Rolf Hochhuth was a German author and playwright, best known for his 1963 drama The Deputy, which insinuates Pope Pius XII's indifference to Hitler's extermination of the Jews, and he remained a controversial figure both for his plays and other public comments and for his 2005 defense of British Holocaust denier David Irving.

The Deputy, a Christian tragedy, also published in English as The Representative , is a controversial 1963 play by Rolf Hochhuth which portrayed Pope Pius XII as having failed to take action or speak out against the Holocaust. It has been translated into more than twenty languages. The play's implicit censure of a venerable if controversial pope has led to numerous counterattacks, of which one of the latest is the 2007 allegation that Hochhuth was the dupe of a KGB disinformation campaign, later confirmed by both the Venona Project and Mitrokhin Files in declassification of the Soviet disinformation campaign Operation Seat 12. The Encyclopædia Britannica assesses the play as "a drama that presented a critical, unhistorical picture of Pius XII" and Hochhuth's depiction of the pope having been indifferent to the Nazi genocide as "lacking credible substantiation.". However, it has since been discovered that Pope Pius XII seems to have known about concentration camps.
