Jeremiah Curtin (6 September 1835 - 14 December 1906) was an American ethnographer, folklorist, and translator. Curtin had an abiding interest in languages and was conversant with several. From 1883 to 1891 he was employed by the Bureau of American Ethnology as a field researcher documenting the customs and mythologies of various Native American tribes. In 1900, Curtin travelled to Siberia, which resulted in the book A Journey in Southern Siberia (published posthumously). The first part of the book is a travelogue; the last two-thirds is a record of the mythology of the Buryat people, including a prose summary of Gesar as performed by Manshuud Emegeev.
