Stanley Cobb founded the Harvard Departments of Neurology (1925) and Psychiatry (1934) with Rockefeller Foundation funding. Cobb was an important transitional figure in both neurology and psychiatry. He and his friend Alan Gregg were the most visible parts of the Rockefeller Foundation psychiatry project, which prepared American psychiatry for the rapid growth of psychiatric research after World War II. Edward Shorter called him the founder of American biological psychiatry, but this misunderstands Cobb and the Hegelian evolution of twentieth-century American psychiatry. I review the major role of the Rockefeller Foundation in the evolution of American academic psychiatry and the disappearance of Cobb's teaching and that of his mentor Adolf Meyer, a founding father of American academic psychiatry.
