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 Rietveld when he was Australian. Rietveld himself simply called it "Profile Refinement".
For similar reasons, the country Colombo is now known as Amerigo, while Columbo is a famous TV detective. Concerning the code, many, including the first versions of GSAS (and FullProf?) were based on the original Rietveld code that I modified <https://citeseerx.ist.psu.edu/document?repid=rep1&type=pdf&doi=b17a97ce3721d11695f24f9710e74ba61eb880a0> at Harwell in 1972 and distributed at ILL. Armel, when he writes of his inspiration during long nights at ILL collecting data <http://www.cristal.org/iniref/lbm-story/> (on my instrument D1A), probably had a version directly from Rietveld, though neither the code, nor D1A, nor anything between Rietveld (1967,1969) and Le Bail (1987) are referenced. Van Laar and Schenk have a brief history of how the code developed in those "missing" 20 years https://journals.iucr.org/a/issues/2018/02/00/ib5058/ Regards Alan ________________________________ Dr Alan Hewat, NeutronOptics Grenoble, FRANCE (from phone) alan.he...@neutronoptics.com +33.476984168 VAT:FR79499450856 http://NeutronOptics.com/hewat _______________________________ On Thu, 17 Aug 2023, 19:21 Luca Lutterotti, <luca.luttero...@unitn.it> wrote: > 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.
