Question: Who was one of the Hitler's food tasters who worked at the first Eastern Front military headquarters?
Context: "Führerhauptquartier" Wolfsschlucht I (Wolf's Gorge) was the codename for one of Adolf Hitler's military headquarters, located in a farmhouse of the Belgian village of Brûly-de-Pesche, in the municipality of Couvin, close to the French border.  It was occupied by Hitler between 6–24 June 1940 while awaiting the conclusion of the Battle of France. The Eastern Front (Modern Turkish: "Şark Cephesi" or "Doğu Cephesi") was one of the fronts of the Army of the Grand National Assembly during the Turkish War of Independence.  Its commanded all military units in Eastern Region.  At first, its headquarters was located at Erzurum, and moved to Sarıkamış, then Kars during the Turkish–Armenian War (which itself is usually referred to synecdochically as the Eastern Front of the Turkish War of Independence). Panzerschlachten ("Panzer Battles") is the German language title of Friedrich von Mellenthin's memoirs of his service as a staff officer in the Panzerwaffe of the German Army during World War II.  Aimed toward his Western audience of NATO military leadership who sought his counsel after the war, it was instrumental in forming the popular Western views of Eastern Front military operations up to the mid-to-late 1990s, when Soviet archival sources became available to Western and Russian historians.  Some of the content of his literary and theoretical output would go on to be embraced in elements of U.S. and NATO military doctrine.  This legacy is viewed as both positive and negative by different academics and military professionals. Heinrich Hitler (14 March 1920 – 21 February 1942), known as Heinz Hitler, was the son of Alois Hitler, Jr. and his second wife Hedwig Heidemann and the nephew of Adolf Hitler.  When World War II began, he joined the Wehrmacht and served on the Eastern Front, where he was captured and died in prison in 1942. Margot Wölk, sometimes written without "ö" as Margot Woelk (born 27 December 1917), is a German former secretary who was one of 15 young women who, in 1942, were selected to taste German leader Adolf Hitler's food at the Wolf's Lair in East Prussia for some two and a half years in order to confirm that the food was safe to eat and didn't contain any harmful toxins or poisons.  She was the only one of the 15 to survive World War II, and her background as Hitler's food taster was not revealed until a newspaper interview on her 95th birthday in December 2012. Operation Citadel (German: "Unternehmen Zitadelle" ) was a German offensive operation against Soviet forces in the Kursk salient during the Second World War on the Eastern Front that initiated the Battle of Kursk.  The deliberate defensive operation that the Soviets implemented to repel the German offensive is referred to as the Kursk Strategic Defensive Operation.  The German offensive was countered by two Soviet counter-offensives, Operation Polkovodets Rumyantsev (Russian: Полководец Румянцев ) and Operation Kutuzov (Russian: Кутузов ).  For the Germans, the battle was the final strategic offensive that they were able to launch on the Eastern Front.  As the Allied invasion of Sicily began Adolf Hitler was forced to divert troops training in France to meet the Allied threats in the Mediterranean, rather than use them as a strategic reserve for the Eastern Front.  Germany's extensive loss of men and tanks ensured that the victorious Soviet Red Army enjoyed the strategic initiative for the remainder of the war. Wolf's Lair (German: "Wolfsschanze"; Polish: "Wilczy Szaniec") was Adolf Hitler's first Eastern Front military headquarters in World War II.  The complex, which became one of several "Führerhauptquartiere" (Führer Headquarters) in various parts of eastern Europe, was built for the start of Operation "Barbarossa" – the invasion of the Soviet Union – in 1941.  It was constructed by Organisation Todt. Frente Leste (Portuguese for Eastern Front) was the name of the theater of Portuguese Armed Forces' anti-guerrilla operations in the East of Angola (by then a Portuguese overseas territory), during the Portuguese Colonial War (1961-1974).  After the success of the Portuguese military in the Eastern front by 1973, it started to be known as the Eastern Zone, since guerrilla warfare episodes were nonexistent.  Through economic and social promotion campaigns, including the construction of healthcare, education, sanitation, transport and security infrastructure, the construction of new villages, the training of new black military units like the Flechas, and the foreign units known as the Fiéis (former gendarmes from Zaire) and the Leais (refugees from Zambia), the Portuguese operations in the late stage of the anti-guerrilla war in Portuguese Angola, eradicated all the main sources of conflict in the territory. Führerhauptquartier Werwolf was the codename used for one of Adolf Hitler's World War II Eastern Front military headquarters located in a pine forest about 12 km north of Vinnytsia, in Ukraine, which was used between 1942 and 1943.  It was one of a number of "Führer" Headquarters throughout Europe, and the most easterly ever used by Hitler in person. "Führerhauptquartier" Wolfsschlucht II (English: "Wolf Canyon") or W2 was the codename used for one of Adolf Hitler's World War II Western Front military headquarters located in Margival, 10 km northeast of Soissons in the department of Aisne in France.  It was one of many other Führer Headquarters throughout Europe but was used only one time by Adolf Hitler, June 16 and 17, 1944 for a meeting with Field Marshals Rommel and von Rundstedt about the Normandy Front.
