Werner von Siemens, der Begründer der modernen Elektrotechnik

The biography sketches Werner Siemens' character and upbringing, follows his technical education and early experiments, and recounts successive inventions and theoretical advances that shaped electrical engineering. It details his work on telegraph apparatus, the expansion of line networks including undersea cables, and the development of the dynamo with applications to electric railways and lighting. The text balances technical exposition with accounts of business organization, public engagement, and international projects, and reflects on scientific method, practical invention, and the creation and growth of the Siemens firm. Concluding sections gather memoir material, honors, and bibliographic references.
