Siemens, C. William
| (1823-1883), German-born English engineer, was a pioneer in the steel and telegraph industries. By 1861, Sir William used the regenerative principle in his patent for an open-hearth furnace that was heated by gas produced from low-grade coal outside the furnace. This process, first used in glass making, eventually replaced the Bessemer process (1856) in steel making. Sir William Siemens was originally Karl Wilhelm Siemens, born April 4, 1823, Lenthe, Prussia (now Germany), and died Nov. 19, 1883, London. |
