Emigrated neuroscientists from Berlin to North America

Frontotemporal dementia: Past, present, and future

INTRODUCTION

The history of frontotemporal dementia (FTD) is both old and new. This study explores its historical roots, dating back to the 19th century, while recognizes it as a distinct neurological entity only a few decades ago.

METHODS

This qualitative study and literature review provides an overview of FTD's historical background, birth, evolution, and future directions.

RESULTS

Recognition of FTD was hindered by rigid perceptions of dementia, the division between neurology and psychiatry, reliance on IQ-based assessment, limited neuroimaging capabilities, and lack of pathological proof. Overcoming these barriers involved revisiting early pioneers' approaches, focusing on focal impairment, establishing non-Alzheimer's disease cohorts, fostering collaboration, and developing diagnostic criteria. Current gaps include the need for biology-oriented psychiatry education, biological biomarkers, and culturally sensitive, objective clinical instruments predicting underlying pathology.

DISCUSSION

Independent multidisciplinary centers are essential. The future of FTD lies in disease-modifying therapies, presenting new opportunities for healthcare professionals and researchers.

[A researcher and physician who gained international fame: Otfrid Foerster (1873-1941) as Nobel Prize candidate]

This paper discusses the 17 Nobel Prize nominations for the neurologist and neurosurgeon Otfrid Foerster (1873-1941). Drawing on files from the Stockholm Nobel Prize Archive, primary and secondary literature, it addresses the following questions: what were the reasons given by nominators for Foerster's nominations? What was the relationship between him and his nominators? Why was he ultimately not awarded the Nobel Prize? Most nominators of Foerster's highlighted as the main motive his Handbuch der Neurologie, which he had edited with Oswald Bumke. According to the nominators, this book together with Foerster's neurosurgical work had an enormous impact on contemporary neurology. Furthermore, his "honorable character" was underlined in the nomination letters; however, these reasons were not sufficient for the Nobel Committee: the members classified the handbook as not being original research. Despite this, Foerster's fame is reflected in the present, for example in the Otfrid Foerster Medal, which has been awarded to researchers by the German Society of Neurosurgery since 1953.

History of cerebral localization and the emigration plight of three neuroscience giants from Nazi Germany: Josef Gerstmann, Adolf Wallenberg, and Franz Josef Kallmann

The Nazi regime held power for well over a decade in Germany and were steadfast in their anti-Semitic agenda. Among the massive cohort of immigrants to America were approximately 5056 Jewish physicians, including several highly esteemed neurologists and neuroscientists of the time. Emigrating to a new world proved difficult and provided new challenges by way of language barriers, roadblocks in medical careers, and problems integrating into an alien system of medical training and clinical practice. In this article, the authors examine the tumultuous and accomplished lives of three Jewish German and Austrian neurologists and neuroscientists during the time of the Third Reich who shaped the foundations of neuroanatomy and neuropsychology: Josef Gerstmann, Adolf Wallenberg, and Franz Josef Kallmann. The authors first examine the successful careers of these individuals in Germany and Austria prior to the Third Reich, followed by their journeys to and lives in the United States, to demonstrate the challenges an émigré physician faces for career opportunities and a chance at a new life. This account culminates in a description of these scientists’ eponymous syndromes.

Although their stories are a testimony to the struggles in Nazi Germany, there are intriguing and notable differences in their ages, ideologies, and religious beliefs, which highlight a spectrum of unique circumstances that impacted their success in the United States. Furthermore, in this account the authors bring to light the original syndromic descriptions: Gerstmann discovered contralateral agraphia and acalculia, right-left confusion, and finger agnosia in patients with dominant angular gyrus damage; Wallenberg described a constellation of symptoms in a patient with stenosis of the posterior inferior cerebellar artery; and Kallmann identified an association between hypogonadotropic hypogonadism and anosmia based on family studies. The article also highlights the unresolved confusions and international controversies about these syndromic descriptions. Still, these unique cerebral syndromes continue to fascinate neurologists and neurosurgeons across the world, from residents in training to practicing clinicians and neuroscientists alike.

[Fredy Quadfasel (1902-1981) : Neuropsychiatrist, politically persecuted NS opponent and his impact in American exile]

The physician and psychologist Dr. Fredy Quadfasel, born in East Prussia, was trained in neuropsychiatry by Kurt Goldstein in Frankfurt/Main and by Karl Bonhoeffer at the Charité in Berlin. After he was detained by the Gestapo due to political opposition, he was probably denounced for offending the so-called Malicious Practices Act (Heimtückegesetz) from March 1933, and imprisoned for 2-3 months. In 1934/35 he emigrated to the USA via England and Canada, where he initially ran a neuropsychiatry office in New York. Very soon he was able to take on an academic post and became an instructor in neurology. After medical military service in 1944-1947 at the Cushing General Hospital in Framingham near Boston, he was appointed head of the neurological department. Later he moved on to the Boston Veterans Administration Hospital. His academic positions included being an instructor in neurology at Harvard Medical School and associate professor at the Boston University School of Medicine. He had a considerable impact on neurology, especially on the locally emerging discipline of neuropsychology represented by Harold Goodglass and Norman Geschwind. Despite a lack of personal records of Quadfasel, a chequered reconstruction of his life and work was possible due to many archival documents with which it was possible to trace the career of a highly esteemed neurologist in Germany and the USA.

[German neurology and neurologists during the Third Reich: Preconditions and general framework before and after 1933]

This article focuses on the institutional development of neurology in Germany up to the rise to power of the National Socialists and the radical sociopolitical changes after 1933. A wide range of scattered secondary literature was assessed and evaluated. Additionally, some original sources are literally quoted and interpreted according to the context. Since the end of the nineteenth century a complicated process of separation from internal medicine and psychiatry led to the formation of a self-conscious discipline of neurology. The first generation of German neurologists succeeded in founding the German Journal for Neurology ("Deutsche Zeitschrift für Nervenheilkunde") in 1890 and their own neurological association, the Society of German Neurologists ("Gesellschaft Deutscher Nervenärzte", GDN) in 1907. On an international scale, however, the institutional implementation of neurology with only a small number of chairs and few neurology departments remained more than modest. The ambitions for autonomy ended 2 years after the change of power in 1933. Regulatory interventions by the government and psychiatric interests led to the fusion of the GDN with the psychiatric specialist society, the new association being called the Society of German Neurologists and Psychiatrists ("Gesellschaft Deutscher Neurologen und Psychiater", GDNP) in 1935. In this group psychiatrists dominated the discourse. The expulsion, imprisonment and murder of physicians declared as non-Aryan or Jewish along with the forced consolidation ("Gleichschaltung") at the universities prompted profound changes in medical and academic life. It remains an ongoing challenge of neurological historical research to measure the impact of this upheaval on the few neurology departments in hospitals and private practices.

Learning soft skills the hard way: Historiographical considerations on the cultural adjustment process of German-speaking émigré neuroscientists in Canada, 1933 to 1963

This article is a historiographical exploration of the special forms of knowledge generation and knowledge transmission that occur along local cultural boundaries in the modern neurosciences. Following the inauguration of the so-called "Law on the Re-Establishment of a Professional Civil Service" in Nazi Germany on April 7, 1933, hundreds of Jewish and oppositional neurologists, neuropathologists, and psychiatrists were forced out of their academic positions, having to leave their home countries and local knowledge economies and traditions for Canada and the United States. A closer analysis of their living and working conditions will create an understanding of some of the elements and factors that determined the international forced migration waves of physicians and clinical neuroscientists in the twentieth century from a historiographical perspective. While I am particularly looking here at new case examples regarding the forced migration during the National Socialist period in Germany, the analysis follows German-speaking émigré neurologists and psychiatrists who found refuge and settled in Canada. These individuals form an understudied group of refugee medical professionals, despite the fact that the subsegments of refugee neurologists and clinical psychoanalysts in the United States, for example, have been a fairly well-investigated population, as the works of Grob (1983), Lunbeck (1995), or Ash and Soellner (1996) have shown. This article is primarily an exploration of the adjustment and acculturation processes of several highly versatile and well-rounded German-speaking physicians, who had received their prior education in neurology, psychiatry, and basic brain research. They were forced out of their academic home institutions and had to leave their clinical research fields as well as their disciplinary self-understanding behind on the other side of the Atlantic.
