Data from Wikipedia -
Oskar Ritter von Niedermayer (8 November 1885 – 25 September 1948) was a German General, professor and a German super-spy. Sometimes referred to as the German Lawrence (just like Wilhelm Wassmuss), Niedermayer is remembered for having led the 1915–1916 Persian and Indo-German-Turkish mission to Afghanistan and Persia during World War I in an endeavor to incite the Emir Habibullah Khan to attack British India, as a part of the Persian and Hindu German Conspiracy as an adjunct to the German War effort. Between the World Wars, Niedermayer was associated with the Universities of Munich and Berlin.
