Nazi Germany is the common English name for the period in German history from 1933 to 1945, when Germany was governed by a dictatorship under the control of Adolf Hitler and the Nazi Party (NSDAP).
 Under Hitler's rule, Germany was transformed into a totalitarian state in which the Nazi Party controlled nearly all aspects of life.
 The official name of the state was "Deutsches Reich" from 1933 to 1943 and "Großdeutsches Reich" ("Greater German Reich") from 1943 to 1945.
 The period is also known under the names the Third Reich (German: "Drittes Reich" ) and the National Socialist Period (German: "Zeit des Nationalsozialismus" , abbreviated as "NS-Zeit").
 The Nazi regime came to an end after the Allied Powers defeated Germany in May 1945, ending World War II in Europe.
Sicherheitsdienst (] , "Security Service"), full title Sicherheitsdienst des Reichsführers-SS (English: Security Service of the Reichsführer-SS ), or SD, was the intelligence agency of the SS and the Nazi Party in Nazi Germany.
 The organization was the first Nazi Party intelligence organization to be established and was considered a sister organization with the Gestapo , which the SS had infiltrated heavily after 1934.
 Between 1933 and 1939, the SD was administered as an independent SS office, after which it was transferred to the authority of the Reich Main Security Office ("Reichssicherheitshauptamt "; RSHA), as one of its seven departments/offices.
 Its first director, Reinhard Heydrich , intended for the SD to bring every single individual within the Third Reich's reach under "continuous supervision."
Heinrich Luitpold Himmler (] ; 7 October 1900 – 23 May 1945) was "Reichsführer" of the "Schutzstaffel" (Protection Squadron; SS), and a leading member of the Nazi Party (NSDAP) of Germany.
 Nazi leader Adolf Hitler briefly appointed him a military commander and later Commander of the Replacement (Home) Army and General Plenipotentiary for the administration of the entire Third Reich ("Generalbevollmächtigter für die Verwaltung").
 Himmler was one of the most powerful men in Nazi Germany and one of the people most directly responsible for the Holocaust.
Alfred Buntru (15 January 1887 – 23 January 1974) was a German academic and member of the Nazi Party.
 Born in Sankt Blasien in the Waldshut district of the Grand Duchy of Baden, he was educated at the Karlsruhe Institute of Technology.
 Buntru later became a professor of hydraulic engineering and a deputy "Reichsdozentenführer" (English: "Reich lecturer leader").
 He joined the Nazi Party in 1937 and the "Schutzstaffel" (SS) in 1938, attaining the SS rank of "Oberführer".
 As part of his SS membership, he was involved in the "Spitzeldienste", the network of political informants set up by the Nazi Party's intelligence organization, the "Sicherheitsdienst" (SD).
 Buntru survived the Second World War, and died in Aachen in 1974 at the age of 87.
SS-Anwärter ] is a German title which translates as “candidate” or "applicant".
 During the Third Reich, "Anwärter/SS-Anwärter" was used as a paramilitary rank by both the NSDAP and the SS.
 Within the Nazi Party, an "Anwärter" was someone who had been accepted into a government service position and the rank was issued in two degrees: one for party members and the other for non-party members.
 "Anwärter" was the lowest Nazi Party rank in a complex and extensive system of Nazi Party political ranks leading up to such positions as "Gauleiter" and "Reichsleiter".
Abteilungsleiter ("section leader"), German for department head, was also a mid-level administrative political position of the Nazi Party, often held by staff political officers attached to various "Gaue" throughout Germany.
 The position of Abteilungsleiter was not an actual Nazi Party political rank, but a title held by a Party member in addition to their formal rank.
 The position was first created in 1933, after the Nazis had secured power in Germany.
Reichsleiter (national leader or Reich leader) was the second highest political rank of the Nazi Party (NSDAP), next only to the office of Führer.
 "Reichsleiter" also served as a paramilitary rank in the Nazi Party and was the highest position attainable in any Nazi organisation.
The Personal Staff of the Reich Leader of the SS (German: "Hauptamt Persönlicher Stab Reichsführer-SS" ) was a main office of the SS which was established in 1933 by Heinrich Himmler to serve as a personal office coordinating various activities and projects subordinate to the "Reichsführer-SS".
Adolf Hitler, as Führer and Reich Chancellor and Supreme Commander of the Armed Forces of Nazi Germany, employed a personal staff, which represented different branches and offices throughout his political career.
 He maintained a group of aides-de-camp and adjutants, including Martin Bormann's younger brother Albert in the National Socialist Motor Corps (NSKK), Friedrich Hoßbach of the Wehrmacht, who was sacked for unfavourable conduct, and Fritz Darges of the "Schutzstaffel" (SS), who was also dismissed for inappropriate behaviour.
 Originally an SS adjutant, Otto Günsche was posted on the Eastern Front from August 1943 to February 1944, and in France until March 1944, until he was appointed as one of Hitler's personal adjutants.
Karl Wolff (13 May 1900 – 17 July 1984) was a high-ranking member of the Nazi SS who held the rank of SS-"Obergruppenführer" in the Waffen-SS.
 He became Chief of Personal Staff Reichsführer-SS (Heinrich Himmler) and SS Liaison Officer to Hitler until his replacement in 1943.
 He ended World War II as the Supreme Commander of all SS forces in Italy.
 In 1964, Wolff was convicted of war crimes in West Germany; he was released in 1969.
