HUGHES DAVID,EDWARD - INVENTOR, ENGINEER AND SCIENTIST

A brief biographical sketch of D. E. Hughes is presented. Hughes (1831-1900) was born in London. He was educated, and spent a short time working in America, where he developed and patented a novel form of printing telegraph which was adopted first in America and then throughout Europe. Once the printing telegraph was established in America, Hughes left and settled in London in 1857. He spent the next 20 years working on the general improvement of telegraphs and became an expert in identifying and curing interference due to electromagnetic crosstalk. At the end of this period he invented the microphone and the induction balance. Nowadays he is also remembered for some initial work in the field of wireless telegraphy.
