A British Missionary by the name of John Batchelor (1854-1944) translated the Bible into the Ainu language during his sixty years spent with them (Refsing, 2000).
John Batchelor was convinced that the Ainu were of Aryan descent and through this his views have influenced many generations of Western linguists (Refsing, 2000).
