Henry Hunnings

from Wikipedia, the free encyclopedia

Henry Hunnings ( 1858--1935 ) was a British engineer from Rothwell, West Yorkshire in northern England.

Hunnings was instrumental in developing the microphone . In 1878 he was granted a patent for a new type of carbon microphone that used carbon rods instead of grains of carbon. The Bell Telephone Company later acquired Hunnings' patent and produced around 10,000 devices from it.
