Karl Dönitz (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 Nazi Germany.
On 30 April 1945, after the death of Adolf Hitler and in accordance with Hitler's last will and testament, Dönitz was named Hitler's successor as head of state, with the title of President of Germany and Supreme Commander of the Armed Forces. On 7 May 1945, he ordered Alfred Jodl, Chief of Operations Staff of the OKW, to sign the German instruments of surrender in Reims, France. Dönitz remained as head of the Flensburg Government, as it became known, until it was dissolved by the Allied powers on 23 May.
