Wilhelm Keitel
Wilhelm Bodewin Johann Gustav Keitel (German pronunciation: [ˈkaɪ̯tl̩]; 22 September 1882 – 16 October 1946) was a German field marshal and war criminal who held office as chief of the Oberkommando der Wehrmacht (OKW), the high command of Nazi Germany's Armed Forces, for most of the Second World War. In that capacity, Keitel was Germany's de facto war minister. He signed a number of criminal orders and directives that led to numerous war crimes.
Keitel's rise to the Wehrmacht high command began with his appointment as the head of the Armed Forces Office at the Reich Ministry of War in 1935. Having taken command of the Wehrmacht in 1938 Hitler replaced the ministry with the OKW and Keitel became its chief. He was reviled among his military colleagues as Hitler's habitual "yes-man".
After the war, Keitel was indicted by the International Military Tribunal in Nuremberg as one of the "major war criminals". He was found guilty on all counts of the indictment: crimes against humanity, crimes against peace, criminal conspiracy, and war crimes. He was sentenced to death and executed by hanging in 1946.
