The verdict came in a week ago and the Nobel Prize in Physiology or Medicine was awarded to Karl Diesseroth, MD, PhD, Peter Hegemann, PhD and Georg Nagel, PhD. The award for the discovery and implementation of optogenetics in neuroscience. This technique is a revolutionary one for neuroscience and this award was expected for some time for these researchers. Since the Prize was publicized there has been an explosion of images, videos, and social media posts featuring Diesseroth, his colleagues, and family members. In this age of social media, there are an army of influencers using the story to get views. For my part, I will just say congratulations. The story I want to tell here is more about psychiatrists and the Nobel Prize.
Many years ago, when I worked at an acute care hospital, I was the department member who presented unusual grand rounds. I gave one on the mathematicians Paul Erdös and Kurt Gödel reviewing their accomplishments, creativity, and eccentricities. I followed it up with a grand rounds on the first psychiatrist to receive a Nobel Prize in 1927 – Julius Wagner-Jauregg. He discovered the treatment of dementia paralytica (late-stage neurosyphilis) with malaria carrying mosquitos. It is important to recall that this form of neurosyphilis made up 10-20% of all asylum care at the time, this was a pre-antibiotic era and at the time late-stage neurosyphilis (or General Paresis of the Insane/GPI) was a uniformly fatal illness. An estimated 30% of this population recovered with malaria inoculation and concomitant treatment of the malaria with quinine.
The downside to the treatment and subsequent controversy was the fact that 10-15% of patients died as a result of the malaria. This therapy disappeared entirely with the advent of the antibiotic era in the 1940s. Wagner-Jauregg is described as a psychiatrist, but the training in those days was not standardized. After medical school he trained with a histopathologist, then in a psychiatric clinic for 4 years, and eventually headed a psychiatric clinic at the University of Graz in Austria. His academic focus there was on goiter, cretinism, and iodine. He produced 80 publications during his academic career and succeeded two highly regarded psychiatrists in clinics.
His career was not without controversy. First, he was a Nazi sympathizer. His application to that party was denied because his first wife was Jewish. Second, he promoted eugenics. Third, he administered electric shocks to soldiers for “malingering” and several of them died leading to a formal inquest. Fourth, some did not find the malaria therapy of neurosyphilis that impressive probably because the cure was also fatal to a significant number of patients. Like any infectious disease, outcomes depend on host factors and neurosyphilis lead to significant physiological compromise and deconditioning. Fifth, he was also credited with calling for the iodination of salt to prevent goiter based on his thyroid studies, but subsequent work determined there was no direct connection to that policy being adopted in Austria as it occurred decades after his research and at least 2 other research groups were credited. He had a problematic personality and believed that the usual rules did not apply to him. Although I find century old personality critiques stretching credibility – I agree with several authors that his accomplishments were overshadowed by the controversies. The best proof of overshadowing is that most people are not aware of his name or accomplishments – even though he won the Nobel and Freud did not, Freud is more widely known and studied to this day.
Wagner-Jauregg and Freud were contemporaries. Freud was 1 year older and at times they influenced each other’s career. Wagner-Jauregg was called upon to write a critique of Freud’s work for an academic appointment and Freud provided expert testimony in a hearing where Wagner-Jauregg was accused of killing shell shocked soldiers with some type of electrotherapy. From 1925-1938, Freud was nominated 12 times for the Nobel Prize in Physiology or Medicine and once for the Nobel Prize in Literature in 1936 but never won the award. In his biography, Peter Gay writes that Freud thought about the award constantly, hoped to get it, and was disappointed when he did not.
Depending on the author, both Freud and Wagner-Jauregg are written about as neurologists or psychiatrists and Freud is occasionally called a psychologist. This is because of a lack of uniformity in training and credentialling in the 19th and early 20th century. When you read about many of these prominent figures you will find that they head neurology and psychiatry clinics interchangeably and in many cases were also neuropathologists, neuroanatomists, and histologists. A good example if the photo at the top of this post. It is a photo of Alois Alzheimer (back row 6th from the left) with his colleagues in neurology clinic (title Nervenklinik 1910-1911). The strict translation is “psychiatric clinic or mental hospital”. At the time this was in the Munich Psychiatric Clinic headed by Emil Kraepelin.
If we think of criteria to apply to determine if a researcher is a psychiatrist or not dating back to that time, I suggest the following:
1) Physicians who made major contributions to
neuropsychiatry prior to the formal establishment of the fields of psychiatry
and neurology. Charcot, Wernicke, Alzheimer, Kraepelin, and
Freud practiced across both domains.
2) neuropathologists or neurologists who were also
psychiatrists or had a major interest in psychiatry; note that Freud was a
Privadozent in neuropathology and Adolph Meyer came to the US to work as a
neuropathologist. António Egas Moniz is typically cited as a
neurologist who practiced psychiatry.
3) physicians trained in both neurology and psychiatry. There were really 2 waves of
neuropsychiatry. In the US practically
all psychiatrist before 1935 practiced both and it was revived for military
psychiatry in WWII. After graduating from medical school in 1901 von Economo
spent a year working in an internal medicine clinic and over the next four
years worked at various clinics in Europe with Marie, Kraepelin, Alzheimer, and
Oppenheim learning psychiatry, neurology, and hypnosis. He returned to the
University of Vienna in 1906 and was appointed Professor of Neurology and
Psychiatry in 1921.
4) physicians board certified in psychiatry by the ABPN –
modern standard – can occur even if the psychiatrist does not practice or see patients.
5) physicians who
headed psychiatric clinics or hospitals – many prominent examples like Franz
Nissl who did research with Alzheimer and Kraepelin and is known for
histopathological discovery but he eventually replaced Kraepelin as Professor
of Psychiatry and Director of the Psychiatric Clinic at the University of
Heidelberg.
6) attending physician in psychiatry.
7) physicians trained by self-identified psychiatrists.

Looking at the table of Nobel laureates Only Wagner-Jauregg and Deisseroth practiced clinical psychiatry. Kandel was trained and board certified as a psychiatrist but worked as a basic science researcher. I would count all three as psychiatrists.
Of the remaining laureates the following completed medical degrees Camillo Golgi (University of Pavia 1865), Santiago Ramón y Cajal (University of Zaragoza 1873), Otto Loewi (University of Strassburg -1896), Henry Dale (Cambridge University 1909), António Egas (University of Coimbra 1899), and Ulf von Euler – (Karolinska Institute 1930).
Two of the laureates were trained as PhD scientists Julius Axelrod (George Washington University - 1955 and Paul Greengard (Johns Hopkins University -1953). The remaining three laureates were trained as physicians and scientists - John Eccles (MB, BS, MD -University of Melbourne) (Oxford - DPhil 1929, Bernard Katz (MD University of Leipzig – 1934) (PhD University College London – 1938), Arvid Carlsson – (MD, PhD University of Lund – 1951). The interesting observation in this case is that most of the Nobel awards were to scientists with medical training or combined MD/PhD training. There is some selection bias since the category is Medicine or Physiology.
Even though neuroscience is considered a relatively new discipline it has historically had a close relationship to psychiatry for over 100 years. Psychiatry has developed out of the close relationship with neurology and neuroscience and that seems to be lost by many modern-day critics. That seems to be semantics more than anything else. Just because you could not get a BS in Neuroscience in Cajal’s era did not mean neuroscience did not exist.
In addition to Freud there were several additional neuropsychiatrists or possibly psychiatry adjacent researchers who were nominated but never received the Noble. Ugo Cerletti (1877–1963) — an Italian neuropsychiatrist had correspondence with the Nobel committee and actively wanted the prize, but controversy about the method as well as conflict with his student Lucio Bini who subsequently patented his own machine may have been a factor in him not getting it. Others include Joseph Babinski, Vladimir Bekhterev, Henry Head, Eduard Hitzig, and Hans Berger.
One of the fascinating aspects in training and reading about psychiatry is the tremendous diversity in training that occurred. I previously asked the question whether the field though standardization has become less intellectually stimulating than it was in the past. I used von Economo’s career as an example. With standardization you can no longer go through a lab, a neurology clinic, or a psychiatry clinic in 4-year blocks and come out studying and researching whatever you want. It is rare these days to see an MD doing basic science research, but fairly common to see them doing clinical research. The neuropsychiatrists of the early 20th century are not the neuropsychiatrists of the early 21st century. Before the board certification rule in the US in 1934, all psychiatrists were considered neuropsychiatrists. Today they come in three forms – double board certified in psychiatry and neurology, psychiatrists with a neuropsychiatry fellowship or neurologists with a behavioral neurology fellowship, or self-proclaimed. None of the psychiatrists doing this work are very visible. Most of the patients they treat are not seen in routine outpatient practice. They are more likely to be seen in acute care settings and specialty clinics.
The reason why the Nobel is so important in psychiatry is not because of the scorecard. Having people of that caliber in the field, especially when they take an active role in teaching, mentoring and research brings the field up to a higher level. I think it worked that way in the early 20th century when Warner-Jauregg made a landmark finding in biological psychiatry. It worked that way when Kandel made similar discoveries in plasticity and memory in the 1970 (8). I hope it works that way now with the award to Deisenroth. I hope his work is being studied in psychiatry resident seminars across the country.
Not that I expect it will stimulate any more MD, PhDs – but I hope it stimulates people to think about what a psychiatrist should know and how it improved our knowledge of the field. I hope it encourages all of us to expand beyond the roles that have been defined for us by businesses, administrators, or people who otherwise attempt to intellectually restrict the field.
