When we talk about the Frankfurt School, names like Adorno, Horkheimer, and Marcuse usually grab the spotlight. But before these thinkers shaped critical theory as we know it, Carl Grünberg laid the foundation—both literally and intellectually.
Born in 1861 in Focsani (in what was then Austria-Hungary), Grünberg was a Marxist historian and economist. His work focused on the materialist conception of history, and he was deeply invested in understanding the relationship between economics, class structures, and social change.
The Institute’s First Director
Grünberg’s major claim to Frankfurt School fame is that he was the founding director of the Institute for Social Research, established in 1923 at Goethe University Frankfurt. Under his leadership, the Institute’s early work was squarely focused on Marxist economic analysis, historical materialism, and empirical research—a far cry from the more philosophical and cultural analyses that came later.
His tenure (1923–1929) was marked by a commitment to scientific socialism. Grünberg believed in a rigorous, evidence-based approach to Marxist theory, combining historical documentation with theoretical insight. In many ways, his vision was closer to what we’d now call political economy.
A Stepping Stone to Critical Theory
Grünberg’s leadership provided the institutional backbone that allowed the Frankfurt School to flourish later. After he stepped down due to ill health, Max Horkheimer took over in 1930 and gradually steered the Institute toward what we now recognise as Critical Theory—a blend of philosophy, sociology, psychology, and cultural critique.
Although Grünberg himself wasn’t a “critical theorist” in the Adorno-Horkheimer sense, his influence was vital. Without his work setting up the Institute and framing its early Marxist orientation, the Frankfurt School’s later breakthroughs might never have happened.
Why He Still Matters
Today, Carl Grünberg serves as a reminder of the Frankfurt School’s deep roots in Marxist economic theory. His commitment to rigorous scholarship and his belief in understanding society through material conditions remain key touchpoints for anyone exploring the full arc of Critical Theory’s development.
