ZEIT research: Was grandpa a Nazi?

Millions of Germans were in the Wehrmacht and the NSDAP, but many of their descendants knew nothing about it. Everyone has recently been able to search for relatives in the member files with just a few clicks. What does looking at one's own family reveal about the German culture of remembrance? When does reappraisal become an honest confrontation, when does it become just a calming ritual? And how does memory change when more and more Germans have no personal connection to the Nazi era, for example because their families only immigrated later?

In cooperation with DIE ZEIT.
