In 2024, in recognition of his services to the Polish Crystallographic Society and the Polish crystallographic community in general, the prize was awarded to Professor Marek Wołcyrz. The professor perfectly meets the criterion: “for outstanding achievements in the field of crystallography in order to support the scientific activity of scientists specializing in this discipline” because, among other things, for many years he was the main organizer of the annual Polish Crystallographic Meetings in Wrocław and the Chairman of the Crystallography Committee of the Polish Academy of Sciences and participated in the work of the committee for the organization of the National Crystallographic Olympiad. Thank you, Professor!
