Hertzian Wave Wireless Telegraphy

'Hertzian Wave Wireless Telegraphy' is an article discussing a type of telegraph—"spark telegraph" or "Marconi telegraph"— invented by Guglielmo Marconi, an Italian inventor and electrical engineer, known for his creation of a practical radio wave-based wireless telegraph system. This led to Marconi being credited as the inventor of radio, and he shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun "in recognition of their contributions to the development of wireless telegraphy".
