Gertrud Wilhelmine von Hindenburg (born December 4, 1860 in Magdeburg, † May 14, 1921 in Hannover) was a German noblewoman and philanthropist. She was the wife of Paul von Hindenburg, the Chief of the German Army Command in the second half of the First World War and President of Germany.
Gertrud von Hindenburg was the daughter of the Prussian Major General Oskar von Sperling (1814-1872) and his wife Pauline of Klass. Her older brother was infantry general Kurt von Sperling (1850-1914).
Sometime in the mid-1870s Gertrud von Sperling met her future husband in Stettin, where he belonged to the General Command of the II Army Corps. On September 24, 1879, the two married in Stettin after Hindenburg's promotion to captain in 1878 had created the material conditions for a marriage. From the union four children were born: Irmengard Pauline (born November 14, 1880 † 1948), an unnamed still-born son (1881), Oskar Wilhelm (January 31, 1883, † February 12, 1960) and Anne Marie (born November 29, 1891 in Berlin, † April 8, 1978 in Hannover).
In his 1920 autobiography, Paul von Hindenburg praised Gertrud as "a loving wife, who through joy and sorrow faithfully and tirelessly worked with me and took care of me... My best friend and comrade". As well as being described by family relatives as "living for her family... a shield for her husband against any inconveniences or concerns", Gertrud von Hindenburg was also generally considered as someone of great wit and "better-read than her husband". She had a keen interest in theater, music, and painting, and corresponded with many prominent contemporaries, such as the industrialist and politician Walther Rathenau, whom shortly before her death she urged he accept the post of Foreign Minister.
Once married, Mrs. von Hindenburg accompanied her husband to his various relocations as troop commander and staff officer in Stettin, Karlsruhe, Berlin, Magdeburg and, finally, to Hanover after her husband's 1911 retirement. Upon her husband's reactivation during World War I and his rise to the highest military functions, Gertrud von Hindenburg took over mainly charitable works, such as personally caring for the war wounded and founding the Gertrud von Hindenburg Foundation for moral strengthening of German youth.
