Henry T King Jr., one of the last Nuremberg war crimes prosecutors died Saturday.
King, who was 89, was one of the last of about 200 US prosecutors at Nuremberg who helped bring 21 Nazi leaders to trial from 1945 to 1949.
He later joined forces with his former Nuremberg colleagues Whitney Harris and Benjamin Ferencz to help shape the creation of the International Criminal Court (ICC) in Rome.
The threesome successfully lobbied the delegates setting up the permanent ICC in 1998 to include the crime of waging aggressive war among the grounds for prosecution, although the court has yet to adopt an agreement on a definition of aggression and the conditions under which it could exercise its jurisdiction with respect to this crime.
In 1945 and 1946, the United States, Britain, France and the Soviet Union jointly prosecuted 21 Nazi officials. Eighteen of the 21 were convicted; 10 were hanged.
King was 26 when he worked on the second phase of the prosecution. He was assistant prosecutor at the trial of Erhard Milch, a German officer involved in the mistreatment and killing of slave labourers.
