A Nobel Prize winner, Marconi was a pioneer in the early development of radio. In the early 1920s, Marconi believed he received signals from another world.
But what fascinated Marconi about the signals was the fact that they seemed to repeat the Morse code for the letter "V." It seemed highly unlikely to him that a natural source would use Morse code. In fact, Marconi himself had used Morse code for the letter "V" many years previously in one of his first wireless tests. Could the strange signals be sending his own code back to him?
