Karol Hochberg (1911–1944, also Karl or Karel) was a collaborator during the Holocaust, who led the "Department for Special Affairs" within the Ústredňa Židov, the Judenrat in Bratislava which was created by the Nazis to direct the Jewish community of Slovakia.
[2] In early 1941, the first head of the ÚŽ was deposed and arrested for sabotaging a census of Jews in eastern Slovakia with an aim to remove them to the west of the country.
The Working Group employed him as an intermediary despite its intense dislike and distrust of Hochberg, its fear that associating with him would harm their reputations, and its belief that he was unreliable.
[13] In November 1942, as the Working Group began to negotiate the Europa Plan with Wisliceny in an effort to save all European Jews from deportation and death, Hochberg was arrested for bribery and corruption.
[15] Imprisoned at Nováky labor camp[1] and later Ilava prison, Hochberg escaped during the Slovak National Uprising and joined the partisans.
