Bion was an original and influential psychoanalyst who led the equally-influential Tavistock Clinic. Klein gave him a training analysis. Bion once sat next to Ross at a dinner. Bowlby and Winnicott were Tavistock colleagues, Bowlby having worked alongside Bion on wartime officer selection. Lacan met him on a study-visit to England, and was influenced by his work. Beckett went to Bion while depressed and suffering from panic-attacks, but doubted that the treatment did him much good (other than being impressed by a lecture of Jung’s that Bion took him to).
