Günther Quandt, whose family became major shareholders of BMW 15 years after the war, was a member of the Nazi Party from 1933. After the election of Hitler, he was appointed to the position of Leader of the Armament Economy, which was a title given to industrialists who played a leading role in the Nazi war economy. Quandt's factories supplied ammunition, rifles, artillery and batteries for the Nazis and, it is claimed, used slave labourers from concentration camps in some of his factories.[14]

A documentary aired on German TV in 2007 claimed that Quandt not only used slave labour, but also sidestepped postwar recrimination. BMW itself was not implicated in the documentary, and the firm has made no comment about the Quandts, but claims to have confronted its own wartime history via independent research projects.[14] The Quandt family responded by pledging to fund a research project into the family's Nazi past and its role under the Third Reich.[15]

Former Danish freedom fighter Carl Adolf Sørensen (b. ca. 1927) has been asked to meet with the Quandt family and possibly receive compensation, but has repeatedly refused to do so on the grounds that it is too late. In 1943, as a 17-year-old, he and 39 other resistance fighters were sent to Germany where they worked with dangerous chemicals, some dying within a few months, and only four of the group were still alive as of May 2009.
