Now the reliable transmission of clear voices and music was a reality. Later that same year American Lee DeForest invented the _, a vacuum tube that improved and amplified wireless signals. His listeners were in ships at sea and a few newspaper offices equipped to receive the transmission. His 1906 Christmas Eve broadcast from Brant Rock, a small New England coastal village, was the first public broadcast of voices and music. In 1903 Reginald Fessenden, a Canadian, invented the _, the first audio device permitting the reception of wireless voice transmissions. Marconi was satisfied with his advance, but other scientists saw the transmission of voices by wireless as the next hurdle, a challenge that was soon surmounted. With the financial and technical help of the British, Marconi successfully transmitted wireless signals across the English Channel in 1899 and across the Atlantic in 1901. ![]() England, with a global empire and the world's largest navy and merchant fleets, was naturally interested in long-distance wireless communication. His native Italy was not interested in his invention, so he used his mother's contacts in Great Britain to find support and financing there. His improvements over earlier experimental designs allowed him to send and receive telegraph code over distances as great as two miles by 1896. Marconi, however, is considered the "Father of Radio" because not only was he among the first to send signals through the air, but he was also adroit at gaining maximum publicity for his every success. Early Radio: Because both applied for patents within months of one another in the late 1890s, there remains disagreement over who "invented" radio, Eastern European immigrant Nikola Tesla or Guglielmo Marconi, son of a wealthy Italian businessman and his Irish wife. ![]()
