Indeed, saying "back to that" with some disdain reveals your are the physicist interested by properties of already structurally known compounds.The crystallographer says "towards the posibility to solve the structure of unknowncompounds" and for that you need the structure factors. Then comes

I would be curious if the Royal Swedish Academy of Sciences has archivesconcerning this Gregori Aminoff 1995 Prize decision/investigation :http://www.cristal.org/rietv025/foto3.jpgWho was contacted as reference ? Was Loopstra contacted and if yes, any positive answer from him ?;-)envoyé : 18

Bonjour Alan,My problem with the Bob van Laar and Henk Schenk paper is that it would have beencredible if signed by van Laar alone or better by Loopstra and van Laar and also ifpublished before 1980 or 1990, not in 2018.That 2018 paper looks strongly as initiated by Henk Schenk and the main
My personal feelings are that regardless of the origin of the idea, Hugo did
the work that made crystallographic full pattern fitting possible. That
implementation was not just a “programming task” as the minimal capabilities of
computers of the day required significant innovation for memory

Dear Luca.
Since I administer the Rietveld mailing list, I could have changed the name
years ago when Van Laar and Schenk published their history, with which I
largely sympathise. I didn't, because everyone now calls it "Rietveld
Refinement", a name invented by Terry Sabine, who worked with
Given the involvement of Alan in the early days I would be confident to trust
his view.
So why we don't try to fix a bit the mistake. We could:
- start renaming this list as Loopstra-Rietveld list ;-) ( I would keep the
name Rietveld in hit, first who got the idea, second the programmer)

Pawley (1980) and even Rietveld only appeared as #14

It's a widespread phenomenon. What about America being named for Vespucii
