(Christopher Duffy, Red Storm on the Reich).The storm is over but the false data in the libraries are potentially worse ; did the German author Wolfgang Groeger translate works by this Ehren-something ?
Seems unlikely ; also, the scholar may consider reports of the American educators -- Red infested -- in the 1940-50's promoting the "works" of this Ehren-something, including the Amercian libraries abroad. Be not fooled by anoyone's cries abouot any "witch hunts" in the USA ; because there may have been mistakes but there certainly had been the most extreme enemy of the USA and of the entiry Humanity active in the USA then ;
It seems that some works attributed to Wolfgang Groeger may have been farbicated and planted in the USA, the reader. This is not yet over ; because the falsehoods may be there and any student may be prone to take them for the genuine publications. WPT.
