Abstract

Social Sciences and especially Sociology and History are very useful to understand how the Cryptographic Field has been shaped in France in 19th and 20th centuries. This paper tackles this issue explaining how and why this Field has been influenced in-depth by a strong process of ‘Professionalism’ under the Ecole Polytechnique rule.

    The first French Military Attachés (to Embassies) appeared in fact after 1826 thanks to the 1826 ordonnance that allowed (chap. II, art. 14, al. 2, see Journal militaire officiel, 2e semestre 1826, n° 16, p. 609) the French General Staff to appoint Officers to Embassies. The first were sent to Madrid and to Constantinople.

  16. 16.

    This 2nd Bureau was different from that one created at the end of the 1860 s in the Dépôt de la Guerre. One of the major difference was that the new one was part of a General Staff that did not exist before 1870.

  18. 18.

    The main part of the 2nd Bureau archives remained and are today in SHD (7 N 653–677). The archives of the « section de statistique » were partly destroyed, partly disseminated after the Dreyfus Affair. One can find some hints and traces of them in the « police spéciale » archives (Archives nationales, F7) and in the archives of the Préfecture de Police.
