Hi, I am too young and out of the mainstream of powder diffraction to know all the stories about the born of the Rietveld Method.
My question is: the article of Rietveld is published in 1969 and the article about the born of this method come out after that Hugo Rietveld pass away, why did this happen 49 years after?

Loopstra, van >Laar and Rietveld.". And more precisely : " HS wrote in Dutch: ‘Loopstra had the idea that it should be better to use the whole powder profile rather than estimated intensities to solve structures, van Laar worked it out mathematically and Rietveld programmed it." I conclude then : no idea for Rietveld and van Laar since they are from Loopstra; no mathematics for Rietveld and Loopstra; no programming for Loopstra and van Laar. A very clear result of the work of three individuals. The HS view... Seems that Rietveld had not the same opinion and claimed for ideas too and possibly for mathematics as well. Best, Armel
