Guglielmo Marconi

Guglielmo Marconi
Inventor of the radio-signaling system, Italian electrical engineer Guglielmo Marconi was the first to send wireless signals across the ocean. Prior to his invention, there was no way to communicate over long distances without telegraph wires to carry electric signals. His equipment played a vital role in rescuing survivors of sea disasters such as the sinking of the Titanic. He won the Nobel Prize in physics in 1909 for his work in wireless telegraphy.
