This paper is based on a talk given at the conference to celebrate the Work of Hanna Segal and attempts to summarise her contribution to psychoanalysis. I suggest that in addition to being the important presenter of the work of Melanie Klein, she made major contributions to our understanding of many analytic ideas, for example, symbol formation, the usefulness of the concept of the death instinct and the relation between phantasy and reality. She was a pioneer in the analytic treatment of psychosis and sh wrote important papers on literature and aesthetics. She was a great teacher and emphasised the central role played by the analytic setting in representing the attitude of the analyst.
