[edit] Biography
Hughes was born in London in 1831 and emigrated to the United States as a young man. He was an experimental physicist, mostly in the areas of electricity and signals. He also invented an improved microphone, which was a modification of Thomas Edison's carbon telephone transmitter. He revived the term "microphone" to describe the transmitter's ability to transmit extremely weak sounds to a Bell telephone receiver. He invented the induction balance (later used in metal detectors) and was one of the first in 1878 to transmit and receive using radio waves[1]). Despite Hughes' facility as an experimenter, he had little mathematical training. He was a friend of William Henry Preece.
Eight years before Heinrich Hertz and nearly two decades before Guglielmo Marconi had demonstrated anything, Hughes was already transmitting and receiving electromagnetic waves. At the time his work failed to satisfy colleagues’ demands for scientific method and proofs. James Clerk Maxwell's theories were not yet well received and Hughes' transmissions were wrongly assumed to be electromagnetic induction. His achievements went unrecognized for decades. Marconi knew Hughes through Preece.
Hughes patented his telegraph system[2] in the United States in 1855, and in less than two years, a number of small telegraph companies, including Western Union in early stages of development, united to form one large corporation — Western Union Telegraph Co. to carry on the business of telegraphy on the Hughes system. In Europe, Hughes’ Telegraph System became an international standard.
[edit] Music
At an early age, Hughes developed such musical ability that he is reported to have attracted attention of Herr Hast, an eminent German pianist in America who procured for him a professorship of music at St. Joseph’s College in Bardstown, Kentucky.
[edit] Awards
He became one of the most highly decorated inventors of his time. Honors included a Grand Gold Medal in 1867 awarded at the Paris Exhibition, the Royal Society gold Medal in 1885, and The Albert Gold Medal, Society of Arts in 1897. For his numerous inventions and discoveries, especially the Printing Telegraph and Microphone, Napoleon III awarded him a Chevalier of the Legion of Honour awarding him Commander of the Imperial Order of the Legion of Honour. He also was awarded: The Order of Saint Meurice and Saint Lazare (Italy), The Order of the Iron Crown (Austria) which carried with it the title of Baron, The Order of Saint Anne (Russia), The Noble Order of Saint Michael (Bavaria), Commander of the Imperial Order of the Grand Cross of the Medjidie (Turkey), Commander of the Royal and Distinguished Order of Carlos III (Spain), The Grand Officer’s Star and Collar of the Royal Order of Takovo (Servia), and Officer of the Royal Order of Leopold (Belgium)..
