The evidence describing von Braun and Haber's crimes is in a chapter called: "Pathways to Human Experimentation, 1933-1945: Germany, Japan, and the United States" in a Journal called Osiris.

A full biography of von Braun can be found here. It describes in detail his Nazi past, his relationship with Haber and a number of other Nazis, and then his escape from post-war prosecution into the arms of the US army. It also goes into detail about his role in the Disney family and his particular knack for selling his ideas, something that was of particular interest to the marketing efforts at Disney.

Walt's ignominious sexist, racist, anti-labor, right-wing, authoritarian past is described in detail in Walt Disney: Hollywood's Dark Prince. There are a number of references of how Walt's conservative ideas about the family, the role of women and of minorities transcends all the way down to the present movies and how his conservative views are carried on in the Disney studios today, well after his death.

Are these enough facts for you? Or do you not read books?
