Helmut Krausnick

Helmut Krausnick (19 February 1905 – 22 January 1990) was a German historian and writer. From 1959 to 1972, he was the head of the Institute of Contemporary History, a leading German research institute on the history of National Socialism.

Krausnick co-authored ''Die Truppe des Weltanschauungskrieges'', the 1981 work on the mass murder of Jews in the occupied territories of the Soviet Union by the ''Einsatzgruppen'', which was considered a milestone in Holocaust studies. It was also one of the first publications to challenge the myth of the "clean" Wehrmacht. Provided by Wikipedia
