  Ziehen (1862-1950) was an extraordinarily versatile scholar. He is regarded as a great psychiatrist, psychologist and philosopher, as well as one of the founding fathers of child psychiatry. He began work on developmental psychiatry in Jena, publishing his first article "Association Psychology in Childhood" in 1898. He worked in close collaboration with the educators Rein and Trüper. In 1902 the first part of his book "Mental Diseases in Childhood" was published, followed by further publications in 1904 and 1906. These volumes are regarded as the second most important in child psychiatry in Germany. His work is the first systematic and almost complete compendium in this field. Ziehen introduced the medical terms "affective psychosis" and "psychopathic constitution" to psychiatric literature. He also worked in the fields of medical education and education.
