High Quality Content by WIKIPEDIA articles! Thies Christophersen (27 January 1918 in Kiel ? 13 February 1997 in Molfsee), a farmer by upbringing, was a prominent German Holocaust denier.The widely-known phrase "Auschwitz lie" (German Auschwitzlüge) can be traced to Christophersen, whose 1974 brochure of that name disputed the existence of gas chambers at the Auschwitz concentration camp.Along with Christophersen's own writings, that brochure also contains further contributions and forewords from other Holocaust deniers, including the former lawyer and convicted violent criminal Manfred Roeder (classified as a terrorist in Germany) and the former judge Wilhelm Stäglich. Since 1993 the brochure has been included on a list of materials that may not be distributed to young people, as ruled by Germany's Federal Department for Media Harmful to Young Persons, due to its Holocaust-denying content. The foreword by Manfred Roeder was characterised by that department as inflammatory anti-Semitic propaganda, which constitutes an infringement of Germany's Volksverhetzung law (incitement to hatred).
