Erich Johann Albert Raeder (24 April 1876 – 6 November 1960) was a German admiral who played a major role in the naval history of World War II. Raeder attained the highest possible naval rank, that of Grand Admiral, in 1939, becoming the first person to hold that rank since Henning von Holtzendorff. Raeder led the Kriegsmarine for the first half of the war; he resigned in 1943 and was replaced by Karl Dönitz. At the Nuremberg Trials he was sentenced to life in prison but was released early due to failing health.
