Abstract. The International Union of Geodesy and Geophysics (IUGG) was established in 1919 to promote activities of already-existing international scientific societies dealing with geodesy, terrestrial magnetism and electricity, meteorology, physical oceanography, seismology, and volcanology. At the first General Assembly a Section of scientific hydrology was added, making a total of seven Sections of the Union. This paper introduces IUGG by presenting its current mission, structure, partners, and programs; discussing various international geophysical efforts before its origin; and describing the Union's development from the end of World War I to the beginning of World War II. During this period (1919–1939), the number of member countries increased from the 9 founding Member countries to 35; seven General Assemblies were held, each in a different international venue; and the number of delegates attending the assemblies increased from a few dozen to more than 800 scientists. At the Fifth General Assembly in 1933, the term “section” was replaced by “international association”. Each General Assembly of the Union, since the First General Assembly in Rome, Italy, in 1922 to the VII General Assembly in Washington, DC, USA, in 1939, is summarized, and the distinguished scientists who contributed to the Union's formation and it early development are introduced.

IUGG：开始，建立和早期发展（1919年至1939年）

摘要。国际大地测量与地球物理学联合会（IUGG）成立于1919年，旨在促进已经存在的有关大地测量，地磁和电，气象学，物理海洋学，地震学和火山学的国际科学学会的活动。在第一届大会上，增加了一个科学水文学科，使国际电联共有七个科。本文通过介绍IUGG当前的任务，结构，合作伙伴和计划来介绍IUGG。在起源之前讨论各种国际地球物理努力；并描述了从第一次世界大战结束到第二次世界大战开始期间联盟的发展。在此期间（1919年至1939年），成员国的数量从9个创始成员国增加到35个；举行了七届会员大会 每个都在不同的国际场所；参加会议的代表人数从几十人增加到800多人。在1933年的第五届大会上，“部门”一词被“国际协会”代替。总结了自1922年在意大利罗马举行的第一届大会到1939年在美国华盛顿举行的第七届大会以来的每届国际电联大会，并为电联的成立及其早期做出了贡献的杰出科学家开发介绍。
