Question: What is the birth date of this Field Marshal during WWII, who created the Fall Martin plan?

full_context: Document 1: Operation Veritable: Operation "Veritable" (also known as the Battle of the Reichswald) was the northern part of an Allied pincer movement that took place between 8 February and 11 March 1945 during the final stages of the Second World War. The operation was conducted by Field Marshal Bernard Montgomery's Anglo-Canadian 21st Army Group, primarily consisting of the First Canadian Army under Lieutenant-General Harry Crerar and the British XXX Corps under Lieutenant-General Brian Horrocks. The U.S. Ninth Army was incorporated into the 21st Army Group. The objective of the operation was to clear German forces from the area between the Rhine and Maas rivers, east of the German/Dutch frontier, in the Rhineland. It was part of General Dwight D. Eisenhower's "broad front" strategy to occupy the entire west bank of the Rhine before its crossing. "Veritable" (originally called "Valediction") had been planned for execution in early January, 1945 when the ground had been frozen and thus more advantageous to the Allies. The Allied expectation was that the northern end of the Siegfried Line was less well defended than elsewhere and an outflanking movement around the line was possible and would allow an early assault against the industrial Ruhr region.
Document 2: Wilhelm Keitel: Wilhelm Keitel (22 September 1882 – 16 October 1946) was a German field marshal who served as Chief of the Armed Forces High Command ("Oberkommando der Wehrmacht" or OKW) in Nazi Germany during World War II. According to David Stahel, Keitel was "well known and [...] reviled as Hitler's dependable mouthpiece and habitual yes-man" among his military colleagues.
Document 3: Schlieffen Plan: The Schlieffen Plan (German: "Schlieffen-Plan" , ] ) was the name given after World War I to the thinking behind the German invasion of France and Belgium on 4 August 1914. Field Marshal Alfred von Schlieffen, the Chief of the Imperial Army German General Staff from 1891 to 1906, devised a deployment plan for a war-winning offensive, in a one-front war against the French Third Republic from 1905–06. After the war, the German official historians of the "Reichsarchiv" and other writers, described the plan as a blueprint for victory. German historians claimed that the plan had been ruined by "Generaloberst" (Colonel-General) Helmuth von Moltke the Younger, the Commander-in-Chief of the German army after Schlieffen retired in 1906, who was dismissed after the First Battle of the Marne (5–12 September 1914).
Document 4: Fall Martin: Fall Martin ("Case Martin") was a plan created by Field Marshal Gerd von Rundstedt in late 1944 during World War II. The plan envisaged a two-pronged attack aimed at the Allied forces in eastern Belgium and Luxembourg.
Document 5: Alfred Jodl: Alfred Josef Ferdinand Jodl (   ; 10 May 1890 – 16 October 1946) was a German general and war criminal during World War II, who served as the Chief of the Operations Staff of the Armed Forces High Command (Oberkommando der Wehrmacht).
Document 6: Operation Quicksilver (deception plan): Operation Quicksilver was a Second World War military deception. Undertaken by the Allies in 1944, the operation threatened an invasion of France in the Pas de Calais region through the simulation of a large Field Army in South East England. Quicksilver formed part of the Operation Fortitude deception, itself part of the strategic Operation Bodyguard plan. The key element of Quicksilver was the creation in German minds that "First United States Army Group" (FUSAG) commanded by General George Patton supposedly would land in the Pas-de-Calais for the major invasion of Europe, after the landings in Normandy had lured the German defenders to that front. (FUSAG was a genuine army group headquarters which later became Omar Bradley's 12th Army Group, but was given a fictitious role and many non-existent divisions for purposes of deception.)
Document 7: Alfred Jodl: Alfred Josef Ferdinand Jodl (   ; 10 May 1890 – 16 October 1946) was a German general and war criminal during World War II, who served as the Chief of the Operations Staff of the Armed Forces High Command (Oberkommando der Wehrmacht).
Document 8: Military career of Adolf Hitler: The military career of Adolf Hitler can be divided into two distinct portions of Adolf Hitler's life. Mainly, the period during World War I when Hitler served as a "Gefreiter" (lance corporal) in the Bavarian Army, and the era of World War II when Hitler served as the Supreme Commander-in-Chief of the Wehrmacht (German Armed Forces) through his position as Führer of Nazi Germany.
Document 9: Fritz Todt: Fritz Todt (4 September 1891 – 8 February 1942) was a German construction engineer, senior Nazi figure, who rose from "Inspector General for German Roadways" where he oversaw the construction of German Autobahnen ("Reichsautobahnen") to Reich Minister for Armaments and Ammunition where he led the entire war military economy. At the beginning of World War II he founded what Hitler named "Organisation Todt" a military engineering company which supplied industry with forced labor and administered all constructions of concentration camps in the late phase of the Third Reich. He died in a plane crash in 1942.
Document 10: Operation Bodyguard: Operation "Bodyguard" was the code name for a World War II deception plan employed by the Allied states before the 1944 invasion of north-west Europe. The plan was intended to mislead the German high command as to the time and place of the invasion. The plan contained several operations, which culminated in the tactical surprise of the Germans during the Normandy landings on June 6, 1944 (also known as D-Day) and delayed German reinforcements to the region for some time afterwards.
Document 11: Karl Dönitz: Karl Dönitz (sometimes spelt Doenitz) (] ; 16 September 1891 – 24 December 1980) was a German admiral who played a major role in the naval history of World War II. Dönitz briefly succeeded Adolf Hitler as the head of state of Germany.
Document 12: Gerd von Rundstedt: Karl Rudolf Gerd von Rundstedt (12 December 1875 – 24 February 1953) was a Field Marshal in the Wehrmacht of Nazi Germany during World War II.
Document 13: Erwin Rommel: Erwin Rommel (15 November 1891 – 14 October 1944) was a German general and military theorist. Popularly known as the Desert Fox, he served as field marshal in the Wehrmacht of Nazi Germany during World War II.
Document 14: Battle of the Frontiers: The Battle of the Frontiers was a series of battles fought along the eastern frontier of France and in southern Belgium shortly after the outbreak of World War I. The battles resolved the military strategies of the French Chief of Staff General Joseph Joffre with Plan XVII and an offensive interpretation of the German "Aufmarsch II" deployment plan by Helmuth von Moltke the Younger. The German concentration on the right (northern) flank, to wheel through Belgium and attack the French in the rear, was delayed by the movement of General Charles Lanrezac's Fifth Army towards the north-west to intercept them and the presence of the British Expeditionary Force (BEF) on his left flank. The Franco-British were driven back by the Germans, who were able to invade northern France. French and British rearguard actions delayed the German advance, allowing the French time to transfer their forces to the west to defend Paris, resulting in the First Battle of the Marne.
Document 15: Battle of the Bulge: The Battle of the Bulge (16 December 1944 – 25 January 1945) was the last major German offensive campaign on the Western Front during World War II. It was launched through the densely forested Ardennes region of Wallonia in eastern Belgium, northeast France, and Luxembourg, towards the end of World War II. The surprise attack caught the Allied forces completely off guard. American forces bore the brunt of the attack and incurred their highest casualties of any operation during the war. The battle also severely depleted Germany's armored forces, and they were largely unable to replace them. German personnel and, later, Luftwaffe aircraft (in the concluding stages of the engagement) also sustained heavy losses.
