Otto Gross was the first analyst to link his work with radical politics, connecting inner, personal transformation with outer, collective change. Since his death in 1920 his work has been suppressed, despite his seminal influence on the developing analytic discipline and on the fields of sociology, philosophy and literature. Here Gottfried M. Heuer introduces Gross life and ideas, using an innovative, historiographic methodology he terms trans-historical: a psychoanalytic, intersubjective, and trans-temporal approach to the past, aimed at healing wounded history in the present.
