The 1920s was the decade when psychoanalysis moved from the fringes of accepted medical practice into the mainstream. It also witnessed the birth of the English-language International Journal of Psychoanalysis. Freud continued to dominate the psychoanalytic arena with his continuing innovations and expansion of ideas but topics of interest outside of his inspiration also grew. The influx of women into the profession led to new discussions on female sexuality and, possibly, to greater interest in psychoanalysing children. The papers in this volume deal with substantial issues in the development of psychoanalysis that still have profound echoes in psychoanalytic discussion today. Beautifully edited, with the papers divided into their subject matter and contextualised through comprehensive and clear introductions, this is an essential anthology of classic papers with contributions from Karl Abraham, Sandor Ferenczi, Anna Freud, Edward Glover, Karen Horney, Ernest Jones, Melanie Klein, Joan Rivière, and Hermine von Hug-Helmuth.
