Who invented the radio wave?

-Was it Tessla or Marconi...give specific details and dates if possible.

I am also interested why Tessla was not so well known unlike Marconi, was he a reclusive man?

Thanks in advance.Heinrich Rudolph Hertz in 1888. You can google him to get more information.Ever since the universe started there was radio waves. If you mean who was the first person to use radio waves, it was Marconi in 1901.
Radio waves have existed since the beginning of the universe.
God. all the others just found it.
