IUGG evolves (1940-2000)

The International Union of Geodesy and Geophysics (IUGG) began anew after World War II with a new governance and membership structure. The technologies developed during the war were brought to bear in the extraordinary global scientific effort that was the International Geophysical Year (1957–1958). Major changes in the geopolitical landscape have brought about further changes in IUGG's structure. International scientific campaigns encompassing multiple disciplines became commonplace, and international scientific bodies were organized and networked. During this time period (1940–1999), 15 general assemblies and 2 extraordinary general assemblies were held, each in a different international venue. Summaries of each general assembly are presented, as well as overviews of the changes in IUGG's structure, finances, membership, and publications. The scientists, who led the Union and contributed to the development of the Union, are also presented.
