Read the passage to answer the question:

The names of three men – an Englishman, a German, and an Italian stand out from the many who have opened up for us this new path of progress: James Clerk Maxwell, Heinrich Hertz, and Guglielmo Marconi Maxwell prophesied wireless, discovering its principles. Hertz discovered and demonstrated those waves which are its secret, and Marconi invented the instruments which put these ideas to practical use. A crowd of other brilliant men have made their different contributions. Sir Oliver Lodge came very near to doing what Marconi did; indeed, a year before Marconi invented his instrument, Lodge demonstrated the possibility of sending a signal by these Hertzian waves but turned aside under pressure from other work. Professor Righi, Marconi’s science master, experimented in the laboratory and showed young Marconi the potentialities Oliver Heaviside, the English telegraphic engineer, subsequently revealed to us the amazing fact that these wireless waves are thrown back to the earth from the two curious ‘mirrors’ which, moving in the depth of the sky hundreds of miles from the surface of the earth, act as a kind of double sounding board. These are but a few of the men whose work all over the earth has brought the miracle of wireless to its present stage. But the three names stand pre-eminent.
