This is a new translation of the classic 1932 Dictionary by the author, for which Freud wrote a Preface praising the "precision and correctness" of the author's work and calling it a "fine achievement". The dictionary is not only an important source of information about psychoanalysis in Vienna in the 1930s but is also an insight into its author, as movingly attested by the 'Epilogue' to this edition written by his daughter Verena Sterba Michels, son-in-law Robert Michels, and grand-daughter Katherine J. Michels. This new edition also includes a transcript of an interview with the author by Dr William Langford, Chairman of the Department of Child Psychiatry at the Columbia College of Physicians and Surgeons.
