[2] Early in his medical career, he worked at the Clinic of Internal Medicine under Ladislav Syllaba, and at the Institute for the Mentally Ill under Antonín Heveroch.
After World War II, Vondráček became the "legendary head physician" at the Psychiatric Clinic and retired in 1957 after 25 years of service.
[5] Vondráček was a charismatic figure of the medical faculty, described as being a tall man with a beard, known for his dry humor.
His earliest books and articles date to 1923 and cover a wide range of issues, including psychiatric, psychological, sexological, pharmacology, and internal medicine, incorporating findings and observations of his time.
People with mental disorders often believe that they can predict the future or read minds, that they're cursed or vice versa 'chosen', that they come from another planet or another time.
According to Vondráček, tales about haunted castles, evil creations or living dead were created as a result of hallucinations and suggestions.
The memoirs show both his phenomenal memory and illustrate his life story, and additionally, they describe the first half of the 20th century with many interesting facts and details.
