxwell

theorized that changes in electrical and

magnetic forces send waves spreading

through space at 186,000 miles per second,

and Hertz proved him right. Fleming

designed the vacuum diode. A vacuum

diode is a two-electrode radio rectifier, and

it reliably detects radio waves. Tihanyi

designed a television system utilizing fully

electronic scanning and display elements,

and employing the principle of "charge

storage" within the scanning (or "camera")

tube.

Fleming built, Hertz evaluated, and Marconi tested. Fleming built the vacuum diode or two-electrode radio rectifier. Marconi picked up the first transatlantic radio signal. Hertz evaluated Maxwell’s theory and proved him right by using sparks to produce an oscillating electric current which generated electromagnetic energy that caused matching sparks to leap across a gap in a receiving loop of wire a few yards away.

Truly the first post war American

television was marketed in August,

1945 as a 1946 model. The president

of Viewtone, Mr. Irving Kane, was the

marketer of the television.
