Paris-Sud University



Paris-Sud University (French: Université Paris-Sud), also known as the University of Paris — XI (or as the Université d'Orsay before 1971), was a French research university distributed among several campuses in the southern suburbs of Paris, including Orsay, Cachan, Châtenay-Malabry, Sceaux, and Kremlin-Bicêtre campuses. In 2020, the university was replaced by the Paris-Saclay University.

On 16 January 2019, Alain Sarfati was elected President of the Université Paris-Sud. He succeeded Sylvie Retailleau, who was elected as President of ComUE Université Paris-Saclay.

History
Paris-Sud was originally part of the University of Paris, which was subsequently split into several universities. After World War II, the rapid growth of nuclear physics and chemistry meant that research needed more and more powerful accelerators, which required large areas. The University of Paris, the École normale supérieure and the Collège de France looked for space in the south of Paris near Orsay. Later some of the teaching activity of the Faculty of Sciences in Paris was transferred to Orsay in 1956 at the request of Irène Joliot-Curie and Frédéric Joliot-Curie. The rapid increase of students led to the independence of the Orsay Center on 1 March 1965 (sometimes called "Université d'Orsay" thereafter). The institution became the "University of Paris-Sud (Paris XI)" in 1971.

Paris-Sud hosted a great number of laboratories on its large (236 ha) campus. Many of the top French laboratories were among them especially in particle physics, nuclear physics, astrophysics, atomic physics and molecular physics, condensed matter physics, theoretical physics, electronics, nanoscience and nanotechnology. University of Paris-Sud comprised some 104 research units.

Pierre-Gilles de Gennes and Albert Fert, two Nobel Prize winners of physics, were affiliated to the University of Paris-Sud. A number of the most renowned French mathematicians were affiliated with the University of Paris-Sud as well. Among them are the Fields medalists Pierre Deligne, Laurent Lafforgue, Jean-Christophe Yoccoz, Wendelin Werner and Ngô Bảo Châu.

Paris-Sud also comprised biology and chemistry laboratories, engineering and technology schools and had established partnerships with many of the surrounding technology centres and Grandes Ecoles. It also included Schools of Law, Economics and Management.

In 2020, University Paris–Sud was replaced by the University of Paris-Saclay.
