HOW SCIENCE RUNS – IMPRESSIONS FROM A SCIENTIFIC CAREER. BY ERIC J.
MITTEMEIJER
Reviewed by Mike Glazer
"In another section, the author has some criticism about the famous
Rietveld method in powder diffraction. He points out that the original
idea for this method was put forward by Bert O. Loopstra, who later
discussed the idea of whole-pattern fitting with Bob van Laar. In order
to create a computer program to carry out the method, they hired the
computer-savvy Hugo M. Rietveld. The first paper by Loopstra and
Rietveld was published in _Acta Crystallographica_ in 1969, having been
submitted in 1968. A later paper published in 1969 by Rietveld alone in
_Journal of Applied Crystallography_ is the one that is always quoted
and led to the name 'Rietveld method' or 'Rietveld refinement'.
Mittemeijer points out that this did grave injustice to the originator
of the method, Bert Loopstra. Rietveld later left science to become a
librarian: Mittemeijer says the notion that he left science because he
was disappointed that the method had not found wide acceptance at the
time is just a 'fairy tale'. Thus, according to the author, the profile
refinement method should more justly be called the 'Loopstra method',
concluding that this story has a sad ending."

Where did they find the text of the judgement ? Any verdict somewhere ?
Condamned by "impressions" !
Any text from Loopstra who had a lot of time to tell something but
never do it ?

Mittemeijer is not the only author who disputes the "fame" of Hugo
Rietveld. There is a publication of Henk Schenk about the exact same
topic. In those days it was a scandal at ECN,
