and became a psychiatry professor at Burghölzli, the same university hospital at which he completed his residency. He was also appointed director of the mental asylum in Rheinau. He served as the director from the years 1898 to 1927. While working at this asylum, Bleuler cared for long-term psychiatric patients. He also implemented both psychoanalytic treatment and research, and was influenced by Sigmund Freud.
During his time as the director of psychiatry at Burghölzli, Bleuler made great contributions to the field of psychiatry and psychology that made him known today. Given these findings, Bleuler has been described as one of the most influential Swiss psychiatrists.

used word association tests to integrate Freud's theory of repression with empirical psychological findings. As a series of letters demonstrates, Bleuler performed a self-analysis with Freud, beginning in 1905. Bleuler laid the foundation for a less fatalistic view of course and outcome of psychotic disorders along with C.G. Jung, who further used Bleuler's theory of ambivalence and association experiments to diagnose neurotic illnesses.
Bleurer found Freud's movement to be overly dogmatic and resigned from the

since 1907. He revised and expanded his schizophrenia concept in his seminal study of 1911, ''Dementia Praecox, oder Gruppe der Schizophrenien'' (''Dementia Praecox, or Group of Schizophrenias''). This was translated into English in 1950 (by Joseph Zinkin).
Bleuler distinguished between positive and negative symptoms of schizophrenia. Positive symptoms include symptoms not found in unaffected people. These may include hallucinations or delusions. Negative symptoms describe the absence of typical experiences such as social withdrawal or lack of pleasure. Bleuler also distinguished between basic and accessory symptoms as well as primary and secondary symptoms. Basic symptoms are those that are present in every case of schizophrenia, whereas accessory symptoms are those that may or may not occur depending on the patient. Bleuler defined primary symptoms as those that are directly related to neurobiological processes. Secondary symptoms, he said, are behavioral reactions to primary symptoms. The ability to differentiate these symptoms contributed to an increased understanding of schizophrenia in general.
Like Kraepelin, Bleuler argued that dementia praecox, or "the schizophrenias", was a physical disease process characterized by exacerbations and remissions. He argued that no one was ever completely "cured" of schizophrenia; there was always some sort of lasting cognitive weakness or defect that was manifest in behavior. Unlike Kraepelin, Bleuler believed that the overall prognosis was not uniformly grim. He believed "dementia" was a secondary symptom not directly caused by the underlying biological process. There were three other "fundamental symptoms" that included deficits in associations, affectivity, and ambivalence. He believed the biological disease was much more prevalent in the population due to its "simple" and "latent" forms.
Bleuler's changes to Kraepelin's dementia praecox were accepted by countries such as Switzerland and Britain. However, some countries, such as Germany, did not accept these changes at first. Bleuler's concept of schizophrenia was pushed aside due to its similarities to Kraepelin's dementia praecox. It was only widely accepted after Kraeplin's disease classification did not have direct evidence nor was it directly expressed in his patients.
In 1911, Bleuler wrote, "When the disease process flares up, it is more correct, in my view, to talk in terms of deteriorating attacks, rather than its recurrence. Of course the term recurrence is more comforting to a patient and his relatives than the notion of progressively deteriorating attacks". The

of persons diagnosed with (and viewed as predisposed to) schizophrenia was advocated by Bleuler.
He argued that racial deterioration would result from the propagation of "mental and physical cripples" In his ''Textbook of Psychiatry'', Bleuler states,

In 1917, Bleuler discussed the heredity involved in schizophrenia after psychiatrist Ernst Rudin published his findings. Bleuler agreed with Rudin in that having a family member with schizophrenia increases an individual's chance of also having the disease. However, Bleuler also found that Rudin's study did not use sufficient sampling methods, which threatened the integrity of the study. While looking further into the heredity of schizophrenia, Bleuler made several conclusions that differed from Rudin's. One conclusion Bleuler made was that the schizophrenic gene was not a dominant trait. He also concluded that the disease involves a dihybrid, complex gene and does not include a monohybrid gene. Bleuler also said that there may be a polymorphic aspect to schizophrenia, meaning it presents itself in different forms.
Bleuler found that in order for schizophrenia to present itself in patients, several elements must come together. He found that there are a wide variety of symptoms associated with schizophrenia that can lead to a potential diagnosis. Bleuler concluded that several aspects of the disease are not genetically inherited. These tend to be behavioral aspects and positive symptoms, including hallucinations, delusions, and strange ideas.
He believed the disease's central characteristics were the product of splitting between the emotional and the intellectual functions of the personality. He favored early discharge from hospital into a community environment to avoid

, pondered on the origins of the sense of guilt, and studied the process of what he termed ''switching'' (the affective shift from love to hate, for example).
Bleuler was known for his clinical observation and willingness to let symptoms speak for themselves. He was also known for his skillful expository writings. Bleuler has never been credited with healing his patients. Like Sigmund Freud he experimented on patients in his care; many were sterilised and many committed suicide.[L. L. Hvens/S. N. Ghaemi, ''Psychiatric Movements'' (2004) p. 334 and p. 353.]
Later in his life, Bleuler studied and published works on psychoids. Within these works, he proposed that social, mental, and physical aspects of life are not separate from each other. Instead, he argued, they are seen as aspects of a sole life principle. These ideas were not particularly popular among the scientific community and did not receive a great deal of attention.
