Karl Dönitz (1891-1980) was a German naval leader who played a significant role in World War II. He served as the commander of the German Navy (Kriegsmarine) from 1935 to 1943 and as the President of Germany for a brief period from May 1945 until his arrest in June 1945. Dönitz was a proponent of submarine warfare and was instrumental in the development of wolfpack tactics, which were used extensively during the Battle of the Atlantic. Karl Dönitz in Hebrew is קארל דניץ (Karl Donitz). In French, he is known as Karl Dönitz, and in Spanish, he is referred to as Karl Dönitz. Dönitz's strategic innovations and leadership in submarine warfare had a profound impact on naval combat during World War II. After the war, he was tried and convicted of war crimes at the Nuremberg trials and sentenced to ten years in prison. His presidency of Germany was brief and largely symbolic, as it occurred during the final days of the Nazi regime.
