Who was the inventor of this "coils in radio transmitters"?

Marconi.

So this:

"A Magnifying Transmitter is an advanced version of Tesla's tesla coil, a
high power radio transmitter. Often cited as Tesla's greatest invention,
the
Magnifying Transmitter consisted of three coils: an air-core transformer
plus a third coil operated as a grounded-base quarter-wave waveguide. In
Colorado Springs, Nikola Tesla constructed the first "Magnifying
Transmitter". From:

is not true?

That may or may not be a true account of a particular transmitter, but
has no bearing on the question that you asked, not being the first
transmitter to incorporate a coil.

My question was:
"Now is 2012. Is " this curious apparatus" the "fundamental part of modern
radio"? Of course in form of the " variations of Tesla coils and Tesla
coil circuits".

In 1924 Marx invented the High Voltage Generator without coils.
Tesla Coil is also HVG.

So I modify may question: "Are in todays transmitters "variations of Tesla
coils" or the "variations of Marx generators".
Or "is possible to do the transmitter without coils"?
If Yes, when was the first?

None of the above.

Modern recievers and transmitters contain coils but by no stretch of the
imagination could they be called Tesla coils.
