Mathematics without Borders: The Centennial of the International Mathematical Union

September 27-28 2021, Palais Universitaire, Strasbourg

The Centennial Conference

We celebrate the Centennial of the International Mathematical Union in Strasbourg, founded in 1920 at the ICM in the same location. The International Mathematical Union (IMU) was founded in 1920 at Strasbourg, marked by the peculiar situation after World War I. Today’s IMU was re-created after World War II. The centennial of the foundation is a moment to reflect on the long and varied history of international cooperation of mathematicians and show that the modern IMU seeks to include mathematicians from all countries.

The opening session were held under the High Patronage of Mr. Emmanuel Macron, President of the French Republic.

The International Mathematical Union (IMU)

The IMU is an international scientific organization, whose aim is to support and promote mathematics and mathematicians worldwide. It is a non-governmental and not-for-profit organization, representing approximately 90 member countries, and is a member of the International Science Council (ISC).

The IMU oversees and convenes the International Congress of Mathematicians (ICM) every four years. The inaugural ICM was held in Zurich in 1897. At the ICM, the IMU presents some of the most prestigious awards in mathematics – the Fields Medal, the Nevanlinna Prize/Abacus Medal, the Gauss Prize, the Chern Medal, and the Leelavati Award.

The centennial in Strasbourg

The IMU was officially established on 20 September 1920 in Strasbourg, just prior to the ICM in Strasbourg.
