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.
Dramatic portrayals of Reinhard Heydrich number among the more numerous of any Second World War figure, comparable to Adolf Hitler as well as war films depicting Erwin Rommel.
 Reinhard Heydrich has been portrayed in both television and film, and was one of the few high ranking Nazis to be depicted in a dramatic film while the Second World War was still ongoing.
Heinz Siegfried Heydrich (29 September 1905 – 19 November 1944) was the son of Richard Bruno Heydrich and the younger brother of SS-Obergruppenführer Reinhard Heydrich.
 After the death of his brother, Heinz Heydrich helped Jews escape the Holocaust.
Erich Johann Albert Raeder (24 April 1876 – 6 November 1960) was a naval leader in Germany before and during World War II.
 Raeder attained the highest possible naval rank—that of "Großadmiral" (Grand Admiral) — in 1939, becoming the first person to hold that rank since Alfred von Tirpitz.
 Raeder led the "Kriegsmarine" (German War Navy) for the first half of the war; he resigned in 1943 and was replaced by Karl Dönitz.
 He was sentenced to life in prison at the Nuremberg Trials, but was released early due to failing health.
 Raeder is also well known for dismissing Reinhard Heydrich from the Reichsmarine in April 1931 for "conduct unbecoming to an officer and a gentleman".
Richard Bruno Heydrich (23 February 1865 – 24 August 1938) was a German opera singer (tenor), and composer.
 He was the father of SS Obergruppenführer and creator of the Final Solution Reinhard Heydrich, Heinz Heydrich and Maria Heydrich.
The service record of Reinhard Heydrich was a collection of official SS documents maintained at the SS Personnel Main Office in Berlin from 1934 until the fall of Nazi Germany in 1945.
 Most of Reinhard Heydrich's record was captured by the Allies and used for subsequent investigation into Heydrich's duties as head of the RSHA and overall performance in the SS in general.

Operation Anthropoid was the code name for the assassination of Schutzstaffel (SS)-"Obergruppenführer" and "General der Polizei" Reinhard Heydrich, head of the "Reichssicherheitshauptamt" (Reich Main Security Office, RSHA), the combined security services of Nazi Germany, and acting "Reichsprotektor" of the Protectorate of Bohemia and Moravia.
 The operation was carried out in Prague on 27 May 1942 after having been prepared by the British Special Operations Executive with the approval of the Czechoslovak government-in-exile.
 Wounded in the attack, Heydrich died of his injuries on 4 June 1942.
 His death led to a wave of merciless reprisals by German SS troops, including the destruction of villages and the killing of civilians.
 Anthropoid was the only successful assassination of a senior Nazi leader during World War II.
