13 February 2015 is: Radio Day
« on: 13 February, 2015, 10:29:40 AM »
UNESCO formally announced the formation of Radio Day in 2011;

 Guiglielmo Marconi sent the first ever radio transmission in 1896. Despite being known as “the father of radio”, he was only able to transmit radio signals, not voice. The first experiments with broadcasting voice transmissions did not occur until the early 1900s. But it was Nikola Tesla who was the real genius behind it and should have actually received the credit for inventing the radio.

Much as I like Tesla, if Marconi broadcast the first signal of any kind using radio then he invented it, broadcasting voice/music/anything else is icing and an extension of an original invention - a bit like tele going from colour to black and white or photos from glass slides to SD cards, you can reinvent the use but not the original 'thing'.

You echo my sentiments exactly re radio - tho I think the inventor of the first ever digital camera should be honoured quite separately from the inventor of the optical film version - ........now who were they?

They were Laura Digital-Camera of the Wellington Digital-Cameras and Norbert Optical-Film-Version of Stockholm.

Tesla is on record as saying he didn't mind if Marconi was credited with inventing radio, as long as he paid the royalties on Tesla's patents! But that was wireless telegraphy.

The Brazilian priest, Moura, was the first person to transmit sound successfully (1904) and was the first person to make something that we could recognise as a radio telephony set

Reginald Fessenden was the first person to make what would now be termed a radio broadcast (1906).

To me, the most fascinating thing about all these pioneers of radio is that they all studied at universities to learn the basis of their science, but none of them actually graduated and got a relevant degree. Then again, Wilbur Wright never obtained a pilot's licence ...

That's not how the attribution system works = the person credited as the inventor of something has to know what he is doing.  The first person to send a radio signal was a Mr Lodge, but he thought it worked by another magnetic effect, rather than radio waves, so he doesn't get credited as the inventor of radio.

Similarly, Mr TA Edison embedded an electrode into a light bulb and noted that current could flow via that electrode in one direction only.  He had discovered thermionic emission and the diode in one fell  swoop, but he couldn't find a practical use for it. 
Later, Mr Fleming found a use for a similar device in detecting the signals transmitted by Marconi. It was called a diode.

Because Fleming was the first person to use the diode for a practical purpose, he gets the credit for inventing the thing, although it  was substantially similar to Edison's modified light bulb.

 Edison gets the credit for inventing the light bulb, but only because he got a patent in a few hours before Mr Swan - and the two companies ended up together eventually. And thermionic emission is sometimes  called the Edison effect, because Edison did discover it, even if he didn't know what to do with it.

Hi CF, your first and last paragraphs are contradictory.

Any road up, here in the debating lounge things are there to kick about, swap opinions, all that jazz and although it may well not stand up in a court of law, it's still my opinion that whoever came up with something is the inventor of it.
Or, as some would have it, he who smelt it, dealt it.
