The establishment of the Ewald Prize, for outstanding contributions to the science of crystallography, was announced in February 1986 and was given wide publicity. The name of the Prize was chosen with the kind consent of the late Paul Peter Ewald, to recognise Professor Ewald's significant contributions to the foundations of crystallography and to the founding of the International Union of Crystallography, especially his services as the President of the Provisional International Crystallographic Committee from 1946 to 1948, as the first Editor of the IUCr's publication Acta Crystallographica from 1948 to 1959, and as the President of the IUCr from 1960 to 1963.
Shortly after the death of Professor Ewald, his family informed the President that Professor Ewald had wished to make a bequest to the IUCr. After consulting Mrs Ewald, this generous bequest, together with a donation from the Ewald family and a donation from the IUCr, was used as starting capital for the Ewald Prize. The interest from this capital and further donations from the IUCr are used to finance the Prize.
The Prize consists of a medal, a certificate and a financial award. It is presented once every three years during the triennial International Congresses of Crystallography. The thirteenth Ewald Prize will be presented at the Melbourne Congress in August 2023.

W.A. Hendrickson awarded the 13th Ewald Prize
The 13th Ewald Prize has been awarded to Wayne A. Hendrickson (Columbia University, NY, USA) for his exceptional contribution to structural biology including the development of MAD/SAD methods and crystallographic theory. No-one else is so singularly and formatively identified with the explosive growth in biological crystallography and the consequent benefits to chemistry and biology.
Wayne Hendrickson transformed structural biology when he discovered and perfected resonant diffraction methods for determining the atomic-level structures of biological molecules, namely the methods of MAD (multiwavelength anomalous diffraction) and its single-wavelength variation SAD, which are now “household” terms in the field of crystallography. MAD and SAD derive from a marriage of chemistry with physics and biology and are the methods of choice for de novo X-ray determinations where there is no structural precedent. The ease with which macromolecular structures are determined by these methods served in founding the field of structural genomics, and has led to a flood of atomic-level molecular hypotheses, including many from Hendrickson himself, to inform biochemistry, physiology and genomics.Like the late Professor Ewald, Hendrickson advanced the foundations of crystallography; his essential contributions include not only MAD and SAD but also his phase-encoding coefficients (Hendrickson–Lattman coefficients) and stereochemically restrained refinement.
Professor Hendrickson will deliver the Ewald Prize Lecture during the Opening Ceremony of the 26th IUCr Congress on 22 August 2023.

O. Kennard awarded the twelfth Ewald Prize
The twelfth Ewald Prize has been awarded to Dr Olga Kennard (Cambridge, UK) for her invaluable pioneering contribution to the development of crystallographic databases, in particular the Cambridge Structural Database (CSD), which as she early foresaw, has led "… to the discovery of new knowledge which transcends the results of individual experiment". Her own surveys using the CSD were fundamental in the development of crystal engineering, and are outstanding examples of the use of crystallographic databases as an essential tool for analysis and prediction. As founder of the CSD, director of the Cambridge Crystallographic Data Centre (CCDC) over decades, and being involved in the founding of the Protein Data Bank (PDB), Olga Kennard has made a fundamental impact on the development of modern crystallography.

T. Blundell awarded the eleventh Ewald PrizeThe eleventh Ewald Prize has been awarded to Professor Sir Tom Blundell (Department of Biochemistry, University of Cambridge, UK) for his work as one of the worldwide leaders in crystallographic innovation, especially at the interface with life sciences; starting with his work on determining the structure of insulin with Dorothy Hodgkin, he determined an exceptionally broad array of medically critical human protein structures, championing methods enabling drug design and discovery through structural optimization, crystallographic fragment screening, and computational modelling, and for being a leader in advanced crystallographic education internationally.

J.M. Cowley and A.F. Moodie awarded the first Ewald Prize
In 1987 it was announced that the first Ewald Prize had been awarded to Professor J.M. Cowley (Tempe, Arizona, USA) and Dr A.F. Moodie (Clayton, Victoria, Australia) for their outstanding achievements in electron diffraction and microscopy. They carried out pioneering work on the dynamical scattering of electrons and the direct imaging of crystal structures and structure defects by high-resolution electron microscopy. The physical optics approach used by Cowley and Moodie takes into account many hundreds of scattered beams, and represents a far-reaching extension of the dynamical theory for X-rays, first developed by P.P. Ewald.
