  1. Siemens & Halske AG (or Siemens-Halske) was a German electrical engineering company that later became part of Siemens. It was founded on 12 October 1847 as Telegraphen-Bauanstalt von Siemens & Halske by Werner von Siemens and Johann Georg Halske .

  2. In 1847, the 33-year-old precision mechanic Johann Georg Halske joined artillery officer Werner von Siemens in founding the firm Siemens & Halske. This move laid the corner stone for a global company that now looks back on 175 years of history.

  3. Siemens & Halske - Siemens Global. The Telegraphen-Bauanstalt von Siemens & Halske was initially a general partnership. The company was transformed into a limited partnership in 1890 and into a stock corporation in 1897. In 1966, Siemens & Halske AG was integrated into the newly established Siemens AG.

  4. After the first few years of success in business, the scientist and engineer in Werner von Siemens once again came to the fore. In 1866 he achieved his greatest accomplishment: the discovery of the dynamo-electric principle and the invention of a "dynamo-machine", its first practical application.

  5. 1865–1896: High-voltage engineering and major international projects. The invention of the dynamo machine and the completion of large-scale, technologically demanding projects earned Siemens & Halske international acclaim.

  6. The Siemens-Halske Sh.III was an 11-cylinder, air-cooled counter rotary engine developed in Germany during World War I. The engine was a development of the earlier 9-cylinder Siemens-Halske Sh.I.

    Siemens-Halske Sh3 (Randy Huff) Siemens-Halske differential rotaries featured opposite cylinder and crankshaft rotation at a maximum speed of 900 rpm. This resulted in an effective engine speed of 1,800 rpm while the slower propeller speed resulted in greater efficiency, and the slower cylinder rotational speed reduced gyroscopic effects and ...
