Abstract. 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.

IUGG的发展（1940–2000）

摘要。第二次世界大战后，国际大地测量与地球物理学联合会（IUGG）有了新的治理和成员结构，重新开始。战争期间开发的技术在国际地球物理年（1957-1958年）的非凡全球科学努力中得到应用。地缘政治格局的重大变化带来了IUGG结构的进一步变化。涵盖多个学科的国际科学运动变得司空见惯，国际科学机构被组织和联网。在此期间（1940年至1999年），分别在不同的国际场所举行了15次会员大会和2次非常会员大会。介绍了每个大会的摘要，以及IUGG的结构，财务，成员，和出版物。还介绍了领导联盟并为联盟发展做出贡献的科学家。
