フランス極東学院
Séraphin Couvreur (; EFEO Chinese transcription: kóu sái fēn; 14 January 1835 – 19 November 1919) was a French Jesuit missionary to China, sinologist, and creator of the EFEO Chinese transcription. The system devised by Couvreur of the École française d'Extrême-Orient was used in most of the French-speaking world to transliterate Chinese until the middle of the 20th century, after what it was gradually replaced by pinyin.
