Since January 2011, the Secretariat of the International Mathematical Union is permanently based in Berlin, Germany. Under the supervision of the IMU Executive Committee, the Secretariat runs IMU’s day-to-day business and provides support for many IMU operations, including administrative assistance for the International Commission on Mathematical Instruction (ICMI) and the Commission for Developing Countries (CDC). The IMU Secretariat also hosts the IMU archive.
The Secretary General is responsible for conducting the ordinary business of the Union and for keeping its records.
For the first time in its almost 100-year history, IMU has a permanent secretariat. In the past, IMU conducted its business at the institution of the IMU Secretary General which usually also served as the legal domicile of IMU. At the General Assembly 2010 in Bangalore, India, the Weierstrass Institute in Berlin, Germany (WIAS) was elected as the host institution of the permanent secretariat. The operation of the secretariat is supported by grants from the German Federal Ministry of Education and Research (BMBF) and the State of Berlin.
The International Mathematical Union is grateful to the institutions that have hosted the IMU office in previous years. Beginning in 1950 with the preparations for the (second) foundation of IMU in 1951/1952 the IMU secretariat has operated in the following locations:
