context_section_description: Siemens & Halske (S & H) was incorporated in 1897, and then merged parts of its activities with Schuckert & Co., Nuremberg in 1903 to become Siemens-Schuckert.  In 1907, Siemens (Siemens & Halske and Siemens-Schuckert) had 34,324 employees and was the seventh-largest company in the German empire by number of employees. (see List of German companies by employees in 1907)
  In 1919, S & H and two other companies jointly formed the Osram lightbulb company.
  During the 1920s and 1930s, S & H started to manufacture radios, television sets, and electron microscopes.
  In 1932, Reiniger, Gebbert & Schall (Erlangen), Phönix AG (Rudolstadt) and Siemens-Reiniger-Veifa mbH (Berlin) merged to form the Siemens-Reiniger-Werke AG (SRW), the third of the so-called parent companies that merged in 1966 to form the present-day Siemens AG.
  In the 1920s, Siemens constructed the Ardnacrusha Hydro Power station on the River Shannon in the then Irish Free State, and it was a world first for its design. The company is remembered for its desire to raise the wages of its under-paid workers only to be overruled by the Cumann na nGaedheal government.
