Question: Who tracked down and arrested the longest-serving commandant of Auschwitz concentration and extermination camp?

full_context: Document 1: Sobibór extermination camp: Sobibór (or Sobibor , or , ] ) was a Nazi German extermination camp built and operated by the SS near the railway station of Sobibór during World War II, within the semi-colonial territory of General Government of the occupied Second Polish Republic. The camp was part of the secretive Operation Reinhard, which marked the deadliest phase of the Holocaust in German-occupied Poland. The camp was situated near the rural county's major town of Włodawa (called "Wolzek" by the Germans), 85 km south of the provincial capital, Brest-on-the-Bug (Brześć nad Bugiem in Polish). Its official German name was "SS-Sonderkommando Sobibór". Jews from Poland, France, Germany, the Netherlands, Czechoslovakia and the Soviet Union (including Jewish-Soviet POWs), were transported to Sobibór by rail. Most were suffocated in gas chambers fed by the exhaust of a large petrol engine. Up to 200,000 people were murdered at Sobibór and possibly more. At the postwar trial against the former "SS" personnel of Sobibór, held in Hagen two decades into the Cold War, Professor Wolfgang Scheffler estimated the number of murdered Jews totalled a minimum of 250,000. This would make it the fourth worst extermination camp, after Bełżec, Treblinka, and Auschwitz.
Document 2: Reinhard Heydrich: Reinhard Tristan Eugen Heydrich (] ) (7 March 1904 – 4 June 1942) was a high-ranking German Nazi official during World War II, and a main architect of the Holocaust. He was an SS-"Obergruppenführer und General der Polizei" (Senior Group Leader and General of Police) as well as chief of the Reich Main Security Office (including the Gestapo, Kripo, and SD). He was also "Stellvertretender Reichsprotektor" (Deputy/Acting Reich-Protector) of Bohemia and Moravia. Heydrich served as president of the International Criminal Police Commission (ICPC; later known as Interpol) and chaired the January 1942 Wannsee Conference, which formalised plans for the Final Solution to the Jewish Question—the deportation and genocide of all Jews in German-occupied Europe.
Document 3: Rudolf Hess: Rudolf Walter Richard Hess (Heß in German; 26 April 1894 – 17 August 1987), was a prominent politician in Nazi Germany. Appointed Deputy Führer to Adolf Hitler in 1933, he served in this position until 1941, when he flew solo to Scotland in an attempt to negotiate peace with the United Kingdom during World War II. He was taken prisoner and eventually was convicted of crimes against peace, serving a life sentence until his suicide.
Document 4: Sobibór Museum: The Sobibór Museum or the Museum of the Former Sobibór Nazi Death Camp (Polish: "Muzeum Byłego Hitlerowskiego Obozu Zagłady w Sobiborze" ), is a Polish state-owned museum devoted to remembering the atrocities committed at the former Sobibor extermination camp located on the outskirts of Sobibór near Lublin. The Nazi German death camp was set up in occupied Poland during World War II, as part of the Jewish extermination program known as the Operation Reinhard, which marked the most deadly phase of the Holocaust in Poland. The camp was run by the "SS Sonderkommando Sobibor" headed by Franz Stangl. The number of Jews from Poland and elsewhere who were gassed and cremated there between April 1942 and October 14, 1943 is estimated at 250,000; possibly more, including those who came from other Reich-occupied countries.
Document 5: Hanns and Rudolf: Hanns and Rudolf is a dual biography of Hanns Alexander and Rudolf Höss by the British-American journalist Thomas Harding.
Document 6: SS command of Auschwitz concentration camp: The SS command of Auschwitz concentration camp refers to those units, commands, and agencies of the German SS which operated and administered the Auschwitz concentration camp during World War II. Due to its large size and key role in the Nazi genocide program, the Auschwitz Concentration Camp encompassed personnel from several different branches of the SS, some of which held overlapping and shared areas of responsibility.
Document 7: The Holocaust in Poland: The Holocaust in German-occupied Poland was the last and the most lethal phase of the Nazi "Final Solution of the Jewish Question" ("Endlösung der Judenfrage") marked by the construction of death camps on German-occupied Polish soil. The genocide officially sanctioned and executed by the Third Reich during World War II, collectively known as the Holocaust, took the lives of more than three million Polish Jews. The extermination camps played a central role in the implementation of the German policy of systematic and mostly successful destruction of over 90% of the Polish-Jewish population of the Second Polish Republic.
Document 8: Odilo Globocnik: Odilo Globocnik (21 April 1904 – 31 May 1945) was an Austrian war criminal. He was a Nazi and later an SS leader. As associate of Adolf Eichmann, he had a leading role in Operation Reinhard, which saw the murder of over one million mostly Polish Jews during the Holocaust in Nazi extermination camps Majdanek, Treblinka, Sobibor and Belzec. Historian Michael Allen described him as "the vilest individual in the vilest organization ever known".
Document 9: Hanns Alexander: Hanns Alexander (6 May 1917 – 23 December 2006) was a German Jewish refugee who tracked down and arrested the Kommandant of Auschwitz Rudolf Höss.
Document 10: Alexander Donat: Alexander Donat also Aleksander Donat in Polish (1905 – 16 June 1983); a chemist by training, and journalist by profession; was a Holocaust survivor imprisoned at the Warsaw Ghetto during the occupation of Poland by Nazi Germany in World War II. He became an inmate of several Nazi forced labor and concentration camps and an eye witness to the Holocaust in Poland. After the war, Donat emigrated with his family to the United States, settling in New York City, and went on to write about his wartime experiences. He wrote "Jewish Resistance" (1964), "Holocaust Kingdom" (1965), and "The Death Camp Treblinka: a documentary" (1979), a series of memoirs devoted to these traumatic events.
Document 11: Auschwitz concentration camp: Auschwitz concentration camp (German: "Konzentrationslager Auschwitz" , ] , also "KZ Auschwitz " or "KL Auschwitz ") was a network of German Nazi concentration camps and extermination camps built and operated by the Third Reich in Polish areas annexed by Nazi Germany during World War II. It consisted of (the original camp), Auschwitz II–Birkenau (a combination concentration/extermination camp), (a labor camp to staff an IG Farben factory), and 45 satellite camps.
Document 12: Majdanek concentration camp: Majdanek, or KL Lublin, was a German concentration and extermination camp built and operated by the SS on the outskirts of the city of Lublin during the German occupation of Poland in World War II. Although initially purposed for forced labor rather than extermination, the camp was used to kill people on an industrial scale during Operation Reinhard, the German plan to murder all Jews within their own General Government territory of Poland. The camp, which operated from October 1, 1941, until July 22, 1944, was captured nearly intact, because the rapid advance of the Soviet Red Army during "Operation Bagration" prevented the "SS" from destroying most of its infrastructure, and the inept Deputy Camp Commandant Anton Thernes failed in his task of removing incriminating evidence of war crimes. Therefore, Majdanek became the first concentration camp discovered by Allied forces. Also known to the "SS" as "Konzentrationslager Lublin", Majdanek remains the best preserved Nazi concentration camp of the Holocaust.
Document 13: Adolf Eichmann: Otto Adolf Eichmann (] ; 19 March 1906 – 1 June 1962) was a German Nazi SS-"Obersturmbannführer" (lieutenant colonel) and one of the major organizers of the Holocaust. Eichmann was tasked by SS-"Obergruppenführer" (general/lieutenant general) Reinhard Heydrich with facilitating and managing the logistics involved in the mass deportation of Jews to ghettos and extermination camps in German-occupied Eastern Europe during World War II. In 1960, Eichmann was captured in Argentina by the Mossad, Israel's intelligence service. Following a widely publicised trial in Israel, he was found guilty of war crimes and hanged in 1962.
Document 14: Rudolf Höss: Rudolf Höss (also Höß, Hoeß or Hoess; 25 November 1901 – 16 April 1947) was a Nazi German "SS"-"Obersturmbannführer" (lieutenant colonel) and the longest-serving commandant of Auschwitz concentration and extermination camp in World War II. He tested and carried into effect various methods to accelerate Hitler's plan to systematically exterminate the Jewish population of Nazi-occupied Europe, known as the "Final Solution". On the initiative of one of his subordinates, SS-"Hauptsturmführer" (captain) Karl Fritzsch, Höss introduced pesticide Zyklon B containing hydrogen cyanide to the killing process, thereby allowing SS soldiers at Auschwitz to murder 2,000 people every hour. He created the largest installation for the continuous annihilation of human beings ever known.
Document 15: Heinrich Müller (Gestapo): Heinrich Müller (28 April 1900; date of death unknown, but evidence points to May 1945) was a German police official under both the Weimar Republic and Nazi Germany. He became chief of the Gestapo, the political secret state police of Nazi Germany, and was involved in the planning and execution of the Holocaust. He was known as "Gestapo Müller" to distinguish him from another SS general also named Heinrich Müller. He was last seen in the "Führerbunker" in Berlin on 1 May 1945 and remains the most senior figure of the Nazi regime who was never captured or confirmed to have died.
