lyĕl`mō märkā`zā märkô`nē), 1874–1937, Italian physicist, celebrated for his development of wireless telegraphy (see radio radio, transmission or reception of electromagnetic radiation in the radio frequency range. The term is commonly applied also to the equipment used, especially to the radio receiver.

He confirmed J. C. Maxwell's electromagnetic theory and in the course of experiments (1886–89) produced and studied electromagnetic waves (known also as hertzian waves, or radio waves).

Experimenting with homemade apparatus, in 1895 he sent long-wave signals over a distance of more than a mile. He patented his system in England (1896) and organized a wireless telegraph company (1897) to develop its commercial applications. In 1899 he transmitted signals across the English Channel and in 1901 received in St. John's, N.L., the first transatlantic wireless signals, sent from his station at Poldhu, Cornwall. After World War I he concentrated on short waves, and c.1930 turned his attention to microwaves. He received, jointly with K. F. Braun Braun, Karl Ferdinand , 1850–1918, German physicist. Braun taught at the Univ. of Marburg, Strasbourg Univ., Karlsruhe's Technische Hochschule, and the Univ. of Tübingen before being named director of Physics institute at Strasbourg in 1895.
