French Crystallographic Association
The French Crystallographic Association (AFC) brings together physicists, chemists and biologists that use crystals and crystallography in their research or develop new crystallographic methods. Originally part of the French Society of Mineralogy, the AFC was founded in 1953 by Hubert Curien and André Guinier. Today, its main goals are to promote dissemination of knowledge and exchange between French speaking crystallographers from all fields, and in particular to organize or support specialized or interdisciplinary workshops and conferences, educational actions and training courses in the area of crystallography. During the biannual AFC conferences, the AFC awards three PhD prizes in each of its research areas: Physics, Chemistry and Biology. Claude Sauter, scientist at thInstitut de Biologie Moléculaire et Cellulairein Strasbourg is the President of the AFC from January 1st, 2022.

Crystallography
Crystallography is the experimental science of determining the arrangement of atoms in crystalline solids. Crystallography is a fundamental subject in the fields of materials science and solid-state physics (condensed matter physics). The word "crystallography" is derived from the Greek word κρύσταλλος (''krystallos'') "clear ice, rock-crystal", with its meaning extending to all solids with some degree of transparency, and γράφειν (''graphein'') "to write". In July 2012, the United Nations recognised the importance of the science of crystallography by proclaiming that 2014 would be the International Year of Crystallography. denote a direction vector (in real space). * Coordinates in ''angle brackets'' or ''chevrons'' such as <100> denote a ''family'' of directions which are related by symmetry operations.

Hubert Curien
Hubert Curien (30 October 1924 – 6 February 2005) was a French physicist and a key figure in European science politics, as the President of CERN Council (1994–1996), the first chairman of the European Space Agency (ESA) (1981–1984), and second President of the Academia Europæa and a President of Fondation de France. Biography Born in Cornimont, Vosges in Lorraine, Curien enlisted in the French resistance during World War II. After the war he studied physics at the École normale supérieure in Paris. Curien became the director general of the Centre National de la Recherche Scientifique (CNRS) in 1969, and was one of the founders of the European Science Foundation and chairman from 1979 to 1984. He was also head of the French space agency from 1976 to 1984, and first chairman of the board of ESA from 1981 to 1984. Curien was the Minister of Research of France from 1984 to 1986 and from 1988 to 1993. He entered the French Academy of Sciences in 1994. Curien was the Pre ...

André Guinier
André Guinier (1 August 1911 – 3 July 2000) was a French physicist who did important work in the field of X-ray diffraction and solid-state physics. He worked at the Conservatoire National des Arts et Métiers, then taught at the University of Paris and later at the University of Paris-Sud in Orsay, where he co-founded the Laboratory of Solid State Physics. He was elected to the French Academy of Sciences in 1971 and won the Gregori Aminoff Prize in 1985. In the field of small-angle scattering he discovered the relationship of particle size to intensity which is called Guinier's Law. He developed the Guinier camera for use in X-ray diffraction and contributed to the development of the electron microprobe by Raimond Castaing. Together with Prof George Dawson Preston he also gives his name to the Guinier-Preston zone Publications *Guinier, André (1955) ''Small-angle scattering of X-rays''.

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'', main ...

Scientific Organizations Established In 1953
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek ma ...
