This paper gives a micro-sociological view on the methodology used by Else Frenkel-Brunswik in the famous study The Authoritarian Personality (Adorno et al. 1950). A thorough reconstruction of the theoretical and methodological concepts of Else Frenkel-Brunswik eventually allows for a full appreciation of her works from a today’s social research perspective, especially of her role in the field of authoritarianism-research. The paper deals with (i) Else Frenkel-Brunswik’s role in the research team of The Authoritarian Personality, (ii) the way she followed up on her earlier work, (iii) the question of in which ways her parts of the study were object of criticism by the numerous critics of TAP, and (iv) the ways she herself responded to these critics. The material basis for such an approach is the archival material available in the “Archive for the History of Sociology in Austria (AGSO)” in Graz, Austria, which holds parts of the estate of Else Frenkel-Brunswik, most of all her correspondence and unpublished typoscripts of later publications, as well as at the Institute for Jewish Research (YIVO) in New York, which holds the papers of the American Jewish Committee, i.e., draft reports, memoranda, and some interview protocols of the TAP study.
