Guglielmo Marconi (1874-1937) was an Italian engineer and physicist who recorded the first transatlantic transmission of radio signals. Hertz before him had already transmitted and received radio signals in the microwave range over short distances. Marconi received the 1909 Nobel prize in physics for his achievement.
