The objective of this paper is to study the trajectories of the women who carried out research in the institutes of the Board for Advanced Studies (JAE) during the thirties. The JAE was a public institution that brought together the main centers dedicated to research in Spain and during three decades (1907-1939) it contributed in a remarkable way to the formation of the Spanish scholars.

Women acceded to these research centers throughout the thirties. In the months before the outbreak of the Spanish Civil War in July 1936, there were more than forty women carrying out research at the JAE, mostly at the National Institute of Physics and Chemistry and at the Center for Historical Studies, dedicated to research in humanities.

Women working in the JAE delimited a group highly qualified located in the space reserved for the training and selection of the future scholars. This paper aims to study what happened in the following years with this first generation of early researcher women. It tries to characterize their main trajectories and to evaluate, as far as possible, how many of these women followed each one of them. It is assumed that the main trajectories can be grouped into three large groups: those who followed their research career either in research institutions or in the universities, those who sought other professional positions as secondary school teachers or chemist owners, and those who abandoned their scholar careers because of marriage. Nevertheless, the consequences of the Spanish Civil War add a fourth group: those who suffered repression by the Franco regime, either because they fled into exile or because they were purged and expelled of their positions.
