This volume brings together 14 classic papers by interpersonal pioneers. Collectively, these papers not only demonstrate the coherence and explanatory richness of interpersonal psychoanalysis, they anticipate the emphasis on relational patterns and analyst-analysand interaction that typifies much recent theorizing. Each paper receives a substantial introduction from a leading contemporary interpersonalist. The pioneers of interpersonal psychoanalysis are: H. Sullivan, F. Fromm-Reichmann, J. Rioch, C. Thompson, R. Crowley, E. Schachtel, E. Tauber, E. Fromm, H. Bone, E. Singer, D. Schecter, J. Barnett, S. Arieti, and J.Schimel.
