Ludwig August Theodor Beck (29 June 1880 – 20 July 1944) was a German general and the Chief of the General Staff of the Oberkommando des Heeres during the early years of the Nazi regime in Germany before World War II. He was also one of the leaders of failed 20 July plot against Hitler and was designated by fellow conspirators as future Head of State (Regent) after elimination of Hitler. The plot failed, however, and Beck was forced to commit suicide.
