The program committee is organizing a rich scientific program of microsymposia and keynote lectures to show the growing scientific leadership of the ECA Special Interest Groups and the transversal and networking activity of the General Interest Groups. At ECM27 there will be commemorations of the important centennial for Crystallography; the Max Theodor Felix von Laue, Walter Friedrich and Paul Knipping seminal experiments. The meeting will provide good opportunities to show the strength and leadership of European crystallography and its connection with society, all being the preamble of 2013 International Year of Crystallography. The award ceremonies for the European Crystallographic Association prizes, Max Perutz and Bertaut, will also take place at ECM27.
