[Rolf Hassler: from leucotomy to stereotaxy]. / Rolf Hassler: von der Leukotomie zur Stereotaxie.

Rolf Hassler is one of the most renowned German specialists in psychiatry, neurology and neuroanatomy. Hassler's career exemplifies medicine as scientific endeavor. Relaying on an expertise in neuroanatomy gained at Oscar and Cecile Vogt's Kaiser Wilhelm Institute, especially regarding the structure of the thalamus, Hassler enabled Freiburg University's neurosurgery clinic the invention of stereotactic "stepped leucotomy" and established thalamotomy internationally in a leading way. While directing the Neuroanatomical/Neurobiological department of the Max Planck Institute for Brain Research from 1959 until 1982, Hassler continued to study the effects of stimulation and targeted subcortical electrocoagulation in the cat brain. The Freiburg trained neurosurgeon Gert Dieckmann helped Hassler to apply the newly gained knowledge for the stereotactic therapy of torticollis, tics and obsessions and compulsions. The use however of thalamotomy also as a surgical therapy for aggressiveness in children, mainly during the late 1960s and early 1970s, is starting to provoke public criticism. Contrary however to the accusation of a medicine shaped by Nazi ideology into a "science without humanity", Hasslers career reveals a problematic intrinsic to medicine: the together of "art of healing and science".

Psychosurgery in the History of Stereotactic Functional Neurosurgery.

The paper invites to reappraise the role of psychosurgery for and within the development of functional stereotactic neurosurgery. It highlights the significant and long-lived role of stereotactic neurosurgery in the treatment of severe and chronic mental disorders. Stereotactic neurosurgery developed out of psychosurgery. It was leucotomy for psychiatric disorders and chronic pain that paved the way for stereotactic dorsomedial thalamotomy in these indications and subsequently for stereotactic surgery in epilepsy and movement disorders. Through the 1960s stereotactic psychosurgery continued to progress in silence. Due to the increased applications of stereotactic surgery in psychiatric indications, psychosurgery's renaissance was proclaimed in the early 1970s. At the same time, however, a public fearing mind control started to discredit all functional neurosurgery for mental disorders, including stereotactic procedures. In writing its own history, stereotactic neurosurgery's identity as a neuropsychiatric discipline became subsequently increasingly redefined as principally a sort of "surgical neurology," cut off from its psychiatric origin.

The introduction of leucotomy in Germany: National Socialism, émigrés, a divided Germany and the development of neurosurgery.

Thinking about the chronology of the introduction of leucotomy in Germany sheds new light on the hypothesis of a special 'radical' approach of German psychiatry to the treatment of the mentally ill during the period of National Socialism. Moreover, it offers new insights into the transnational and interdisciplinary conditions of the introduction of leucotomy in early divided post-war Germany.

The Origins of Human Functional Stereotaxis: A Reappraisal.

In order to shed light on the first application of human functional stereotactic neurosurgery, whether it was in the realm of movement disorders, as has been claimed repeatedly, or in the realm of psychiatry, a review of the original scholarly literature was conducted. Tracking and scrutinising original publications by Spiegel and Wycis, the pioneers of human stereotactic neurosurgery, it was found that its origin and the very incentive for its development and first clinical use were to avoid the side effects of frontal leucotomy. The first applications of functional stereotactic neurosurgery were in performing dorsomedial thalamotomies in psychiatric patients; it was only later that the stereotactic technique was applied in patients with chronic pain, movement disorders and epilepsy. Spiegel and Wycis' first functional stereotactic operations were for obsessive-compulsive disorder, schizophrenia, and other psychiatric conditions.

'Electroshock Therapy' in the Third Reich.

The history of 'electroshock therapy' (now known as electroconvulsive therapy (ECT)) in Europe in the Third Reich is still a neglected chapter in medical history. Since Thomas Szasz's 'From the Slaughterhouse to the Madhouse', prejudices have hindered a thorough historical analysis of the introduction and early application of electroshock therapy during the period of National Socialism and the Second World War. Contrary to the assumption of a 'dialectics of healing and killing', the introduction of electroshock therapy in the German Reich and occupied territories was neither especially swift nor radical. Electroshock therapy, much like the preceding 'shock therapies', insulin coma therapy and cardiazol convulsive therapy, contradicted the genetic dogma of schizophrenia, in which only one 'treatment' was permissible: primary prevention by sterilisation. However, industrial companies such as Siemens-Reiniger-Werke AG (SRW) embraced the new development in medical technology. Moreover, they knew how to use existing patents on the electrical anaesthesia used for slaughtering to maintain a leading position in the new electroshock therapy market. Only after the end of the official 'euthanasia' murder operation in August 1941, entitled T4, did the psychiatric elite begin to promote electroshock therapy as a modern 'unspecific' treatment in order to reframe psychiatry as an 'honorable' medical discipline. War-related shortages hindered even the then politically supported production of electroshock devices. Research into electroshock therapy remained minimal and was mainly concerned with internationally shared safety concerns regarding its clinical application. However, within the Third Reich, electroshock therapy was not only introduced in psychiatric hospitals, asylums, and in the Auschwitz concentration camp in order to get patients back to work, it was also modified for 'euthanasia' murder.

A Material History of Electroshock Therapy : Electroshock Technology in Europe until 1945.

The article considers the history of electroshock therapy as a history of medical technology, professional cooperation and business competition. A variation of a history from below is intended; though not from the patients' perspective (Porter, Theory Soc 14:175-198, 1985), but with a focus on electrodes, circuitry and patents. Such a 'material history' of electroshock therapy reveals that the technical make-up of electroshock devices and what they were used for was relative to the changing interests of physicians, industrial companies and mental health politics; it makes an intriguing case for the Social Construction of Technology theory (Bijker et al., The social construction of technological systems: new directions in the sociology and history of technology. MIT Press, Cambridge, MA, 1987).

'A Berlin psychiatrist with an American passport': Lothar Kalinowsky, electroconvulsive therapy and international exchange in the mid-twentieth century.

The emigration of Lothar Kalinowsky (1899-1992) might, at first glance, seem to be a history of coincidence and twists of fate, but it is shown to be a truly entangled and intertwined history and story. The international introduction of electroconvulsive therapy was not only closely involved with the political, scientific and economic conditions during World War II, but the story of Kalinowsky's relevance to it emerges from competing stories, told differently in Europe and the USA - and by Kalinowsky himself. Tracing these stories up to the end of the 1960s reveals Kalinowsky as an influential inheritor and patron of Berlin Biological Psychiatry, rather than telling the history of an émigré innovator of international neuropsychiatric research.

["Psychological employees" in psychiatry. The establishment of clinical psychology at the example of Lilo Süllwolds diagnostic efforts to incipient schizophrenia]. / "Psychologische Mitarbeit" in der Psychiatrie. Die Etablierung der Klinischen Psychologie am Beispiel von Lilo Süllwolds diagnostischen Bemühungen um die beginnende Schizophrenie.

Lilo Süllwold (*1930) was the first psychologist in the German Federal Republic to acquire habilitation for Clinical Psychology at a Medical Faculty. However, she had already been appointed professor for Clinical Psychology following to a new University Act implementing the recommendations of the National Council of Science and Humanities. Her habilitation treatise to justify the initial professorship appointment centered on a self-made questionnaire as a diagnostic tool for beginning schizophrenia. The manner how the questionnaire together with the politico-scientific structural changes at the German Federal universities endowed the young psychologist with a carrier in psychiatry, is an illuminating example of psychology's way into psychiatry: the institutionalization and professionalization of Clinical Psychology in psychiatry since the end of the 1950s up to the end of the 1970s. In a comparative perspective on the developments of Clinical Psychology in the German Democratic Republic, the example demonstrates not only the role of new psychological theories und methods in research and clinic in enabling the entry of the new profession into psychiatry, but also the importance of initial socio-economic and socio-politic frame conditions and decisions. The negotiation of the scope or limits of competences between doctors and psychologists created more than a professional niche inside the clinic; it changed psychiatry and psychology as academic branches in their structures due to the establishment of new Clinical Psychology departments. The role of the psychologist turned from a doctor's "assistant" into a colleague at "eye level".

"Early Psychosis" as a mirror of biologist controversies in post-war German, Anglo-Saxon, and Soviet Psychiatry.

The English term "early psychosis" was coined in the 1930s to refer to feelings of irritability, loss of concentration, hypochondriac ideas, moodiness, and lassitude that were seen to precede the onset of clear-cut hallucinations and delusions. The history of thinking about "early psychosis" under names such as "latent," "masked," "mild," "simple" or "sluggish" schizophrenia before World War II and afterwards on the different sides of the Wall and the Iron Curtain reveals "early psychosis" as a mirror of quite aged international biologist controversies that are still alive today and to the same extent as they are misunderstood, are influential in their implications in today's psychiatry.
