Each of the four victorious Allies appointed its own prosecution counsel for the Nuremberg Trial. The Chief Prosecutors were:
- U.S.: Robert H. Jackson
- Great Britain: Sir Hartley Shawcross
- France: François de Menthon/Auguste Champetier de Ribes (ab Januar 1946)
- USSR: Roman A. Rudenko
Among the prosecution attorneys, Robert H. Jackson played a special role because he was deeply involved in the organization and design of the proceedings before the trial commenced.
