International Union Of Crystallography
The International Union of Crystallography (IUCr) is an organisation devoted to the international promotion and coordination of the science of crystallography. The IUCr is a member of the International Council for Science (ICSU). Objectives The objectives of the IUCr are to promote international cooperation in crystallography and to contribute to all aspects of crystallography, to promote international publication of crystallographic research, to facilitate standardization of methods, units, nomenclatures and symbols, and to form a focus for the relations of crystallography to other sciences. The IUCr fulfils these objectives by publishing in print and electronically primary scientific journals through the ''Acta Crystallographica'' journal series, as well as '' Journal of Applied Crystallography'', '' Journal of Synchrotron Radiation'', '' IUCrJ'', the series of reference volumes ''International Tables for Crystallography'', distributing the quarterly ''IUCr Newsletter'', mai ...

Johannes Martin Bijvoet
Johannes Martin Bijvoet (23 January 1892, Amsterdam – 4 March 1980, Winterswijk) was a Dutch chemist and crystallographer at the van 't Hoff Laboratory at Utrecht University. He is famous for devising a method of establishing the absolute configuration of molecules. In 1946, he became member of the Royal Netherlands Academy of Arts and Sciences. The concept of tetrahedrally bound carbon in organic compounds stems back to the work by van 't Hoff and Le Bel in 1874. At this time, it was impossible to assign the absolute configuration of a molecule by means other than referring to the projection formula established by Fischer, who had used glyceraldehyde as the prototype and assigned randomly its absolute configuration. In 1949 Bijvoet outlined his principle, which relies on the anomalous dispersion of X-ray radiation. Instead of the normally observed elastic scattering of X-rays when they hit an atom, which generates a scattered wave of the same energy but with a shift in p ...

Ted Baker (chemist)
Edward Neill Baker (born 29 October 1942) is a New Zealand scientist specialising in protein purification and crystallization and bioinformatics. He is currently a distinguished professor at the University of Auckland.

André Authier
André — sometimes transliterated as Andre — is the French and Portuguese form of the name Andrew and is now also used in the English-speaking world. It used in France, Quebec, Canada and other French-speaking countries, as well in Portugal, Brazil and other Portuguese-speaking countries. It is a variation of the Greek name ''Andreas'', a short form of any of various compound names derived from ''andr-'' 'man, warrior'. The name is popular in Norway and Sweden.

Theo Hahn
Theo is a given name and a hypocorism. Greek origin Many names beginning with the root ''Theo-'' derive from the Ancient Greek word (), which means God, for example: *Feminine names: Thea, Theodora, Theodosia, Theophania, Theophano and Theoxena *Masculine names: Theodore, Theodoros/Theodorus, Theodosius, Theodotus, Theophanes, Theophilus, Theodoret and Theophylact Germanic origin Many other names beginning with "Theo-" do not necessarily derive from Greek, but rather the old Germanic "theud", meaning "people" or "folk". These names include: *Theobald, Theodahad, Theodard, Theodebert, Theodemir, and Theodoric People with the name Theo See Theo and Théo for a current alphabetical list of all people with the first name Theo or Théo in the English Wikipedia.
