Details

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.

Maxwell published A Treatise on Electricity and Magnetism in 1873, stimulating many people to experiment with wireless communication. Others experimented without the benefit of his theories. Several inventors/experimenters came across the phenomenon of electromagnetic waves before they were proven to exist but it was written off as electromagnetic induction at the time. The first systematic and unequivocal transmission of electromagnetic waves was performed by Heinrich Rudolf Hertz in his experimental proof of their existence, described in papers published in 1887 and 1890. Hertz famously considered these results as being of little practical value.

After Hertz’s work many people were involved in further development of the electronic components and methods to improve the transmission and detection of electromagnetic waves. Around the turn of the 20th century, Guglielmo Marconi developed the first apparatus for long distance radio communication.[1] On 23 December 1900, the Canadian inventor Reginald A. Fessenden became the first person to send audio (wireless telephony) by means of electromagnetic waves, successfully transmitting over a distance of about 1.6 kilometers, and six years later on Christmas Eve 1906 he became the first person to make a public radio broadcast.
