Paul Julius Möbius

Paul Julius Möbius (January 24, 1853 - January 8, 1907) was a German neurologist who was born in Leipzig. Prior to entering the medical field in 1873, he studied philosophy and theology at the Universities of Leipzig, Jena and Marburg.

Möbius spent most of his medical career in Leipzig, doing clinical work as well as being a physician in his private practice. In the early 1880s, he was an assistant to neurologist Adolph Strümpell at the Medizinischen Poliklinik. He was a prolific writer and is well-known for publications in the fields of neurophysiology and endocrinology. He was also an editor of Schmidt's Jahrbücher für die gesammte Medicin.

Möbius made pioneer contributions towards the understanding of how some mental illnesses occur. He is credited for providing a distinction between exogenous and endogenous nerve disorders, and introduced ideas concerning the etiology of hysteria.

His name is associated with Möbius syndrome, a disease he identified as "nuclear atrophy". This is a rare type of palsy associated with paralysis of the cranial nerves VI and VII. This results in the patient having a masklike facial expression along with many other abnormalities such as drooling, crossed eyes, speech difficulties and problems swallowing.

Work

Today his most historically significant contribution to science is his work on the psychogenics of psychiatric and mental illnesses, such as hysteria. For the first time in the German-speaking world he postulated psychological causes of disease. For this reason and because of his convincing arguments for the therapeutical effects of electrotherapy, Sigmund Freud referred to Möbius as one of the fathers of psychotherapy.

A further important contribution is to have given his friend, the psychiatrist Emil Kraepelin, important ideas to the differentiation and systematisation of mental illness. Moebius had only made one, on the causes of diseases based classification of nervous and mental diseases. Its subdivision in endogenous and exogenous errors has long been preserved and was leading the way for the psychiatry and neurology of the 20th century. Endogenous errors established in the nervous system itself, manifested as degeneration. In the long term Möbius thus paved to way for eugenics and the crimes of psychic and neurotic disease in German naziism. Also, Möbius syndrome bears his name, which he first described in 1888; and he pointed the way to understanding the cause of the endocrinological disorder Graves' disease.

Moebius won a still dubious fame by his pamphlet "On the Physiological Idiocy of Women" (Halle: Marhold 1900). He received the greatest contemporary recognition for carving out his own territory with this work. The key message of the work not only postulated that "idiocy of woman", but also tried to impose this on already dubious methods. Moebius received plaudits for this piece, but also criticism, such as The Anti-feminists (1902) by Hedwig Dohm. In further response to Moebius were written Women and Intellectualism by Oda Olberg in 1903 and Feminism and Science by Johanna Elberskirchen in 1902. Elberskirchen said: "The truth is that when scholars make opinions concerning females, they are too much man (Mann) and too little or not at all scientifically reasoning human (Mensch)." (Elberskirchen 1902 p. 4) In other writings (such as Sex and Head Size) Moebius tried to support his theses but his comments actually showed his misunderstanding of brain anatomy and brain physiology. "On the Physiological Idiocy of Women" went through eight editions during his lifetime. In the later editions Moebius published letters from women and men which he had received for and against the book. These letters accounted for almost half of the book at the end.

In the play Weiningers Nacht by Joshua Sobol, Moebius appears as a follower of the philosopher Otto Weininger, whom he accused of plagiarism.
