This is one of the most fascinating aspects of the Shoah (Holocaust) I’ve ever seen.
Tkuma Center for Holocaust Studies, in Dnepropetrovsk, they have
a Wehrmacht (German Infantry) officer’s handbook guide to the Nuremberg Laws.
The chart was called the Mischling Test - which the Nazi's used under the Nuremberg Laws to check if you were Jewish, Aryan, or a "Mischling," a hybrid.
It shows a pseudo-scientific basis for racial identification. Only people with four German grandparents (four white circles in middle of the page) were of "German blood". A Jew is someone who descends from three or four Jewish grandparents (black circles in middle of the page). Then there were people of "mixed blood" of the "first or second degree." A Jewish grandparent was defined as a person who is or was a member of a Jewish religious community. Also includes a list of allowed marriages ("Ehe gestattet") and forbidden marriages ("Ehe verboten").
What's fascinating, I think, is that this isn’t an SS or Gestapo guidebook. This was an army officer’s handbook. Everyone in the Wehrmacht carried it.
This was the banality and evil of the Shoah.
