Various reference sources give his birth year as 1901: e.g. Bibliothèque nationale de France; Dictionnaire du cinéma français; sous la direction de Jean-Loup Passek. (Paris: Larousse, 1987); Ephraim Katz, The International Film Encyclopedia (London: Macmillan, 1980). On the other hand, the most detailed academic study of Batcheff's life and career, by Powrie & Rebillard, says that Batcheff was born on 22 or 23 June 1907 [p.2] and cites as evidence his marriage and death certificates [p.24]; in this case he would have started his appearances in film at the age of 16, and he would have been only 24 when he died.
