Fritz Joubert Duquesne

Frederick "Fritz" Joubert Duquesne was a South African Boer and German soldier, big-game hunter, journalist, and spy. Many of the claims Duquesne made about himself are in dispute; over his lifetime he used multiple identities, reinvented his past at will, claimed family ties to aristocratic clans and famous people and even asserted the right to military titles and medals with no third-party verification.
