Dozens of historians and researchers are accusing Volkswagen of trying to cover up the “dark pages” of its history in Nazi Germany, following the announcement Volkswagen’s longtime historian Manfred Grieger was leaving the company. Grieger has led Volkwagen’s efforts to research and reveal the company’s actions during World War II, when Volkswagen forced concentration camp prisoners to work in the auto factories. Volkswagen has denied Grieger was dismissed. This comes as Volkswagen has announced another historian, Christopher Kopper, has been commissioned to research the company’s actions in Brazil during the military dictatorship from 1964 to 1985, following a lawsuit alleging 12 Volkswagen workers critical of the dictatorship were tortured in a VW factory near São Paulo.
