Academic Publishing in Poland During the First World War: A Study of Zygmunt Janiszewski's Case

This article is devoted to the study of the mathematical publications of Zygmunt Janiszewski (1888–1920), a major figure in Polish science at the beginning of the 20th century. Engaged in the Polish Legion between 1914 and 1920 in the struggle for national independence, Janiszewski was not only one of the founders of the Polish School of Mathematics, but alsothe initiator of the creation of the journal Fundamenta Mathematicae, the world’s first specialized scientific journal devoted exclusively to pure mathematics.The aim of this study is to reconstruct the conditions under which his works were published and to analyze the range of his organizational activities—particularly in the fields of academic teaching, Polish scientific societies, and scholarly publishing. Through this analysis, we highlight Janiszewski’s decisive role in the structuring and consolidation of the modern Polish mathematical community.
