Bonjour Armel. In answer to your question "Where did they find the text of the judgement ?" please see: "The development of powder profile refinement at the Reactor Centre Netherlands at Petten" Bob van Laar and Henk Schenk https://scripts.iucr.org/cgi-bin/paper?ib5058
Van Laar worked at Petten with Rietveld, and Schenk was the IUCr president. This paper is apparently the basis of Mittemeijer's book. His point is that scientific discoveries are often the result of the work of many people, yet we tend to simplify the process and attribute them to individual heros. Mike Glazer is simply reviewing his book.
