OK, I just looked it up. For those of you who don't know:
Apparently Pernkopf was the dean of the medical school in Vienna, Austria during the Nazi occupation. The atlas was published in the 1930's, but 60 yrs later it was suggested that Pernkopf may have used Holocaust victims as models for his drawings. Pernkopf was a prominent Nazi and some of the original paintings bear a swastika.
An investigation into those claims concluded that it was 99% certain that the book contained no such drawings as the starving Holocaust victims would have been poor models.
Never heard of this before, but I guess there's always Grant's and Netter's, right.
