The Hanns-Joachim-Friedrichs-Award winning documentary film The Silence of the Quandts by the German public broadcaster ARD described in October 2007 the role of the Quandt family businesses during the Second World War. The family's Nazi past was not well known, but the documentary film revealed this to a wide audience and confronted the Quandts about the use of slave labourers in the family's factories during World War II. As a result, five days after the showing, four family members announced, on behalf of the entire Quandt family, their intention to fund a research project in which a historian will examine the family's activities during Adolf Hitler's dictatorship. The independent 1,200-page study that was released in 2011 concluded: "The Quandts were linked inseparably with the crimes of the Nazis"-Joachim Scholtyseck, the Bonn historian who compiled and researched the study. As of 2008 no compensation, apology or memorial at the site of one of their factories, have been permitted.
