(1894 - 1975) German vice admiral, head of Foreign Affairs and Intelligence section of the German armed forces (Abwehr), the number two man to Wilhelm Canaris. An important 4pp. folio, partly-printed D.S. and 4pp. of notes entirely in his hand, written in the Mondorf prisoner-of-war-camp, June 5, 1945, a 'fragebogen', or 'Personnel Questionnaire' issued by the Allies and whose completion was required of all high-ranking military officers. Buerkner lists his biographical details, political organization memberships, writings, speeches, travel, income, promotions and so on. More importantly, he lists all of his travels, including several trips to a secret 'German general', and most closely follow what would later become targets of Nazi aggression. Interestingly, both of Buerkner's bosses were hanged: Canaris for his involvement in the bomb attempt on Hitler's life, and Alfred Jodl, following his conviction for war crimes. Very slightly worn at the margins, else very good and worthy of further research.
