In 1906, he was appointed an Associate Professor at Charles University. In 1908, he established and led the Institute for Epileptics in Prague-Libeň. Heveroch was the head of the psychiatric department of a garrison hospital in Prague; in 1915, he was privy to a secret resistance organization, but in August 1917, he was sent to the Russian front. At the beginning of the 20th century, doctors in the field of psychiatry and neurology wanted to form their own organization. The Purkyn Association for the Study of the Mind and Nervous System formed on October 18, 1919; its first chairman was Heveroch. In the same year, he became the director of the Prague Insane Asylum. He obtained full professorship in 1921. He was a member of the Czechoslovak Academy of Sciences and Arts, Academy of Labour and the State Medical Board. He was also Vice President of the Society of the National Theatre. Heveroch was associated with the Psychiatric Clinic in Prague, but never became its leader; instead he left in 1904, and in 1924, established a second psychiatric hospital, which closed three years after he died. He also studied psychology and psychiatry of everyday life and tirelessly popularized psychiatry among laymen. His name thus became famous enough to become popular as a synonym for a psychiatrist.; and so, people used to say, "we'll call Heveroch on you", similarly as they later used the names of Mysliveček or Vondráček for the same purpose. "Pinel is said to be the one who removed the shackles from the mentally ill, Heveroch has opened the prison of psychiatry and let it get outside of the walls." In his medical research, he frequently applied the therapeutic principles of psychotherapy, but he did not use hypnosis and harshly rejected Freud'spsychoanalysis. However, he acknowledged the existence of the subconscious. From a philosophical point of view he was close to vitalism. He refused psychophysical parallelism. His direct pupils were Vladimír Vondráček and Otakar Janota. He himself was a pupil of Josef Thomayer. Vondráček described him as a respectable man, gentle, sober, with a focus on mathematics and philosophy, with a sense of humor, as an excellent speaker, trainer, organizer and debater. "He was extremely tidy. He was a man "adjusted to the vertical", which means that the pens on his desk were carefully and vertically sorted He walked quickly, often with his hands folded on his back, with his head tilted to the side." In more than 100 original works and articles, he devoted himself to various topics: aphasia and agnosia, the awareness of our own existence, the rhythm of life and its defects, the intuition, loss of awareness of our feelings, the self-reference and causality, the obsession, delusions, hallucinations, faint states, the soul of a crowd, "children pathologically lying", the restless children, and crime associated with school children, among other things. His book Diagnostika chorob duševních became the basic textbook of the Czechoslovak psychiatry, together with the book Psychiatrie by Kuffner. His essay O podivínech a lidech nápadných vividly depicts portraits of patients suffering from psychopathy or personality disorder. This book allegedly inspired Jaroslav Hašek when writing his Schweik. His work is pioneering and many of his ideas are still valid today. For example, in the six-part series called O poruchách jáství, he was the first in Bohemia to cover the phenomenon of depersonalization.
