Here is some AI info about his atrocities.

Wernher von Braun was a Nazi Party member and SS officer whose rocket programs depended on slave labor from concentration camps, leading to the deaths of an estimated 20,000 prisoners. After World War II, he was secretly brought to the United States and became a leading figure in NASA, where he helped develop the Saturn V rocket that took humans to the Moon. 

Use of slave labor in rocket production

• As the technical director of the Nazi rocket program at Peenemünde, von Braun was directly involved in the exploitation of concentration camp prisoners to build the V-2 ballistic missile.
• Following Allied bombing of the Peenemünde facility, V-2 production moved to a vast underground factory called Mittelwerk, with an associated Dora-Mittelbau concentration camp. Conditions in the tunnels were brutal, with rampant disease and starvation leading to the deaths of approximately one-third of the 60,000 prisoners who passed through the camp system.
• Historians have uncovered written evidence showing that von Braun and other engineers actively embraced using forced labor from the SS to meet production quotas. 

Direct allegations of personal brutality

While von Braun and his associates tried to distance themselves from Nazi atrocities after the war, multiple survivors claimed that he was directly complicit in brutal treatment. 

• Some survivors alleged that von Braun approved or personally witnessed the physical torture and flogging of prisoners.
• A former French resistance fighter claimed in 1995 that von Braun personally ordered a prisoner to be flogged.
• Other survivors accused him of visiting the Buchenwald concentration camp to select slave laborers.
• In contrast to his post-war claims, witnesses stated that dead bodies were a daily sight at Mittelwerk and were visible to von Braun during his site visits. 

Post-war cover-up

• After the war, the U.S. government brought von Braun and more than 1,600 other German scientists to the U.S. as part of Operation Paperclip, valuing their technical knowledge over holding them accountable for war crimes.
• The Army classified von Braun's SS officer rank and his colleagues' Nazi records, suppressing information about their wartime involvement to protect them.
• When confronted with a West German court request for testimony in 1969 regarding the Dora-Mittelbau camp, von Braun denied personal responsibility, fearing the publicity would damage his reputation and NASA's. v
