French School of the Far East

The French School of the Far East (French: École Française d'Extrême-Orient, pronounced [ekɔl fʁɑ̃sɛːz dɛkstʁɛm ɔʁjɑ̃]), abbreviated EFEO, is an associated college of PSL University dedicated to the study of Asian societies. It was founded in 1900 with headquarters in Hanoi in what was then French Indochina. After the independence of Vietnam, its headquarters were transferred to Phnom Penh in 1957, and subsequently to Paris in 1975. Its main fields of research are archaeology, philology and the study of modern Asian societies. Since 1907, the EFEO has been in charge of conservation work at the archeological site of Angkor.

Paul Mus was a member of EFEO since 1927, and "returned to Hanoi in 1927 as a secretary and librarian with the Research Institute of the French School of the Far East until 1940."
