Which person, in 1900, published a book called, "The Interpretation of Dreams" ?

In late 1899 (Review), with the publication date post-dated to 1900, the Austrian neurologist Sigmund Freud released a book that would fundamentally change the course of psychology. This work, "The Interpretation of Dreams," introduced his revolutionary theory of the unconscious mind. Freud, who considered it his most significant work, argued that dreams were not random nonsense but rather the "royal road to a knowledge of the unconscious activities of the mind." He proposed that dreams provide a window into our deepest, often repressed, thoughts and desires.

Freud's central theory was that all dreams represent a form of "wish fulfillment." He made a distinction between the "manifest content" of a dream, which is the storyline you remember, and the "latent content," its hidden, symbolic meaning. According to Freud, the mind uses a process of censorship to disguise unacceptable wishes as the often bizarre narratives we experience in sleep. By analyzing these disguised symbols, he believed it was possible to uncover unresolved conflicts and gain crucial insights into a person's psyche.

Unusually for a scientific text, the book is deeply personal, with Freud using many of his own dreams as case studies to illustrate his theories. Despite its eventual impact, the book was not an immediate success. The initial print run of 600 copies took eight years to sell, and it was largely ignored by the scientific community at first. However, as Freud's other work gained recognition, the book's popularity grew, and it went on to become one of the most important texts of the 20th century.
