Book excerpt: In 1968, Wilfred Bion and Albert Mason emigrated to Los Angeles at the invitation of a group of young analysts to teach and train local clinicians in the British object relations tradition. They were joined by Susanna Isaacs Elmhirst for a period. London Kleinians in Los Angeles is a colorful account of the early days of psychoanalysis in LA, punctuated by in-person presentations from the leading Kleinians of the day, including Hanna Segal, Herbert Rosenfeld, Donald Meltzer, and Wilfred Bion himself. Their unpublished lectures from the 1960s and 1970s appear in Part I. Part II features seminal papers by the founding fathers of the Psychoanalytic Center of California (PCC): James Gooch, James Grotstein, Arthur Malin, and Albert Mason, the group's leading spokesperson. PCC continues to function as a vital center of psychoanalytic training and education in the British object relations tradition. The unearthing of four unpublished contributions from four founding Kleinians is an incredible find for psychoanalysis and this book is highly recommended to all professionals and trainees in the field. Those with an interest in the history of psychoanalysis will find much to excite them.
