AntonThumann was born in Pfaffenhofen an der Ilm, Bavaria, German Empire on 31-10-1912. In the 1930s Thumann joined the Nazi party (member no. 1,726,633) and the SS (member no. 24,444). He then served as a guard at Dachau concentration camp from 1933 onward. Starting in 1937, Thumann was employed in the Office of Guard Command and ascended to the rank of Protective Custody Camp Leader, Schutzhaftlagerführer, in 1940. By early August 1940 he transferred to Gross-Rosen concentration camp, which at the time was still a sub-camp of Sachsenhausen concentration camp. In early May 1941, Thumann became the Protective Custody Camp Leader of the now independent Gross-Rosen camp, under Commander Arthur Rödl Rödl ended his service in Ukraine as part of the occupation police before committing suicide with a hand grenade when defeat for Nazi Germany looked inevitable on 05 April 1945, aged 46.
From mid-February 1943 to March 1944 he began service as Protective Custody Camp Leader at the Majdanek concentration camp. Due to his sadistic tendencies and participation in selections, gassings and shootings, the prisoners called him the “Hangman of Majdanek”. According to eyewitness Jerzy Kwiatkowski , who was interned at Majdanek from March 1943 to July 1944, Thumann personally executed prisoners and Soviet prisoners of war. He owned a German Shepherd that he used to bite the inmates. Jerzy Kwiatkowski died age 59 on 30 december 1986 in Krakau.
For a few weeks between March and April 1944 Thumann was at Auschwitz-Birkenau. Thumann also appears in a series of photographs from an SS recreation camp, the Solahütte near Auschwitz, discovered in 2007. In one of the photos Thumann is pictured with Richard Baer, Josef Mengele, Josef Kramer and Rudolf Höss
Thumann then served as Protective Custody Camp Leader at Neuengamme concentration camp from mid-April 1944 until the end of April 1945. Often accompanied by his dog , he was very feared in Neuengamme due to a reputation for abuse of prisoners at Gross-Rosen and Majdanek. As the British Army closed in on Neuengamme, the SS began an evacuation of the prisoners to prison ships. During the evacuation, 58 male and 13 female resistance fighters from nearby Fuhlsbüttel concentration camp were selected to be brought to Neuengamme to be executed on the orders of the Higher SS and Police Leader Georg-Henning Graf von Bassewitz-Behr .After the war, Bassewitz was arrested in September 1945 and provided for the offences committed in the Fuhlsbüttel prison within the Hamburg Curiohaus processes tried by a British military court. after he was acquitted in August 1947 in the Curiohaus as a war criminal, he was transferred to the Soviet authorities on 16 September 1947. for the murder of the 45,000 civilians in the area of Dniepropetrovsk, he was sentenced to 25 years hard labour. He died two years later on 31-01-1949, age 48, in a labor camp in Eastern Siberia.
With the participation of Thumann, these prisoners were hanged between 21 and 23 April 1945 in a detention cell. After some of the doomed men continued to resist, Thumann threw a hand grenade through the cell window. Under the command of Thumann and SS Unterscharführer Wilhelm Dreimann , the last 700 prisoners remaining at Neuengamme were forced to dispose of bodies and cover up the traces of the camp. On 30 April 1945 the prisoners were then sent on a death march with the aim of reaching the area of the Flensburg government. Georg Gussregen was his untersturmführer at Gross-Rosen.
At the end of the war Thumann was arrested by the British occupation forces. Thumann was put on trial before a British military tribunal in the Neuengamme Trial in Hamburg. Thumann and 13 other defendants, including Wilhelm Dreimann and the Commandant of Neuengamme SS Standartenführer Max Pauly , were charged with war crimes and crimes against humanity. The court handed down a guilty verdict on 18 March 1946 and sentenced 11 of the 14 defendants to death by hanging on 3 May 1946, including Thumann
, Dreimann and Pauly. The death sentence was carried out by British executioner Albert Pierrepoint at Hamelin prison on 8 October 1946.[
