The first diode was the Galena Cats Whisker. It was invented shortly after the development of radio, but I'm not sure by who.
Fleming's vacuum tube diode came shortly afterwards.

Who invented the zener diode?
Dr. Clarence Melvin Zener of Southern Illinois University invented the zener diode.
Who invented liquid crystal diode?
The term "liquid crystal diode" was invented by patent lawyers in late 1970's for the emerging liquid crystal display technology to rhyme with the then dominant light emitting diode display technology. The term is misleading as the liquid crystal cell is not a diode in the ordinary meaning of the word. Since then the incorrect term has been adopted to patents (over 600 patents describing liquid crystal cells as diodes) and scientific literature in addition to its misuse in lay-articles in internet.
What is a large slower acting diode?
it is a rectify diode
What is the difference between a 1N4007 diode and a 1N4007S diode what does the s do?
The difference in the 1N4007 diode and the 1N4007S diode is the voltage. The 1N4007S has a higher voltage but the meaning of the S is not listed.
What is schotty diode?
Its schotlky diode. schotlky diode is metal semi conducter junction. It has fast switchng speed. The cutting voltage of schotlky diode is about 0.2 volts.
Who invented the zener diode?

Who invented the led light bulb?
"Nick Holonyak, 75, invented the LED (light emitting diode) in the 1960s."
When were the vacuum tubes invented?
1904, a diode by Fleming.
When was light emitting diode invented?
Nick Holonyak Jr. had one of those bright ideas that lit up the world. In 1962, he invented the first practical red light-emitting diode (LED).
Where was the o l e d invented?
OLED (organic light-emitting diode) was invented by Eastman Kodak, an American multinational company.
Who invented the first semiconductor diode what it is called as and from which metal it is made up of?
The first modern semiconductor diode was made with germanium. These diodes were invented in ww2 for RADAR. But before that semiconductor diodes were made with galena (lead sulfide), copper oxide, and selenium. I have no idea which was "first".
Who invented schottky diode?
Walter H. Schottky then James Robert Baird US Patent 3463975
Who invented the first LED light bulb?
Thomas Edison invented light because he made light so why not bulbs
