The trials were held in the city of Nuremberg, Bavaria, Germany, in 1945–46, at the Palace of Justice. The first and best known of these trials was the Trial of the Major War Criminals before the International Military Tribunal (IMT), which tried 25 of the most important captured leaders of the Third Reich, though several key architects of the war (such as Adolf Hitler, Heinrich Himmler, and Joseph Goebbels) had committed suicide before the trials began.

The initial trials were held from November 20, 1945 to October 1, 1946. The second set of trials of lesser war criminals was conducted under Control Council Law No. 10 at the US Nuremberg Military Tribunals (NMT); among them included the Doctors' Trial and the Judges' Trial. This article primarily deals with the IMT; see the Subsequent Nuremberg Trials for details on those trials.

Rudolf Walter Richard Hess, also spelled Heß (26 April 1894 – 17 August 1987), was a prominent Nazi politician who was Adolf Hitler's deputy in the Nazi Party during the 1930s and early 1940s. On the eve of war with the Soviet Union, he flew solo to Scotland in an attempt to negotiate peace with the United Kingdom, where he was arrested and became a prisoner of war. Hess was tried at Nuremberg and sentenced to life imprisonment, which he served at Spandau Prison, Berlin, where he died in 1987. After World War II Winston Churchill wrote of Hess, "He was a medical and not a criminal case, and should be so regarded."

On 27–28 September 2007, British news services published descriptions of disagreement between his Western and Soviet captors over his treatment and how the Soviet captors were steadfast in denying his release. In July 2011, the remains of Hess were exhumed from a grave in Bavaria after it became a focus of a pilgrimage for neo-Nazis.

Hess, the eldest of four children, was born in Alexandria, Egypt, to Fritz H. Hess, a prosperous German Lutheran importer/exporter from Bavaria, and Clara Hess (née Münch). The family lived in luxury on the Egyptian coast near Alexandria, and visited Germany often during the summers, allowing the Hess children to learn the German language and to absorb German culture. The family moved back to Germany in 1908, where Hess enrolled as a boarder at the Protestant School in Bad Godesberg. Hess showed aptitude in science and mathematics, and expressed interest in becoming an astronomer. However, his father wished him to continue the family business, Hess & Co., and in 1911 convinced Hess to study business for a year in Neuchâtel, Switzerland, at the Ecole Supérieure de Commerce.

Albert Speer (born Berthold Konrad Hermann Albert Speer; ; pronounced [ˈʃpeːɐ̯] ( listen); March 19, 1905 – September 1, 1981) was a German architect who was, for a part of World War II, Minister of Armaments and War Production for the Third Reich. Speer was Adolf Hitler's chief architect before assuming ministerial office. As "the Nazi who said sorry", he accepted responsibility at the Nuremberg trials and in his memoirs for crimes of the Nazi regime. His level of involvement in the persecution of the Jews and his level of knowledge of the Holocaust remain matters of dispute.

Speer joined the Nazi Party in 1931, launching him on a political and governmental career which lasted fourteen years. His architectural skills made him increasingly prominent within the Party and he became a member of Hitler's inner circle. Hitler commanded him to design and construct a number of structures, including the Reich Chancellery and the Zeppelinfeld stadium in Nuremberg where Party rallies were held. Speer also made plans to reconstruct Berlin on a grand scale, with huge buildings, wide boulevards, and a reorganized transportation system.
