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.

"[5] In his medical research, he frequently applied the therapeutic principles of psychotherapy (psychagogic, persuasion), but he did not use hypnosis and harshly rejected Freud's psychoanalysis.

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.

His essay O podivínech a lidech nápadných[7] (On Freaks and Striking People, 1901) vividly depicts portraits of patients (from today's perspective) who had psychopathy or personality disorder.

This book allegedly inspired Jaroslav Hašek when writing his Švejk, Heveroch's name is mentioned several times in the novel.

For example, in the six-part series called O poruchách jáství (On the Disorders of the Self, 1910), he was the first in Bohemia to cover the phenomenon of depersonalization (although he didn't use this designation).

He is buried at the Vinohrady Cemetery in Prague; his grave is decorated with his bust made by his friend, the sculptor Jaroslav Horejc (1886–1983).
