a German family of scientific entrepreneurs and engineers. Ernst Werner von Siemens (1816-92) was an electrical engineer who developed the process of electroplating, devised an electric generator which used an electromagnet, and pioneered electrical traction. His brother Karl Wilhelm (1823-83) (also known as Sir Charles William Siemens) moved to England, where he developed the open-hearth steel furnace and designed the cable-laying steamship Faraday. Their brother Friedrich (1826-1904) applied the principles of the open-hearth furnace to glass-making.
