(18141882) was a pioneer in the manufacture of telegraph cables. He designed and built a wire covering machine which is now in the London Science Museum. By now, he was employing 23 people and (albeit reluctantly) found himself having to manage the business rather than be quite so'hands on'.
Soon, Henley was manufacturing and installing long lengths of Telegraph Cable. Some of his early notable achievements included. The City of London to Manchester.By the mid 1850's, substantial land telegraph links existed in many Countries and future growth depended to a large degree on linking the land networks by Submarine Telegraph Cable. Thus, the scene was set for an explosion in the cable making industry. Henley set up as a submarine cable maker in 1857 and by 1859; he had his own factory beside the Thames at North Woolwich. He went on to manufacture the shore ends of the Trans-Atlantic cable in 1865 and generally helped lay the foundations of modern communication, as we know it today. Henley died in 1882 but his legacy lives on in the Company, which still bears his name. The business, which we now know as WT Henley, was originally developed as the Engineering department for the then neighbouring Cable Company. This was where our early cable accessories were first developed. The Company historian at the time recalls it as'A pulsating throbbing town of machinery... Fittings for ISCO'S, Feeder Pillars, disconnecting Boxes, Cutouts and a whole manner of products were soon to be included in our expanding range of Cable accessories.
Amongst the one time employees of the Company was the thriller producer Alfred Hitchcock. Hitch' (as he was known) worked in the advertising department of Henley's london offices, writing short stories for the in house magazine (The Henley) and providing illustrations for product marketing, until leaving in 1919 to start his career in the movies.In 2006, his first story'GAS' was made into a short film by the French film director Sylvie Bolioli. This is an extremely rare & antique Henleys telegraph galvanometer made in London, England, during second half of XIX century (signed ´´LONDON´´ on dial). Portable galvanic single-needle instrument with button keys, it also served as a galvanometer for measuring current. Unlike his magneto-electric machines it was based on Henley's galvanometers and so needed galvanic cells. It was used by the Royal Engineers of the British Army. As with other single-needle instruments it transmitted the "European Alphabet". Really impressive museum piece impossible to find. Measures (including terminals) is: 11.2 centimeters X 9.1 centimeters X 5.7 centimeters. All defects not mentioned but visible in the pictures will be considered as described.
