Hermann Julius Höfle (19 June 1911 – 21 August 1962) was an Austrian-born SS commander and Holocaust perpetrator during the Nazi era. Höfle was deputy to Odilo Globočnik during Aktion Reinhard.

On 11 January 1943 Höfle sent a message to SS-Obersturmbannführer Adolf Eichmann in Berlin that documented the total number of Jews killed in the four extermination camps during 1942 as 1,274,166 Wikipedia

After an extradition request on 9 July 1948 by the Polish government Höfle fled to Italy, where he lived under a false name until 1951. He returned to Austria and then West Germany where for five months in 1954 he was a paid informant for US Army Counterintelligence (CIC). He reported on the activities of former SS men and the extreme-right in southern West Germany. The CIC was aware of Höfle’s SS background but did not investigate his claim that he had taken part in “security work in Poland” during the war.

In January 1961 he was arrested by Austrian authorities. He hung himself before he could be tried
