Jonas Cohn

Born in Görlitz on December 2, 1869, into a Jewish family, he studied in Leipzig, Heidelberg, and Berlin and first earned a doctorate in botany before turning fully toward philosophy, psychology, and pedagogy. He worked in Wilhelm Wundt’s pioneering psychology laboratory in Leipzig and later qualified at Freiburg, where he built a long academic career.

He became known as a representative of Southwest German Neo-Kantianism and wrote on logic, aesthetics, ethics, psychology, and education. Reference works describe him as a distinguished teacher of aesthetics, and later scholarship still treats his writing on aesthetic value as an important contribution to Neo-Kantian thought.

After 1933, as a Jewish scholar, he was driven out of academic life in Germany and emigrated to England. He died in Birmingham on January 12, 1947. His life links the worlds of philosophy and early experimental psychology, and his work reflects a steady effort to take conflicting ideas seriously rather than force them into easy agreement.
