The Father of the Microphone

16 May 2020  Sat

David Edward Hughes, one of the most decorated scientists of the period was born on 16th May 1831. He was the inventor of the carbon microphone, which was important to the development of telephony.

Hughes started his invention career in his early 20’s with the invention of the printing type telegraph instrument. Invented and used in America, it was also instrumental in the successful growth of the communications network of Europe.

His work on suppression of electrical interference and discovery of the carbon microphone led to improved telephone communications and experiments with his induction balance led to the metal detector. His wireless experiments for which he had invented a unique detector enabling him to receive a transmission over a distance of 500 yards with his mobile receiver in 1879-1880 are a tribute to his ingenuity.

Hughes was elected a Fellow of the Royal Society in June 1880 and won their Royal Medal in 1885. After Hughes' death, the Hughes Medal was created by the Royal Society in his honor. The above-shown stamp was issued to tribute him in 1990.
