Vocation : Healing Fields : Psychiatrist

Friedrich Meggendorfer (June 7, 1880 – February 12, 1953) was a German psychiatrist and neurologist.

Otto Lowenstein (7 May 1889 – 25 March 1965) was a German-American neuropsychiatrist who was a native of Osnabrück.
He grew up in Preußisch Oldendorf, the son of Julius Lowenstein, a merchant, and Henriette Grunewald, into a Jewish family, and, when he was 19, began to study mathematics and philosophy at the University of Göttingen, before switching to medicine in another university.In 1914 he received his medical degree from the University of Bonn, and following service as a military physician during World War I, he returned to Bonn as a neuropsychiatric assistant to Alexander Westphal. While at Bonn, he was involved in the fields of pediatric psychiatry and experimental psychology. He pursued funding from the Government of Westphalia, then developed and opened the first children's psychiatric hospital in the world. He became Chief of Staff at this new Neuropsychiatric Hospital of Bonn University (1920–1926). He became Chief Neuropsychiatrist and Director of the State Hospital for Nervous and Mental Diseases and founded the pioneering Neuropsychiatric Hospital for children, serving as its head from 1926 to 1933. This hospital continues to operate to this day and is believed to be the first specialized hospital of its kind in the world. He was the Director of the Institute for Heredity in Neurology and Psychiatry, (Institut Fuer Neurologisch–Psychiatrische Erbforschung) from 1926 to 1933. Together with his wife, Dr Marta (Grunewald) Lowenstein, he conducted hundreds of interviews to develop family histories of neurological illnesses. While in Germany he also began early research into pupillography as a means to detect and diagnose mental and neurological disorders including engineering the first machines and methodologies to assist in the study of the eye as a window to the brain.
In 1933, because of his Jewish ethnicity, he relocated to Switzerland in order to escape Nazi persecution (led by a former army colleague who was envious of his work), working as a neuropsychiatrist at the Clinique La Métairie in Nyon. He was a member of the faculty of the University of Geneva, Department of Ophthalmology, and Director of the Pupillographic Laboratory from 1935 to 1939. Under his leadership, the laboratory and the equipment pioneered there were invented and used in his researching the pupil. In 1939 he emigrated to New York City, where he was associated with New York University and later Columbia Presbyterian Hospital. In New York, he continued neuro-ophthalmological research with his research assistant Irene Loewenfeld. As he was preparing final edits to a major compendium of his life work specializing on the pupil, he was taken ill with pancreatic cancer. His work was entrusted to Dr Loewenfeld who had received her Ph.D. From the University of Bonn under Dr Lowenstein's mentorship. The work was ultimately published in the 1990s and contains his research in two volumes.He is remembered for his studies involving motion, size and functionality of the eye's pupil from a neuropsychiatric standpoint. In Germany and America, he created laboratories containing specialized equipment for research of the eye's pupil. He was particularly interested in the status of an individual's pupil during specific emotional and psychological states, as well as the condition of the pupil during periods of fatigue and alertness.
In 1957, he built an "electronic pupillograph" that incorporated infrared technology. This device was used to accurately measure and analyze the pupils' diameter, and was a forerunner to more sophisticated pupillographic instruments that were developed in later years. Lowenstein's pioneer experiments and numerous publications on pupillary topics were a major factor in bringing pupillography into American neuro-ophthalmological medicine.
Recently, a psychiatric clinic for children called Das Professor Otto Löwenstein Haus was founded at the University of Bonn in Lowenstein's honor.
He was survived by his wife Marta who died later in the same year and by his two daughters, Anne Elizabeth Löwenstein Perls of Pacific Palisades, California, and Mary Dorothy Theresa Löwenstein Rowe (aka Marieli Rowe) of Madison, Wisconsin.

Henri Legrand du Saulle (Dijon, 16 April 1830 – Paris, 5 May 1886) was a French psychiatrist.
As a young man he worked as an assistant to Bénédict Morel (1809–1873) at Saint-Yon, and also served under Louis-Florentin Calmeil (1798–1895) at the Charenton Asylum. In 1856 became a doctor to the medical faculty in Paris. Later on, he was appointed physician at the Bicêtre Hospital (replacing Prosper Lucas 1805–1885), and in 1879 succeeded Louis Delasiauve (1804–1893) as chief physician in the department for epileptics at Salpêtrière Hospital. During his career he was also associated with the Prefecture of Police, serving from 1863 as médecin-adjoint to Charles Lasègue (1816–1883).He is known for his studies on personality disorders, particularly pioneer work involving phobias and obsessive-compulsive disorders. He also performed extensive work in forensic psychiatry, being interested with the medical-judicial aspects of psychopathology.

Julius Ludwig August Koch ( KOKH, German: [ˈjuːli̯ʊs ˈluːtvɪç ˈʔaʊɡʊst ˈkɔx]; 4 December 1841 in Laichingen, Württemberg – 25 June 1908 in Zwiefalten, Württemberg) was a German psychiatrist whose work influenced later concepts of personality disorders.Koch was born in the town of Laichingen in the state of Württemberg. His father was a general practitioner physician who headed his own private insane asylum.
Koch worked as a chemist for several years and then studied medicine in Tübingen from 1863 to 1867. He subsequently worked as a physician, later joining a psychiatric hospital. In 1874 he became director of the state mental hospital in Zwiefalten (Württemberg).Described as deeply rooted in a Christian faith, Koch's first works were philosophically-minded. In 1882 he published "Epistomological Investigations" (Erkenntnistheoretische Untersuchungen), and in 1885 "Outline of Philosophy" (Grundriss der Philosophie). In 1886 his "Reality and its Knowledge" (Die Wirklichkeit und ihre Erkenntnis) was an attempt to join the philosophy of Immanuel Kant with Christian theories.
Koch argued that the body and soul are part of the natural material world, while the mind (geist) is the way through which freedom, but also a moral claim by God, are exercised. He felt that philosophical trends against the Christianity of a nation would lead to afflictions and dangers. Overall his philosophy has been described as homespun and quite dogmatic, especially with regard to the religious elements.

Adrien Alphonse Alcide Borel (19 March 1886, in Paris – 19 September 1966, in Beaumont-lès-Valence) was a French psychiatrist and psychoanalyst.

Marc Danzon was the European regional director for the World Health Organization from 2000 until 2010. Danzon, who is French, has a background working as a child psychiatrist. In February 2010, Zsuzsanna Jakab succeeded him.

Gustav Aschaffenburg (May 23, 1866 – September 2, 1944) was a German psychiatrist born in Zweibrücken.
In 1890 he received his medical doctorate from the University of Strasbourg with a thesis on delirium tremens. Later he worked as an assistant to Emil Kraepelin at the psychiatric university clinic in Heidelberg, with whom he later extensively wrote about Haltlose personality disorder. He then practiced psychiatric medicine at the University of Halle and at the Akademie für praktische Medizin in Cologne (from 1919 the University of Cologne).
In the 1930s Aschaffenburg's academic career at Cologne was terminated by the Nazi edict, Gesetz zur Wiederherstellung des Berufsbeamtentums, and he eventually emigrated to the United States, working as a professor at the Catholic University of America in Washington, D.C., and at Johns Hopkins University in Baltimore.
He wrote about the distinctions between Haltlose and Gemütlose psychopathy.
Aschaffenburg was a pioneer in the fields of criminology and forensic psychiatry. In 1903 he published an early systematic study on the causes of crime titled "Das Verbrechen und seine Bekämpfung", in which he discusses individual-hereditary and social-environmental factors, and also dismisses Cesare Lombroso's idea of the so-called "born criminal". Later the work was translated into English, and published as Crime and it's Repression (1913). It was also translated into Swedish by Olof Kinberg and Julia Kinberg.

Joseph Louis Irenée Jean Abadie (15 December 1873, Tarbes – 1934) was a French neurologist who is remembered for naming Abadie's symptom.
