Abstract A few years ago, the International Year of Chemistry (2011) was celebrated throughout the world with the organization of thematic conferences and symposia, special activities for children, the publication of a myriad of articles and reviews, and, of course, the release of postage stamps by many countries. Likewise, the International Year of the Periodic Table (IYPT) presents now another rare opportunity to relate the history of chemistry and showcase its societal benefits to a worldwide audience. As originally proclaimed by the United Nations and UNESCO, the IYPT also offers an incentive to promote international cooperation in the basic sciences for sustainable development and science education.
