This publication is an analysis of the book by P.V. Morozov, R.A. Becker, Yu.V. Bykov, dedicated to the four most significant persons, who had an invaluable influence on psychiatry in the XX century (Emil Kraepelin, Eugen Bleuler, Sigmund Freud, Karl Jaspers). Among the advantages of the book on the history of psychiatry, one can stress out a successful extrapolation of the ideas of the “titans” to the current state of psychiatric science and a discussion of their work with the use of the actual language of current clinical psychiatry. This makes it possible to recommend the book not only to experienced psychiatrists and researchers, but also to young specialists, as well as residents and students. Another important achievement of the book is the successful disclosure of not only ideas, but also biographies of the “titans” placed in the scientific, historical, political, cultural and personal contexts.
