The Holocaust Memorial awarded the Righteous of the World post-mortem award to Nazi officer Wilm Hosenfeld. The Nazi was made popular by Roman Polanski’s movie, The Pianist, in which he saved a Jew.
In his free time from saving Szpilman, Hosenfeld interrogated Jewish resistance fighters in Warsaw, though Yad Vashem concluded refreshingly that there is no evidence implicating the Nazi in mass murders.
The Nazi should not have received the award also for a legal reason: it only goes to gentiles who risked their lives saving Jews. Hosenfeld exposed himself to no risk, and it was common among Germans even in death camps, to provide protekzia to a handful of Jews they deemed useful, professional, or respectable.
