These newly discovered clinical seminars of Wilfred Bion, which include supervisions, personal case presentations, and lectures on psychoanalytic theory, represent his initial foray into many years of work that have inspired South American analysts for nearly a half a century.The clinical and theoretical work of Bion arguably ranks rather high in the current psychoanalytic firmament-as national and international conferences convene regularly to continue discussing the contemporary relevance of his work. His work has served as a source of inspiration to contemporary psychoanalysts in all three regions of the International Psychoanalytical Assocation-Ronald Britton, Antonino Ferro, Giuseppe Civitarese, Thomas Ogden, James Grotstein, and Paolo Sandler, just to name a few. These newly discovered clinical seminars from work Bion conducted in Buenos Aires in 1968 help us to further fill out the picture of his versatile gifts. In these seminars, we find lectures on Bion’s elaborations on his epistemological research-still on-going in the 1960s when he went to Buenos Aires; a lecture on the Grid and its clinical relevance.
