Jerzy Jedlicki was one of the most prominent Polish historians, whose activity extended to more spheres of intellectual and public life. His works dealing, for instance, with Polish intelligentsia in the nineteenth century, have importantly contributed to Polish historiography and intellectual life. The pro memoria note focuses on Jedlicki as a lecturer, a historian with a widely-recognised output, and a political commentator. Although of expressly leftist views, Jedlicki remained open-minded for other ideological views and interpretations.
