The article aims to present the multidimensional activity of Ignacy Koschembahr-Łyskowski as a professor of Roman law and a member of the Codification Commission of the Republic of Poland. Based on archival sources, the course of his professional career is presented in a synthetic overview. An analysis of his scientific achievements shows the fundamental methodological assumptions relating to his perception of the role of Roman law at the outset of the 20th century. His views on the mutual relationships between Roman law and ABGB are also presented. Considerable attention is given to his participation in the work of the Codification Commission of the Republic of Poland and its reception. The discussion also addresses ‘the basic concept of the law of obligations’ and the draft of the general provisions of civil law authored by this scholar. The subsequent fate of the drafts prepared by Koschembahr-Łyskowski is also indicated.
