A Note on the History of the IAG
The International Association of Geodesy can trace its roots back to the early 19th century, a time of great progress in geodesy, when Bessel and Gauss made important contributions to the science. One of Bessel's pupils was J.J. Baeyer, who later became an officer of the Prussian General Staff. In 1861 General Baeyer wrote a report suggesting that the states of Europe should work together on the measurement of the size and shape of the earth and proposing methods to achieve this aim. The King of Prussia accepted the report and invited the countries concerned to subscribe to the plan.
