He is credited with helping reveal the existence of the Wannsee Protocol
, the 1942 conference during which Nazi officials met to coordinate the genocide against the Jews, which they termed "The Final Solution." Kempner cited a few Rosenberg diary excerpts in his memoir, and in 1956 a German historian published entries from 1939 and 1940.
There are another sixty pages of primary source documents, which range from the Wannsee Protocol
and Hitler's decision to invade Russia to a Roosevelt Fireside Chat, popular articles, and oral accounts by soldiers and civilians on all sides of the war.
So the Wannsee Protocol
was drawn up to focus famed German efficiency on the business of murder.
Roseman compounds these basic errors by stating that such things happened in the `lawless conditions behind the military front' and how this was so very different from the `project expressed in the [January 20th, 1942] Wannsee Protocol
of systematically extracting and murdering Jews all across Europe'.
