IV. Baron von Holstein, The “Mystery Man” of the German Foreign Office 1890–1906
Though historians are still waiting for Holstein's papers, enough material has accumulated since his death in 1909 to attempt a sketch of the man who had the largest share in the control of German foreign policy from the fall of Bismarck in 1890 till his own retirement in 1906. During his lifetime his name was scarcely known even to his countrymen; but the Memoirs of his colleagues Otto Hammann and Baron von Eckardstein, to mention only the two principal witnesses, have thrown a flood of light on the Éminence Grise of modern Germany, who, like Père Joseph, loved to work in the dark and preferred the reality to the pomp of power.
