This study is an attempt to shed light onto Henri H. Stahl’s contribution to the sociological monographs that were the core of the Bucharest School of Sociology’s activity. Stahl is presented as an active member of the School, bringing into it his own background and abilities, distinct or shared views, values and interests and then impacting it through his actions which, combined with other factors, distinctively change and shape its development. As such, the study is also not an attempt to summarize his theoretical developments and to compare and place them in rapport with those of other social scientists. The purpose of this study is to expose at least partially the degree to which the knowledge that Stahl generates and uses differs in shape and contents from that of Dimitrie Gusti, regarding the manner in which it is used in his course towards a certain role and status in the School, the manner in which his course in the School develops, and the manner in which his personal characteristics and options, group and organizational developments and the wider social context interact in order to shape published sociological knowledge.
Keywords: Henri H. Stahl, sociological monographs, Bucharest School of Sociology, knowledge.
