In a post earlier today, I reported the sad news of the passing of Nuremberg prosecutor Whitney Harris. I went back to the proceedings of the trial to track down his participation. The full 42 volumes are available in pdf.
Whitney Harrris presented the Kaltenbruner case on 2-3 January 1946 (see Vol. 4, p. 288-311). In the final days of the trial, he cross examined two of the Gestapo witnesses, Karl Rudolf Werner Best and Karl Heinz Hofi'mann (Vol. 20, pp. 141-154, 182), and presented a few additional exhibits (Vol. 20, pp. 262, 562, Vol. 21, p. 300).
