Editing Claude Allègre (section)

===Scientific administration===
Allègre made many contributions to the organisation of the geological and geochemical sciences in France and Europe throughout his career. In 1981, he became the first president of the [[European Union of Geosciences]] (EUG), which was established to coordinate a biennial scientific congress for geoscientists across Europe.<ref>{{cite web|url=https://www.egu.eu/about/historical-highlights/eug/|title=Historical highlights of the European Union of Geosciences (EUG)|last=Schlich|first=Roland|date=1 October 2003|access-date=6 January 2024}}</ref> The EUG later merged with the European Geophysical Union, to become the European Geosciences Union (EGU), in 2004. In 1988, 
Allègre created the [[European Association of Geochemistry]] and presided over an inaugural international conference on geochemistry in Paris. This led to the establishment of the annual 'Goldschmidt Conferences' of the international geochemistry community, in cooperation with the [[Geochemical Society]] which are held in alternate years in Europe, and in the United States.<ref name=DSA>{{cite journal|first=Albrecht W|last=Hofmann|title=

In 2004, Allègre was presented with the distinguished service award of the Geochemical Society for his 'enormous' service to the geochemical profession. In his citation, [[Albrecht Hofmann|Al Hofmann]] commented that Allègre's 'actions have not always been popular ... but they have always been guided by far-sighted strategic thinking and planning, and usually by deep insight.' He also characterised Allègre's approach to service as one that involved 'hatching a far-flung idea ... hand picking a few people ... and then letting them do the work.'<ref name=DSA/>
