Franz Halder (1900-1972) was a German military officer who played an important role during World War II. Born in Würzburg, Germany, Halder began his military career by joining the Bavarian army and later transitioned to the German army in 1935. As the Chief of the General Staff from 1938 to 1942, Halder was responsible for the planning and coordination of military operations. He was known for his meticulous attention to detail and strategic thinking. Despite initially supporting Adolf Hitler, Halder became disillusioned with his leadership and actively participated in the planning of the failed assassination attempt on Hitler’s life in 1944. After the war, Halder was captured by the Allies and interned for two years before being released. He spent the rest of his life writing and giving lectures about his experiences during the war.
