Coruisk's radar set made by a firm that can be traced back in origin to the world renowned Professor William Thomson, later 1st Baron Kelvin of Largs. Lord Kelvin was professor of Natural Philosophy at the University of Glasgow from the age of 22 (1846) until 1899, after which he became Chancellor of the University. His influence on the world of science and technology was immense, ranging from the basic laws of thermodynamics to successful establishment the first transatlantic telegraph cable (for which he was knighted). He was also a keen sailor and kept a beautiful sailing boat, the Lalla Roohk) on the Firth of Clyde. In summer, he sailed her from his home, the sandstone mansion Netherhall at Largs on the Ayrshire Coast, to places as distant as Monte Carlo. Kelvin was an accomplished developer on scientific instruments, many of a maritime nature, and made fundamental improvements to the mariner's compass. The firm of Kelvin Hughes was established as an informal agreement between Glasgow instrument maker James White and Thomson to market and sell his many practical inventions. In 1900 the firm was formalised as Kelvin & James White Ltd and, after Lord Kelvin's death, it was renamed Kelvin, Bottomley & Baird when Kelvin's nephew James Thomson Bottomley joined the firm in 1913. For many years it operated from premises in Cambridge Street, Glasgow. The change to Kelvin & Hughes came in 1947 (for further details of the history of Kelvin Hughes see http://www.nahste.ac.uk/cgi-bin/view_isad.pl?id=GB-0248-UGD-033&view=basic) As a mark of Thomson's world eminence Queen Victoria enobled him in 1893, thus creating the first ever 'Lord of Science'. The title he chose, Baron Kelvin of Largs, linked his home and lifelong place of work. Kelvin resisted many attempts by leading academic establishments, prominently the world-renowned Cavendish Laboratory at Cambridge, to persuade him to move away from Glasgow. To commemorate Lord Kelvin's Golden Jubilee in the Chair of Natural Philosophy, the University of Glasgow invited eminent scientists from around the world to a period of celebratory events, one of which was a charter sailing on the Firth of Clyde aboard one of Coruisk's predecessors, the magnificent 1892 paddle steamer Glen Sannox. Lord Kelvin died at Netherhall in his 84th year (November 1907) while caring for Lady Kelvin who had recently suffered a stroke. After a service in St Columba's Episcopal Church on Largs seafront, Kelvin's body was taken to his beloved University for another service of remembrance in Bute Hall. Finally, in death, Kelvin left Glasgow forever, the body being taken by train to London where it was interred next to that of Sir Issac Newton in Westminster Abbey. Quite a story inspired by a radar set seen at Gourock pier!
