A 110-year history of the Swiss Neurological Society (SNG) through the biosketches of its first 42 presidents

The Swiss Neurological Society (SNG) was founded in 1908. In the 1930s, a pre- and postgraduate neurological curriculum and the recognition of neurology as medical specialty followed. In the 1950–1960s, first independent university departments were created in the country. On the occasion of the 110th anniversary of the SNG, the biosketches of its first 42 presidents (including C. von Monakow, R. Bing, M. Minkowski, H. Krayenbühl and M. Mumenthaler) are presented. The multidisciplinary and international influences that contributed to the development of neurology in Switzerland are discussed in the context of the national and international scientific, medical and political history.


Introduction
The Swiss Neurological Society (SNG) was founded on 15 November 1908 in Olten and constituted officially on 13 March 1909 in Bern at the presence of 64 of the 108 enrolled members. 1,2The committee was composed of the following 10 people: Robert Bing, Paul Dubois, Paul-Louis Ladame, Constantin von Monakow, Louis Schnyder, Schumann, Alfred Ulrich, Otto Veraguth, Emil Villiger and Gustav Wolff.
The main aims presented in the first by-laws were (1) the promotion of neurological research in collaboration with other medical fields (anatomy, physiology, medicine, surgery, psychology, psychiatry), (2) the support of interactions between members and (3) the representation of practical interests of neurology (e.g. in the care of patients and in teaching the discipline).
The initiative was taken, according to Charles Dubois and Minkowski by Bing, 1,2 according to Monakow's memoires by Paul Dubois and himself. 3It was certainly encouraged by the recent foundation of the national societies of the United States (1875), Belgium (1896), Germany (1907)  and Italy (1907). 4The birth of a new society (and discipline) in Switzerland was opposed by some internists (e.g.H. Sahli in Bern and L. Michaud in Lausanne) and psychiatrists (e.g. A. Forel in Zurich), but also supported by others (O.Naegeli and E. Bleuer in Zurich).As a consequence, it was only after decades that a pre-and postgraduate neurological curriculum, the recognition as medical specialty and the creation of independent departments were achieved.
The first 100 years of the SNG were summarized in the 2008 anniversary book. 5Ten years later, on the occasion of the 110th anniversary of the society, we now present the biosketches of its first 42 presidents.The main aim is herewith to revisit the multidisciplinary and international roots and influences contributing to the development of the SNG in the context of the scientific, medical and political history of Switzerland and Europe.Beyond this, it is our wish with this article to acknowledge the work and commitment of the SNG presidents, and all those who assisted them, in making neurology what it is today in our country.
von Monakow was born and grew up until the age of 10 in Wologda (North Russia), before moving first to Germany and at the age of 13 to Zurich, where he studied medicine (an article on C. von Monakow authored by C. Jagella can be found in this same issue of CTN).After graduation, he worked at the Heilanstalt St Pirminsberg (SG), where he performed first experimental and clinicopathological studies.He obtained the 'venia docendi' from the University of Zurich in 1885.The same year, he returned to Zurich to start a private practice.In 1886, he opened a private experimental laboratory, and in 1887 (with two assistants) an outpatient clinic (ambulatorium).Only in 1913, the University Hospital officialized this institution offering the salary of one resident and new rooms in the Haus Belmont (Figure 1(b)).In 1894, after he declined the chair of neuropsychiatry in Innsbruck, he was offered the first chair of neurology in Switzerland with the title of 'Extraordinarius ad personam' ('fu ¨r hirnanatomische Fa ¨cher und Nervenpoliklinik'), a position he would hold for 29 years.His research focus was experi-mental neuropathology; his international reputation was, however, also linked to his monumental books 'Gehirnpathologie' (1897) and 'Die Lokalisation im Grosshirn' (1914).In the latter, he coined the term 'diaschisis' (which he had presented already in lectures since 1902) to describe functional dysfunctions distant from brain lesions and recovery of function over time. 6In 1917, he founded the Swiss Archives of Neurology and Psychiatry (SANP) in which he served as editor-in-chief for 13 years.The SANP remained the official journal of the SNG (in the first years, the publication organ of the SNG had changed several times and included the 'Correspondenzblatt fu ¨r Schweizer Aerzte' and the 'Neurologische Zentralblatt') until 2015.
During his presidency, a first meeting of the SNG was held in Bern at the presence of 64 of the 104 members of the society and inaugurated by two lectures by E. Clapare `de and C. von Monakow.The 2nd and 3rd meetings were held in Zurich and Geneva, respectively.The 4th meeting was organized in Basel with an emphasis of the developing field of neurosurgery.
Dubois grew up in La Chaux-de-Fonds and Geneva (where he became a friend of J. Dejrine from the age of 12).He studied medicine in Bern, where he trained with the internists B. Naunyn, H. I. Quincke and L. Lichtheim.In 1876, he first opened a private practice, later with other colleagues a private clinic (in the Villa Bel-Air and then Hospital Victoria) in Bern.He obtained the 'venia docendi' from the University of Bern in 1888.In 1902, he became Extraordinarius 'ad personam' for neuropathology.His research was focused first on 'medical electrology', with studies on diagnostic and treatment applications.In 1902 (with L. Schnyder), he organized an International Congress on this topic in Bern.After this event, his long-standing interests in psychotherapy (noteworthy, Dubois had no psychiatric training and never worked in a psychiatric institution), which at that time was dominated by hypnotism and psychoanalysis, became his main research focus.Influenced by the works of S. Weir-Mitchell and H. Bernheim, he developed, with his pupil L. Schnyder, a 'third' psychotherapeutic school.This was based on the dialogue with the patients (the so-called 'rational or persuasive method') aiming at 'educating' them and leading them to altruistic thoughts (as antidote to self-centred concerns). 12He coined the term 'psychoneurosis', and his motto was 'Sie mu ¨ssen an ihre Heilung glauben' ('you must believe in your cure').His reputation was international and he treated patients coming from all over Europe (including M. Proust).His major work 'Les psychonévroses et leur traitement moral (1904)' was translated into eight languages.He maintained over the years very close contacts with J. Dejerine and his wife A. Klumpke who frequently met him in Bern. 13Noteworthy, he maintained throughout his life a very critical position towards S. Freud and psychoanalysis. 12uring his presidency, Dubois (assisted by L. Schnyder) and the SNG board engaged in the preparations of a Second International Congress of Neurology, Psychiatry and Psychology (a first meeting had taken place in 1907 in Amsterdam), which had to be cancelled because of the outbreak of the First World War, which also interrupted all SNG activities for 2 years. 2 An obituary was written by L. Schnyder, 14 a biography by C. Mu ¨ller. 3 Paul-Louis Ladame (1842-1919), President 1916-1919  Ladame grew up in Neucha ˆtel (see Figure 3).He studied medicine in Zurich, Wu ¨rzburg, Bern and Paris.After gaining experience in different hospitals (Neucha ˆtel, La Chaux-de-Fonds, Vienna), he worked first for 12 years as general practitioner in Le Locle.Subsequently, he founded and directed a home for orphans in Dombresson.In 1884, he spent a few months in Paris (J.M. Charcot, F. Raymond and E. Brissaud) and Berlin (K.Westphal) to enhance his neurological expertise.After his return, he worked in a private practice in Geneva seeing neurological and psychiatric patients, performing research on hypnosis, medico-legal and forensic topics (with a focus on moral and social questions) and teaching at the Faculties of Medicine and Law.He obtained the 'venia docendi' from the University of Geneva in 1888, but to his great regret -and despite his international reputation -no hospital/ academic position was offered to him.15 During his presidency, the SNG first met with the Swiss Psychiatric Society (at that time still named 'Societé des Médecins-aliénistes suisse'), the president of which was his son Charles Ladame (who later became Ordinarius of psychiatry at the University of Geneva). 1 Both gave speeches in which the importance of the links between neurology and psychiatry were stressed.2 At the 1916 meeting in Bern, the SNG board decided to give birth to the SANP as official organ of the society.The 13th SNG meeting was held in Lucerne and dedicated to War Neurology.At the banquet of that meeting, Ladame gave a vibrant, patriotic speech in which he warned against 'foul compromizes'.In the last SNG meeting of his presidency, the announcement was made that J. Dejerine had left 8000 Swiss francs to support Swiss neurological research (in French).
An obituary was written by F. Naville, 16 a thesis on him by D. Pazeller-Piguet.An obituary was written by Haymaker, who stressed his encyclopedic knowledge of the literature and his overall 'stellar position in the neurologic world'. 19Others reported on his life and oeuvre. 20,21 Otto Veraguth (1870-1944), President 1922-1924  Veraguth grew up in Chur (see Figure 5).He studied medicine in Zurich, where he trained with C. von Monakow (he was his first assistant).He visited Paris (J.M. Charcot, E. Brissaud, J. Babinski, J. Dejerine) and London, where he worked 6 months with V. Horsley and developed an interest in neurosurgery, which he maintained for his entire career.In 1897, he opened a private praxis in Zurich, but continued to work with von Monakow and in Paris on research projects on the pathology and physiology of the nervous system, including those on the psychogalvanic reflex (a seminal contribution which was published in 1908 and was source of a scientific controversy with C. J. Jung).22 Veraguth obtained the 'venia docendi' from the University of Zurich in 1900.During the First World War, he worked with Brunnschweiler (and during some time also with Long) in a military hospital in Lucerne.In 1918, he was appointed associate professor of physical therapy in Zurich, where he much promoted sport and physiotherapy in medicine.He was among the first worldwide to report the successful removal of an intramedullary spinal tumour (in 1910) and lumbar disk herniation (in 1927), which were performed with (Veraguth remained surgically active for years after graduation) H. Brun, a surgeon from Lucerne.23 Veraguth's name is linked also to the suggestion of a fold of the upper lid as typical sign of depression.24 Honorary presidents of the SNG receive the 'Veraguth's medal'.
6][27] During his presidency, the 70th anniversary of Monakow was celebrated and accompanied by a special issue ('Festschrift') of the SANP in his honour with contributions by authors such as W. M. Bechterew (Saint Petersburg), S. Ramon y Cajal (Madrid), E. Flatau (Warsaw), S. Goldflam (Warsaw), K. Goldstein (Frankfurt am Main), H. Head (London), G. G. J. Rademacher (Utrecht),  O. Marburg (Vienna), P. Marie and H. Bouttier (Paris), G. Mingazzini (Rome) and I. P. Pawlow (Saint Petersburg). 1,28On this occasion, von Monakow gave a memorable lecture with the title 'Fifty years Neurology', which ended with the proud words 'Wir wissen und wir werden wissen' ('we know and we will know'). 2 thesis on Veraguth was written by P. Su ¨ssli, 22 in which the great variety of his scientific and clinical interests and his aristocratic manners were emphasized.During his presidency, the SNG meetings were devoted to the cerebellum (1924), psychotherapy (1925) and basal ganglia (1925).Schnyder was the first president of the SNG to die while in duty (Ladame had retired prematurely, just few months before his death).
An obituary was written by C. Dubois, 29 in which he underlined Schnyder's friendship with his father, as well as his great (also humanistic) erudition and kind personality ('d'une noble simplicité' and 'au doux sourire').
Part II -The time before and during World War II 7. Edouard Long (1868-1929), President 1927-1929  Long grew up in Geneva (see Figure 7).He studied medicine in Geneva and Paris.He trained in Paris with J. Dejerine and A. Dejerine-Klumpke, from whom he derived his research focus in clinico-pathological correlation studies (e.g. on sensory pathways and syphilis of the spinal cord).He obtained the 'venia docendi' from the University of Geneva in 1900 while still working for most of his time with the Dejerine's in Paris.During the First World War, he was active with his wife in Bourg-en-Bresse in a military hospital, and visited a similar institution headed by Veraguth in Lucerne.In 1919, he was appointed Extraordinarius of neuropathology at the University of Geneva.He had affiliation with the Department of Internal Medicine (chaired first by L. Bard, from 1920 by M. Roch), where he was active as clinical consultant (and later 'médecin adjoint') in neuropsychiatry.He was supported in his clinical and research activities by his wife, Mrs Long-Landry from Paris. 2 During his presidency, the SNG meeting (1928) was devoted to the pathology and therapy of the hypophyseal gland.In 2018, the SNG was approached by the American Neurological Association with the request of organizing (as planned in 1914) an international meeting in Switzerland, this time however devoted only to neurology.E. Long, R. Bing and C. Dubois were selected by the SNG board to serve in the organization of that meeting.Shortly thereafter, Long passed away, the second SNG president to die while in duty.
An obituary was written by F. Naville. 30 Francois Naville (1883-1968), President 1930-1933 Naville grew up in Geneva (see Figure 8).He studied medicine in Geneva and Paris and trained in Paris with J.   31 He wrote a report (and subsequently a book) in which he presented the elements indicating the responsibility of the Soviet Union.This led first to an international political pressure and then criticism (also by the Red Cross and within his own country) which he resisted with great integrity and courage.
Only after several years the truth was officially recognized (in 1989 also in Russia) and Naville 'fully rehabilitated'.
During his presidency, the SNG board engaged again (a first attempt was made in 1911-1912, see above) to promote pre-and postgraduate teaching in neurology.The initiative, launched by M. Minkowski, was this time successful: in 1932, the Swiss Medical Association (FMH) recognized neurology as an independent specialty and in 1935 neurology became mandatory in the curriculum of medical students in Switzerland.The highlight of his presidency was the First International Neurological Meeting which took place -under the presidency of B. Sachs from New York -in Bern from 31 August until 4 September in Bern and was opened by the Vice President of Switzerland, G. Motta. 18In 1930, the SNG had 144 members.
An obituary was written by F. Martin and in the Revue Neurologique.An obituary was written in the Revue Neurologique 34 and by M. Minkwoski, 35 in which his role in the Swiss psychoanalytic society, the development of a neurobiologically and psychoanalytically based theory of neuroses, and some controversial aspects concerning his activity as expert in the assessment of patients with post-traumatic 'neuroses' are discussed.A memorable "confrontation" on this topic between Brun and de Morsier at the SNG meeting 1941 is mentoned also by Ott 41 .
Brunnschweiler grew up in Thurgau and studied medicine in Zurich.He trained in Zurich (with C. von Monakow), Paris (P.Marie, J. Dejerine, J. Babinski) and Berlin (H.Oppenheim).He worked during the First World War under Veraguth in Luzern in a military hospital.His research interest included the anatomy of the sensory pathways and clinical neurophysiology (with studies on galvanic reflex and chronaxie).In 1928, he obtained the 'venia docendi' from the University of Lausanne, where he had been working in a private practice since 1912.Brunnschweiler was a man of great culture and was married to a famous French pianist.
During his presidency, the first SNG meeting (1939) was devoted (as already in 1917) to War Neurology.The following year, the 50th Meeting of the SNG took place in Zurich.In 1943, the SNG had 143 members.
An obituary was written by Ott, who 30 years before had been convinced by Brunnschweiler to enter neurology, and of him he said: 'chez Brunnschweiler l'homme de science s'alliait au médicin dans le sense plus noble du terme'. 36 important contributions to clinical topics (including those on the aphasia of polyglots).
8][39] For 29 years (1931-1959), he was co-editor-in-chief of the SANP, in which he regularly published also on the history of the society and his protagonists.
The fact that Minkowski, who had been vice president of the SNG since 1936 and was elected president in 1943 as a Jew was seen at the time as a strong signal against anti-Semitic pressure from Germany.Minkowski later reported about this memorable moment and the emotions of honour and responsibility that overwhelmed him and led him to a solitary walk in the Bu ¨rgenstock mountain. 2uring his presidency, the SNG meetings took place with the Swiss Societies of Psychiatry (1943, Geneva) and Veterinary Medicine (1944, Langenthal).During the Second World War, Minkowski also actively served the army as a physician.
Obituaries were written by Mumenthaler and Akert 40 as well as his countryman Konorski, in which -his patriotism, modesty and unusual human qualities were emphasized.During his presidency, the SNG meetings were devoted to the use of streptomycin -which had been recently introduced in medicine -in neurology (Basel, 1947), the hypothalamus (Geneva, 1948) and traumatic brain injury (Bern, 1949).In Geneva, W. R. Hess, who would receive the following year the Nobel Prize for medicine, gave a main lecture on the role of the hypothalamus on the regulation of vegetative functions.
An obituary was written by Th.Ott, who said of him 'G.de Morsier fut pendant un quart de sie `cle, la personnalité dominante la plus active et la plus brillante, mais aussi la plus contestée de la Neurologie suisse'. 41.Karl Max Walthard (1895-1971), President 1949-1950  Walthard grew up in Bern and Frankfurt, Germany (see Figure 14).He studied medicine in Bern and trained in Bern and Munich (W.Spielmeyer).For 10 years (1914-1924), he worked in Zurich with O. Veraguth in the Department of  During his presidency, the international relationships with other national societies were strengthened.Several Swiss neurologists were invited in 1950 to attend the meeting of the Association of British Neurologists.The same year the SNG meeting took place in Lugano, for the first time in history together with another (the Italian) national Society.
Lu ¨thy grew up in Solothurn.He studied medicine in Zurich, Munich, Geneva and Bern and trained in Paris and Hamburg (M.Nonne).He obtained the 'venia docendi' from the University of Zurich in 1931 in internal medicine, a discipline to which he remained linked throughout his entire career.The same year he started a private practice in Zurich, while being in charge of neuropathological examinations at the University.In 1950, he became associate professor, and in 1955 Extraordinarius and Minkowski's successor as chair of the University Neurology Department.His research focus was neuropathology, but he made also clinical contributions (including the description of the 'bottle sign' in median nerve palsy, which was named after him, and of sensory disturbances in amyotrophc lateral sclerosis). 42e served the SNG board for 20 years (1936-1956).During his presidency, the SNG meeting took place in 1953 in Vevey with the Belgian Society and the member fees were raised from 10 to 30 Swiss francs per year.During the 1953 meeting in Zurich, the 100th anniversary of von Monakow was celebrated.
An obituary was written by Mumenthaler, 43 in which his precise and logic thinking, international reputation and distinguished and controlled (but also warm and caring) manners were described.16.Ernst Frauchiger (1903-1975), President 1953-1956  Frauchiger grew up in Langenthal (BE) (see Figure 16).He studied medicine in Geneva and Zurich.He trained in Zurich with Veraguth.His research focused on neurological diseases of animals as models for similar human diseases, with a special emphasis on bovine and equine CNS diseases.In 1933, he received the 'venia docendi' from the University of Zurich in comparative neurology.At the Veterinary Faculty of the University of Bern, he founded the 'Institute of Comparative Neurology' (later renamed Division of Neurological Sciences).For 24 years (1944-1968), he chaired the Department of Animal Neuropathology.He wrote seminal book on 'Neurological diseases of cattle' (1941) and 'Comparative neuropathology of humans and animals' (the latter with W. Hoffmann, 1957), and also wrote several works about comparative psychology. 44In addition to this appointment, he continued seeing patients in a private practice he had opened in 1948.
Obituaries were written by R. Fankhauser (the successor of Frauchiger) and D. Klein.The latter underlined his distinguished appearance, sense of humour and humanistic interests which included (oriental) philosophy and sculpture. 45Krayenbu ¨hl first served the SNG as secretary and vice president (1949-1956).In 1953, he established a Swiss Neurosurgical Working Group under the umbrella of the SNG, which meant that all Swiss neurosurgeons were also members of the SNG.During his presidency, the 50th anniversary of the Society was celebrated on the occasion of the meeting in Basel from 15-16 November 1958.Minkowski gave an introductory lecture on the history of the Society. 2 In 1957, the criteria to award the Bing prize (see above) were defined.
Articles about him were written by others including G. Weber, E. Zander, K. Akert and M. Mumenthaler [47][48][49] in which, besides his international standing (W.Penfield described him as the 'Europe's complete neurosurgeon, a Leonardo da Vinci in the versatility of his hand and mind'), his humanity, honesty and modesty were stressed.His motto was 'Der Neurochirurg ist ein Neurologe, der operieren kann' ('a neurosurgeon is a neurologist who knows how to operate'). 50.Theodore Alfred Ott (1909-1981), President 1959-1963 (see Figure 18   electroencephalography at the hospital cantonal, later 'Centre Hospitalier Universitaire Vaudois' in 1954, and remained as its director until his retirement in 1976.Since 1993, the Swiss Academy of Medical Sciences has been awarding the Theodore Ott Prize.In accordance with the will, the prize is given to researchers or research groups who have made particularly outstanding contributions. During his presidency, the SNG met for the first time with the German Neurological Society (1960, Zurich).
Ba ¨rtschi-Rochaix grew up and studied medicine and biology in Bern and Geneva.After training in neurophysiology with W. R. Hess, neurology with M. Minkowski and neurosurgery with H. Krayenbu ¨hl in Zurich, he worked as a neurologist in private practice in the city of Bern and was one of the first in Switzerland to put an EEG device into operation in his practice.The Swiss Association for Electroencephalography (later Swiss Society for Clinical Neurophysiology) was founded on 30 October 1948 in the practice rooms, which he ran with his wife Fanny, a rheumatologist. 51As a scientifically interested neurologist with academic ambitions, he was consultant at the University Medical Outpatient Department of the Inselspital (which had no neurological facility at that time).He obtained the 'venia docendi' from the University of Bern in 1949 with a thesis on 'migraine cervicale', for which he gained international recognition.The described syndrome was even awarded the eponym 'Ba ¨rtschi-Rochaix syndrome 24 '.From 1953 to 1956, he took care of EEG laboratory (which had been just founded) at the Inselspital on a part-time basis.Subsequently, he accepted a call to Alexandria in Egypt to take up the chair of neurology in 1956.But due to the Suez crisis, he had to leave Egypt in the same year and returned to Bern.Ba ¨rtschi-Rochaix's later scientific interest was focused on multiple sclerosis (MS), especially its epidemiology.In addition to this, he also wrote an account on his experiences in Egypt and, under the pseudonym 'Berto Zimmerwalder', an entertaining novel about hospital life at the Inselspital, where he ridiculed exponents of the medical faculty.
Ba ¨rtschi-Rochaix served the SNG board as secretary and as vice president (1956-1963).During his presidency, the SNG held the spring meeting in May 1965 together with the French Neurological Society in Paris.Mumenthaler acted as his secretary and recalled the excellent hospitality offered to the board meetings in his house in Belp.In 1964, the SNG had 164 members.St. Gallen.After 1975, he performed socio-medical tasks for the Disability Insurance Commission of the Cantons of St. Gallen and Appenzell I. R., in addition to neurosurgical consulting.In the SNG board, Weber first served as secretary and vice president (1963-1966).
During his presidency, the SNG had joint meetings with the Austrian (1968, Bad Ragaz) and with the Dutch and Luxembourg (1969, Rigi Kaltbad) neurological societies.In 1967, the SNG proposal of having neurology being examined during the final examination in internal medicine by a neurologist was accepted.), where he did microscopic studies with K. Engel.After the unexpected death of R. Magun, the head of neurology in Bern, Mumenthaler was appointed to this post in 1962, first as Extraordinarius and in 1966 as Ordinarius.At this time, he developed the department to a model facility.Mumenthaler also had developed a great didactic commitment which continued during his whole life by cultivating a very active lecture activity and by writing several textbooks; some of which experienced many editions and were translated into several languages.Mumenthaler was involved in numerous academic, hospital, military and professional-political bodies in Switzerland and abroad, and he also worked for the International Committee of the Red Cross.Particularly worth mentioning is his many years of editor-in-chief of the Journal of Neurology which he had transformed from German language to an international journal.
Prior to his presidency, he was secretary and vice president (1966-1969) of the SNG.During his presidency, the SNG held a meeting with the Swiss neuropathologists (1970, Bern).
An obituary was written by C.W. Hess and C. Bassetti, 52 in which his human approach to the patients, his precision in the clinical observation, and clarity in diagnostic reasoning as well as his correctness, generosity and efficiency were emphasized.Following the angiographic studies of G. Krayenbu ¨hl and G. Yasargil in Zurich, it was P. Huber in Bern who founded the first division of neuroradiology in the country in the 1960s. 56 An obituary was written by L. Kappos. 57.Anton Meyer (1918-1993), President 1975-1977 (see Figure 24).Meyer grew up in Menznau and studied medicine in Basel.He trained in neurology with M. Minkowski.In 1956, he opened a private practice as a neurologist and psychiatrist in Lucerne.From 1956 to 1983, working part-time as staff physician and consultant neurologist, he was responsible of the EEG station at the Cantonal Hospital in Lucerne.
During his presidency, the SNG chose for the second time stroke as the main topic of its meeting (in 1957, the main topic had been the cerebral venous thrombosis).Baumgartner grew up in Waldshut in southwest Baden-Wu ¨rttemberg, Germany.He studied medicine in Freiburg im Breisgau, where he engaged in experimental research with neurophysiologist Richard Jung using microrecordings in the optical cortex of the cat.Following a research period in physiology in Philadelphia (PA), he obtained the 'venia docendi' from the University of Freiburg in Freiburg im Breisgau (Germany) in 1961.For 24  years (1967-1991), he chaired the Neurological University Department in Zu ¨rich, initially as Extraordinarius, from 1970 as Ordinarius.There he established a very active neurophysiological research unit.To acquire the necessary experience for research in primates, he accomplished in 1977 a 1-year sabbatical with G. Poggio at the John Hopkins University in Baltimore.Together with his research collaborators R. van der Heydt and E. Peterhans, he demonstrated in 1984 the neuronal correlate for illusory contours in area 18 of the visual cortex of primates.For 17 years  (1971-1988), he was co-editor-in-chief of the SANP.
In the SNG board, Baumgartner served first as vice president (1978-1980).Under his presidency, a joint meeting with Dutch colleagues took place in Amsterdam in May 1981.Another joint meeting with both the German Society of Neurology as well as the Austrian Society of Neurologists and Psychiatrists was held in Hamburg in October 1982.A further highlight was the joint meeting with the   During his presidency, the SNG meetings had as main topics tick-borne encephalitis (1986, Neucha ˆtel), AIDS   (1987, Geneva) and neuropsychology (1988, Basel).In 1987, the SNG had 295 members.
Regli grew up in Chiasso (TI).He studied medicine in Zurich where he trained in neurology with F. Lu ¨thy and G.During his presidency, one SNG meeting was held with the Swedish Neurological Society (1990, Interlaken).His research focus is neuroimmunology, especially autoimmune neuropathies.For 20 years (1995-2015), he was co-editor-in-chief of the SANP.He also served as president of the European Neurological Society (1996-1997).
He first served the SNG board as secretary (1985-1989).During his presidency, the SNG hosted the French (1994, Lausanne) and met the German (1994, Bonn) neurological societies.On the occasion of the general meeting of the SNG on 5 May 1994 in Lausanne, a revision of the postgraduate training programme was decided, which included the extension of the total duration of training from 5 years to 6 years.
