There is a museum in the south east coastal town of Nha Trang dedicated to the lift and work of Alexandre Emile Jean Yersin.
Here is an extract from the Wikipedia entry for Monsieur Yersin:
Alexandre Yersin is well remembered in Vietnam, where he was affectionately called Ông Năm (Mr. Nam/Fifth) by the people. Following the country's independence, streets named in his honor kept their designation, and his tomb in Suoi Dau was graced by a pagoda where rites are performed in his worship. Yersin's house in Nha Trang is now the Yersin Museum, and the epitaph on his tombstone describes him as a "Benefactor and humanist, venerated by the Vietnamese people". At Ha Noi, a French Lycée has his name. A private university founded in 2004 in Da Lat was named "Yersin University" in his honour.
