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: http://www.wordiq.com/definition/Magnifying_Transmitter

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.

Marconi tried to sell his communication system to the US army.
They refused to accept because the system would receive
from all ships simultaneously without selection.
Then he added selective tuneable circuits.

Tesla on the contrary polluted the whole radio band with his
broadband lightning towers and poked fun at those "Hertzian waves".
Tesla never understood and went bancrupt for senile stubborness.
