The interwar period in Vienna was a remarkably fertile era, brimming with diverse schools of thought and influential figures who left an indelible mark on the twentieth century. Among these luminaries, Helene Bauer stands out as a hidden gem. A close collaborator of Hans Kelsen, Max Adler, Otto Bauer, and Otto Neurath, she also proved to be a formidable critic of Ludwig von Mises, Friedrich Hayek, and Joseph Schumpeter. Helene Bauer in Vienna brings her work back into the spotlight, revisiting the debates on political economy from that epoch-debates that resonate profoundly with the challenges of our own time.
