Abstract
The International Association of Geodesy (IAG) is a constituent Association of the International Union of Geodesy and Geophysics (IUGG) since 1922, and the successor organization of the Mitteleuropäische Gradmessung. Its activities have changed dramatically from its beginning in 1862 till today. While it started with the aim of determining the regional anomalies of the Earth's curvature in Europe by connecting astronomical observatories through triangulation networks, it concentrates now on the observation and modelling of the phenomena and effects of physical processes in the System Earth employing mainly space techniques. The structural and scientific developments over time are summarised, and the present structure and activities are described in detail.
