The author offers a personal selection and discussion of some papers that epitomize the enduring relevance of Kurt R. Eissler’s (1908-1999) contributions to psychoanalytic therapy. The innovations of technique embodied by these works (on parameters, schizophrenia, adolescence, cure, fees, and the treatment of the dying patient) reveal a therapeutic approach that is a natural implementation of psychoanalytic science: patientcentered, maximally comprehensive, and appropriately flexible. Firsthand observations of Eissler’s clinical manner and a selected bibliography of clinical contributions are also presented.
