On January 29, 1946, Alfred Balachowsky, a Buchenwald concentration camp internee, was called by French prosecutor M. Dubost regarding activities at the Buchenwald concentration camp. He testified that he was able to get a hold of the archives of Block 46 and was able to note all the experiments that were recorded in the archives. Block 46 was the infamous block for experiments where the internees were utilized as guinea pigs.
