Friedrich Siemens was the eleventh child of Christian Ferdinand Siemens (1787–1840) and his wife Eleonore Henriette Deichmann (1792–1839). His parents died at an early age, and Friedrich grew up with an uncle.
Friedrich Siemens married Elise Witthauer. The couple had six children: Walter (21 December 1864 - 19 January 1883), Lisbet (4 March 1866 - 24 April 1947 in Dresden), Marie (29 October 1868 - 16 March 1875), Friedrich Carl Siemens (6 January 1877 - 25 June 1952), Werner Ferdinand Siemens (29 September 1880 - 25 September 1915) and Wilhelm (Willi) Otto (7 August 1882 - 21 December 1945 in Dresden).
In young years Siemens came to England. There he worked for the company of his brother Werner von Siemens. In 1856, Friedrich Siemens established his own company Friedrich Siemens Industrieofenbau in Dresden.
Siemens died in Dresden in 1904. His grave is located in the New Annenfriedhof in Dresden-Löbtau. The grave figure was created by the sculptor Johannes Schilling.
