The invention of the radio is credited to Guglielmo Marconi, an Italian inventor. He developed the first apparatus for long-distance radio communication in the mid-1890s.
Marconi's work was based on the theoretical underpinnings, discovery, and experimental investigation of radio waves by many scientists and inventors. His contributions to the development of wireless telegraphy led to him being awarded the Nobel Prize in Physics in 1909.
Reginald A. Fessenden, a Canadian inventor, was the first person to send audio (wireless telephony) using electromagnetic waves. He successfully transmitted audio over a distance of about a mile on December 23, 1900. Fessenden also made the first public wireless broadcast on Christmas Eve in 1906.
