Description / Descripción
- Siemens Metallurgy 1850. Siemens had been trained as a mechanical engineer, and his most important work at this early stage was non-electrical; the greatest achievement of his life, the regenerative furnace. Though in 1847 he published a paper in Liebig's Annalen der Chemie on the 'Mercaptan of Selenium,' his mind was busy with the new ideas upon the nature of heat which were promulgated by Carnot, Clapeyron, Joule, Clausius, Mayer, Thomson, and Rankine. He discarded the older notions of heat as a substance, and accepted it as a form of energy. Working on this new line of thought, which gave him an advantage over other inventors of his time, he made his first attempt to economise heat, by constructing, in 1847, at the factory of John Hick, of Bolton, an engine of four horse-power, having a condenser provided with regenerators, and utilising superheated steam. Two years later he continued his experiments at the works of Messrs. Fox, Henderson, and Co., of Smethwick, near Birmingham, who had taken the matter in hand. The use of superheated steam was attended with many practical difficulties, and the invention was not entirely successful; nevertheless, the Society of Arts, in 1850, acknowledged the value of the principle, by awarding Siemens a gold medal for his regenerative condenser. In 1859 William Siemens devoted a great part of his time to electrical invention and research; and the number of telegraph apparatus of all sorts – telegraph cables, land lines, and their accessories – which have emanated from the Siemens Telegraph Works (at Charlton, SE London) has been remarkable. In 1872 Sir William Siemens became the first President of the Society of Telegraph Engineers which became the Institution of Electrical Engineers, the forerunner of the Institution of Engineering and Technology.
