Swedish doctors visited Nazi school

A newly discovered document seems to show that many Swedes - including doctors - visited a Nazi school during the 1930s.

Researcher Nils Hansson traced the school's guestbook and told Swedish radio news that he "was struck by the high number of Swedes in the guestbook."

The school, north of Berlin, was designed to spread Nazi ideas about medicine to German doctors - a profession that would play a crucial role in the Holocaust.

Subjects included eugenics, racial biology, euthanasia and the chemistry of poison gas warfare.
