Alfried Krupp was convicted at Nuremberg, got his property back in 1951, and left the firm to a foundation instead of his son

Alfried Krupp became sole owner of the Essen arms maker in 1943. On 1 January 1943 the firm employed about 25,000 prisoners of war, foreign civilians and forced labourers; historians put the wartime total at 100,000 or more. A US tribunal at Nuremberg tried him from 8 December 1947. On 31 July 1948 it sentenced him to 12 years and forfeiture of all his property for slave labour and plunder. On 31 January 1951 US High Commissioner John J. McCloy commuted the sentence and restored all of his property. He walked out of Landsberg prison in February 1951. The 1953 Mehlem Agreement required him to sell the coal and steel works by 1959; they were never sold. His only son Arndt renounced his inheritance in 1966 in return for a yearly 2 million marks^†. In 1967 Alfried ordered that his private and company assets go to a charitable foundation. He died on 30 July 1967, aged 59, and the foundation began work on 1 January 1968. Arndt died in debt on 8 May 1986, aged 48, with no children. In 2026 the Alfried Krupp von Bohlen und Halbach Foundation holds 20.93% of thyssenkrupp. In May 2026 it commented on paused talks between thyssenkrupp and Jindal International Steel. Since 2022 it has paid historians to study Alfried's role under Nazism.
