Marconi's radio patent, 1897. Italian engineer, physicist and inventor Guglielmo Marconi (1874-1937) had developed his first radio equipment by the age of 21. He patented his radio system and established the Marconi's Wireless Telegraph Company in London in 1897. In 1899 he made the first transmission across the English Channel and, in 1901, the first trans-Atlantic transmission. In 1909 he was awarded the Nobel Prize in Physics.
