- Hugo Rietveld
Hugo M. Rietveld is a Dutch crystallographer and one of the most prominent crystallographers of the 20th century. He is famous for his invention of the Rietveld refinement method, which is used for the characterisation of crystalline materials from powder diffraction data. The
Rietveld refinementuses a least squares approach to refine a theoretical line profile (calculated from a known or postulated crystal structure) until it matches the measured profile. The introduction of this technique was a significant step forward in the diffraction analysis of powder samples.
[http://home.planet.nl/~rietv025/ Hugo M. Rietveld] was born in
The Hague, The Netherlands, on 7 March 1932. After completing Grammar School he went to Australiaand studied physics at the University of Western Australiain Perth.
1964he obtained his PhD degree with a thesis entitled "The Structure of p-Diphenylbenzene and Other Compounds", a single crystal neutronand X-ray diffractionstudy. This investigation was the first single crystal neutron diffractionstudy in Australiaand was conducted at the nuclear reactor, HIFAR, in Sydney.
In 1964 he became a research officer at the
NetherlandsEnergy Research Foundation ECN at Petten, The Netherlands, and was mainly involved in neutron powder diffractionstudies of uranates and other ceramiccompounds.After a scientific and managerial career with ECN he retired in 1992.
The Royal Swedish Academy of Sciencesawarded Hugo M. Rietveld, the Aminoff prize in Stockholm, 31 March 1995.
