Question: What was the nationality of the concentration camp commandant who was succeeded by Arnold Büscher?
Context: The Dachau subcamp at München-Schwabing was the first subcamp where concentration camp prisoners were permanently used as a labor force outside the main concentration camp.  Unlike most of the later subcamps which were constructed, organized, and managed by the SS Business Administration Main Office (WVHA) and the Dachau camp commandant, this subcamp's construction, administration, and organization was in the hands of Eleonore Baur, also known as Schwester Pia (Sister Pia).  This subcamp was also smaller than most others, and is included here as a representative case for instances in which prisoners were used by individuals or small organizations. Helen Jonas-Rosenzweig (born Helena Sternlicht; 25 April 1925) is a Holocaust survivor interned during World War II at the Kraków-Płaszów concentration camp where she was forced to work as a maid for SS camp commandant Amon Göth. 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. Amon Leopold Göth (] ; alternative spelling "Goeth"; 11 December 1908 – 13 September 1946;    ) was an Austrian SS-"Hauptsturmführer" (captain) and the commandant of the Kraków-Płaszów concentration camp in Płaszów in German-occupied Poland for most of the camp's existence during World War II.

He also served from April 1940 until September 1942 as the commandant of Neuengamme concentration camp, and later, from November 1943 until May 1944, as the fourth commandant of Majdanek concentration camp. Johannes Hassebroek (11 July 1910 in Halle, Saxony-Anhalt – 17 April 1977 in Westerstede) was a German SS officer of the Death's Head Units responsible for the Nazi concentration camps guardianship.  He became a concentration camp commandant with the rank of Major ("Sturmbannführer"). Otto Förschner (November 4, 1902 – May 28, 1946) was a German SS commander and a Nazi concentration camp official.  He served as commandant of the Mittelbau-Dora concentration camp and the Kaufering concentration camp in the Dachau camp system.  He was indicted for his crimes, found guilty and hanged in May 1946. Robert Karl Ludwig Mulka (12 April 1895, Hamburg – 26 April 1969, Hamburg) was an SS-"Obersturmführer".  At Auschwitz concentration camp, he was adjutant to the camp commandant, SS-"Obersturmbannführer" Rudolf Höss. Jan Sehn (April 22, 1909 – December 12, 1965), was a Polish lawyer, 1945-47 investigation judge, and professor at Jagiellonian University since 1961.  He was member of the Commission for the Investigation of Nazi War Crimes, and Chairman of the Kraków District Commission until 1953.  In 1945-46 he led the investigations on the site of the Nazi concentration camp Auschwitz-Birkenau.  As an investigation judge he prepared the accusation act of the former camp commandant Rudolf Höß.  From 1949 director of the Institute of Forensic Research in Kraków.  Sehn died suddenly 1965 in Frankfurt. Arnold Büscher (16 December 1899, Bad Oeynhausen – 2 August 1949) was a German SS officer.  At the rank of SS-"Obersturmführer", he was the second and last commandant of the Kraków-Płaszów concentration camp, succeeding Amon Göth, from September 1944 until about January 1945.
