Friedrich Siemens

Friedrich Siemens (born December 8, 1826 in Menzendorf , † May 24, 1904 in Dresden , full name: Friedrich August Siemens ) was a German entrepreneur from the Siemens family and a brother of Werner von Siemens .


As the eleventh child of the landlord Christian Ferdinand Siemens (1787–1840) and his wife Eleonore Henriette Deichmann (1792–1839), Friedrich was born as a so-called 7-month child, so his mental and physical development was very delayed. Since his parents died very early, Friedrich grew up with an uncle.

On January 24, 1864, Friedrich Siemens married Elise Witthauer, daughter of the forest and domain inspector Johann Georg Witthauer in Israelsdorf near Lübeck (* March 9, 1843; † July 22, 1919 Dresden). The couple had six children:

  • Walter: * December 21, 1864; † January 19, 1883 (from pulmonary tuberculosis)
  • Lisbet: * March 4, 1866; † April 24, 1947 in Dresden (on May 20, 1889, marriage to Prime Lieutenant Georg von Gersdorff )
  • Marie: * October 29, 1868; † March 16, 1875
  • Friedrich Carl Siemens : January 6, 1877; † June 25, 1952 ∞ Bertha Countess Yorck von Wartenburg (1899–1950), daughter of Count Heinrich , 4 children; from 1946–1948 he took over the chairmanship of the supervisory boards of Siemens & Halske AG and Siemens-Schuckertwerke AG for his temporarily interned nephew Hermann von Siemens . Parts of his private art collection ended up in the Soviet Union after the Second World War; they are now in the Hermitage (Saint Petersburg)
  • Werner Ferdinand Siemens: September 29, 1880; † September 25, 1915; Engineer in Dresden (April 25, 1908, marriage in Baden, Baden to Maria Cassinone née Dölling, born October 23, 1872 in Karlsruhe, † October 31, 1944 in Vienna), killed as a cavalry captain in the autumn battle in Champagne . He left two daughters: Katrin "Nini" Siemens (1909–1978) and Dorothea "Dorle" Siemens (1912–1987).
  • Wilhelm (Willi) Otto: August 7, 1882; † December 21, 1945 in Dresden

In contrast to his brother, he was not ennobled and therefore does not bear the Siemens name .

Siemens died in Dresden in 1904. His grave is in the New Annenfriedhof in Dresden-Löbtau. The grave figure was created by the sculptor Johannes Schilling .


When he was 15, he decided to be a cabin boy. Friedrich Siemens later worked for his brother's company in Great Britain . In 1856 he developed a regenerative smelting furnace with gas firing (see also Siemens-Martin furnace ). On December 2, 1856, he received British patent no. 2861 entitled "Improved Arrangement of Furnaces, which improvements are applicable in all cases where great heat is required" .

In 1856 he founded a furnace construction company in Dresden, which later became Friedrich Siemens Industrieofenbau (FSI). In 1862 his brother Hans Siemens founded the Dresden glass factory for the commercial exploitation of this invention.

In 1867 Friedrich Siemens took over the glass factory in Dresden- Löbtau from his late brother Hans . In 1868 the continuously operating furnace with regenerative firing for the mass production of glass was introduced. The production volume increased 66 times to two million bottles per month.

In 1871 a second glassworks was bought near Dresden. The royal "Friedrichshütte" (Dresdner Strasse in Freital-Döhlen ) founded by Adolf Theodor Roscher in 1822 was converted into a stock corporation after his death in 1861 and changed hands several times until Friedrich Siemens took over the factory. In 1879 a new branch was founded in Neusattl near Elbogen ( Bohemia ).

In 1874 the Dresden physician Friedrich Küchenmeister commissioned Siemens to build a crematorium oven . On October 9, 1874, the first ever cremation in a closed fire took place in Dresden in the regeneration furnace developed by Siemens (in what was then Siemens' glass factory in Dresden ).

In 1888, Friedrich Siemens converted his operations into a stock corporation. The joint stock company for the glass industry, formerly Friedrich Siemens , was created. In 1894 he leased the Seltersbrunnen in Niederselters and also the Mineralbrunnen Staatl. Fachingen , which his heirs ran until 1995. In 1958 they founded the company Siemens & Co. , which still produces Emser salt today.

In 1900 he received an honorary doctorate from the Technical University of Dresden . The short laudation read: “Because of his immortal merits, which he has earned through the inventions of the regenerative furnace for generating high temperatures, the furnace for melting glass, the regenerative burner for the production of brightly lit flames and the chemical regeneration of the heat of the flame gases from highly heated furnaces .
