Question: The 11th SS Panzer Army was formed by a man born in what year?
Context: Thomas Müller (born February 2, 1902, date of death unknown) was a German Waffen-SS officer who commanded the SS-NCO Training School (Waffen-SS-Unterführerschule) in Radolfzell, 9th SS Panzer Division "Hohenstaufen", 17th SS Panzergrenadier Division "Götz von Berlichingen" and the 6th SS Volunteer Sturmbrigade Langemarck during World War II.  He saw action on the East and the West, finishing the war on the Oder front. Walter Hauck (4 June 1918 – 6 November 2006) was a German SS officer infamous for the atrocities committed under his command during the Second World War.  Before the war, he worked in the German police.  By 1944, he had the rank of SS-Obersturmführer in the 12th SS Panzer Division Hitlerjugend and led the 2nd company of the 12th SS Reconnaissance Battalion.  In April 1944, he was responsible for the Ascq massacre in which 86 civilians were shot and the population brutalized after a railway sabotage.  In May 1945, accompanied by Hildegarde Mende, previously a guard in the Terezinstadt ghetto, he was responsible for another massacre in Leskovice, Czechoslovakia leading to the death of 26 civilians, including a 13-year-old boy, and the destruction of 31 houses. SS Panzer Brigade "Gross" was a unit of the Waffen-SS of Nazi Germany during World War II, under the command of Obersturmbannführer Martin Gross.  The brigade was formed from the SS Panzer Training and Replacement Regiment based in Dundaga, Latvia and the SS Panzer Troop Training Regiment "Seelager" based at the training grounds at Ventspils together with the SS Reconnaissance Training Battalion.  The brigade consisted of two infantry battalions, a panzer battalion of two companies with Panzer III and Panzer IV, a reconnaissance battalion, a StuG battalion, a pioneer company and a Flak company. Matthias Kleinheisterkamp (22 June 1893 – 29 April 1945) was an SS-"Obergruppenführer" during World War II.  He commanded the SS Division Totenkopf, SS Division Nord, SS Division Das Reich, III SS Panzer Corps, VII SS Panzer Corps, IV SS Panzer Corps, XII SS Army Corps and the XI SS Army Corps.  He was a recipient of the Knight's Cross of the Iron Cross with Oak Leaves. Operation Roland was a local German offensive inside the Soviet Union during the Second World War on the Eastern Front, and was conducted as a local operation within the overarching German summer offensive, Operation Citadel, on the southern side of the Kursk salient.  The German forces of the III Panzer Corps and the 2nd SS Panzergrenadier Division Das Reich of the II SS Panzer Corps attempted to envelop and destroy Soviet forces of the Voronezh Front.  This operation was necessitated by the failure of the German II SS Panzer Corps to break through Soviet forces during the Battle of Prokhorovka on 12 July.  Therefore, German commanders decided to first link up the III Panzer Corps, which had been lagging behind due to heavy Soviet resistance, with the II SS Panzer Corps, in order to consolidate the German positions into a continuous frontline without inward bulges and enable the two panzer corps to overrun Soviet forces defending Prokhoravka together.  The linking up of the two German pincers was planned to effectuate the envelopment of the Soviet 69th Army and other supporting units. Georg Keppler (7 May 1894 – 16 June 1966) was a high-ranking Waffen-SS commander during World War II.  He commanded the SS Division Das Reich, SS Division Totenkopf, I SS Panzer Corps, III SS Panzer Corps and the XVIII SS Army Corps. Kampfgruppe (or Battlegroup) Weidinger was a formation from the 2nd SS Panzer Division "Das Reich" that was formed to support the attack of II SS Panzer Corps at the tail end of Operation Epsom in the Normandy Campaign.  It took its name from the commander of the 4th SS Panzer-Grenadier Regiment "Der Führer", SS-Obersturmbannführer Otto Weidinger. The 6th Panzer Army ("6.  Panzer-Armee") was a formation of the German Army, formed in the autumn of 1944.  The 6th Panzer Army was first used as an offensive force during the Battle of the Bulge, in which it operated as the northernmost element of the German offensive.  The army was subsequently transferred to Hungary in early 1945 and used in both offensive and defensive actions there.  The final battles of the 6th Panzer Army were fought in Austria until the collapse of Nazi Germany, at which point the army was completely demoralized.  The remnants of the army eventually surrendered to the United States Army.  Army commander throughout the army's existence, SS-"Oberstgruppenführer" Josef Dietrich said in early 1945: "We call ourselves the "6th Panzer Army", because we've only got 6 Panzers left". The 11th SS Panzer Army ("SS-Panzer-Armeeoberkommando 11") was not much more than a paper army formed in February 1945 by Heinrich Himmler while he was commander of Army Group Vistula. 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.
