Werner von Siemens

Werner von Siemens (1816–1892) was a German electrical engineer and industrialist who founded the firm that became Siemens AG. His inventions and businesses helped expand telegraphy and electrical engineering.

Carl Wilhelm Siemens: A German-born engineer and entrepreneur who helped develop the Siemens business in Britain. His brother built the company’s British operations and advanced its engineering work.
Pointer telegraph: An electric telegraph that displays transmitted letters by moving a pointer over a dial. Siemens and Halske’s early commercial success came from building this instrument.
Indo-European telegraph line: A nineteenth-century telegraph route connecting Europe with India through networks across several countries. Siemens & Halske helped construct this major international communications route.
Prussian Army: The land forces of the Kingdom of Prussia before the German Empire’s creation. Siemens served as an artillery officer, where technical work helped shape his engineering career.
William Siemens: The British name used by Carl Wilhelm Siemens, engineer and entrepreneur. This name appears in British accounts of the family’s engineering and industrial work.
Dynamo-electric machine: An electric generator that uses electromagnetic induction and self-excitation to produce current. Siemens’s self-excited dynamo made large-scale electrical generation more practical.
Electric railway: A railway whose trains receive electrical power from an external supply or onboard source. Siemens’s company demonstrated early electric rail transport and developed its infrastructure.
Prussian Patent Act of 1815: A Prussian law that regulated privileges granted for inventions and industrial processes. Siemens’s early patenting and commercial decisions unfolded within Prussia’s invention regime.
Friedrich von Hefner-Alteneck: A German engineer and inventor who worked for Siemens and designed electrical machinery. His designs extended the engineering enterprise Siemens had founded.
Self-excitation: A generator process in which residual magnetism initiates current that strengthens the machine’s magnetic field. This principle underpinned the practical dynamo Siemens presented in 1867.
