What  French physicist and mathematician was involved in the invention of radio?
Invention of radio Many people were involved in the invention of radio as we know it today. Experimental work on the connection between electricity and magnetism began around 1820 with the work of Hans Christian Ørsted, and continued with the work of André-Marie Ampère, Joseph Henry, and Michael Faraday. These investigations culminated in a theory of electromagnetism developed by James Clerk Maxwell, which predicted the existence of electromagnetic waves.
Oliver Lodge Sir Oliver Joseph Lodge, {'1': ", '2': ", '3': ", '4': "} (12 June 1851 – 22 August 1940) was a British physicist and writer involved in the development of, and holder of key patents for, radio. He identified electromagnetic radiation independent of Hertz' proof and at his 1894 Royal Institution lectures (""The Work of Hertz and Some of His Successors""), Lodge demonstrated an early radio wave detector he named the "coherer". In 1898 he was awarded the "syntonic" (or tuning) patent by the United States Patent Office. Lodge was Principal of the University of Birmingham from 1900 to 1920.
