Anton Geiser (surname also spelled Geisser;[1] October 17, 1924 – December 26, 2012) was a Yugoslav-born member of the SS-Totenkopfverbände during World War II, who served as a guard at both the Sachsenhausen and Buchenwald concentration camps.
In 2006 he was stripped of his citizenship on the grounds that it would not have been granted had the full details of his role in the German military been known;[5] in 2010 a US judge ordered him deported to Austria, the country from which he had immigrated.
[10] On September 29, 2006, US District Court Judge David S. Cercone of Pittsburgh, Pennsylvania, ordered the revocation of Geiser's US citizenship,[1][11] citing Title 8 Chapter 12 § 1451(a) of the US Code,[5] which states that citizenship should be revoked and the certificate of naturalization canceled "on the ground that such order and certificate of naturalization were illegally procured or were procured by concealment of a material fact or by willful misrepresentation".
[12] In support of the illegal procurement claim, he cited Fedorenko v. United States, which specifically established the precedent that voluntary or involuntary assistants of Nazi persecutions were not eligible for US visas, and therefore that the revocation verbiage of the law applies.
[5] "Without Anton Geiser and other members of the SS Death's Head guard battalions, the Nazi concentration camp system could not have accomplished its diabolical objectives," said Eli M. Rosenbaum,[6] Director of Human Rights Enforcement Strategy and Policy in the Human Rights and Special Prosecution Section (HRSP), echoing the court's opinion: "As an armed concentration camp guard in World War II, Geiser 'personally advocated or assisted in the persecution of a group of persons because of race, religion, or national origin.'
Therefore, we will affirm the District Court's order granting the Government's motion for summary judgment and revoking Geiser's citizenship.
