Frédéric Joliot-Curie
Several French national institutions settled on the plateau after the end of World War II. The CNRS is the first to settle there, headed by Frédéric Joliot-Curie, who bought the estate Button at Gif-sur-Yvette in 1946. The following year, the newly created CEA (the High Commissioner is also Joliot-Curie) to purchase land. The same year, ONERA settles on the plateau in Palaiseau. The Saclay center was inaugurated in 1952.
