University of Bonn alumni

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.

Friedrich Wilhelm Erich Leschke (23 October 1887, in Bergneustadt – 10 June 1933, in Berlin) was a German internist.
He studied medicine at the University of Bonn, receiving his doctorate in 1911 with the thesis Über die Wirkung des Pankreasextraktes auf pankreasdiabetische und auf normale Tiere ("On the effect of pancreatic extract on pancreatic-diabetic and normal animals"). He later worked at the Friedrich-Wilhelm-Stift in Bonn, at the Eppendorf Hospital in Hamburg and in the 2nd medical clinic at the Berlin Charité. In 1918 he obtained his habilitation at Berlin, where soon afterwards he became an associate professor.His name is associated with Leschke's syndrome, a condition characterized by a combination of asthenia, multiple brown pigment spots on the skin and hyperglycemia. He described the syndrome in a 1922 paper titled Über Pigmentierung bei Funktionsstörungen der Nebenniere und des sympathischen Nervensystems bei der Recklinghausenschen Krankheit.He was the author of numerous papers regarding cardiac, pulmonary and metabolic diseases. His book Die wichtigsten vergiftungen, Fortschritte in deren Erkennung und Behandlung was translated into English and published as Clinical toxicology; modern methods in the diagnosis and treatment of poisoning (1934).

Eduard Kaufmann (24 March 1860, Bonn – 15 December 1931, Göttingen) was a German physician.
The disease Abderhalden–Kaufmann–Lignac syndrome is named for him.

Alfred Gottschalk (22 April 1894 – 4 October 1973) was a German biochemist who was a leading authority in glycoprotein research. During his career he wrote 216 research papers and reviews, and four

books.Gottschalk was born in Aachen, the third of four children to Benjamin and Rosa Gottschalk, who had Jewish heritage. He was raised Catholic. He choose to study medicine, from 1912 he attended the Universities of Munich, Freiburg im Breisgau and Bonn. During the war he served in the medical corps of the German Army. He completed his medical degree in 1920, graduating MD from the University of Bonn. He completed clinical work experience at the medical schools of Frankfurt am Main and Würzburg and physiology-biochemistry studies at Bonn, that led to his first publications, an award from the University of Madrid and an invitation to work at the Kaiser Wilhelm Institute for Experimental Therapy and Biochemistry with Carl Neuberg.
In 1923 he married Lisbeth Berta Orgler; together they had one son. They separated in 1950. Gottschalk left the Kaiser Wilhelm Institute for Biochemistry in 1926 to become Director of the Biochemical Department at the General Hospital in Stettin. He left the hospital in 1934 following upheaval in Nazi Germany and entered private practice, left for England in the spring of 1939, and on to Melbourne in July. He was offered a position as a biochemist by Charles Kellaway, director of the Walter and Eliza Hall Institute (WEHI). He initially worked with yeast enzymes and fermentation, but in 1947 he joined the virus department, where he worked with Frank Macfarlane Burnet. He also taught biochemistry and organic chemistry at the Melbourne Technical College and later at the University of Melbourne. In 1945 he became a naturalized British citizen. In 1949 he received a DSc from the University of Melbourne.
He was elected a Fellow of the Australian Academy of Science in 1954. He discovered viral neuraminidase there in 1957. As Burnet stated: “In the world of biochemistry the most important contribution of the Walter and Eliza Hall Institute is regarded as Gottschalk’s discovery of the structure of the sialic acids and his recognition that an enzyme which I had characterised biologically was chemically a neuraminidase. Gottschalk’s work was masterly and it was definitive.”On his retirement in 1959, he was invited by his friend and former WEHI colleague Frank Fenner to research at the John Curtin School of Medical Research at the Australian National University. He returned to Germany in 1963, where he was appointed Guest-Professor at the Max Planck Institute for Virus Research in Tübingen. He continued active research and for his contributions to science was elected to the Fellowship of the American Association for the Advancement of Science in 1967 and received an honorary doctorate from the University of Münster (MD) in 1969.
He died in Tübingen on 4 October 1973. The Gottschalk Medal for medical research awarded by the Australian Academy of Science is named in his honour.

Alexander Ellinger (17 April 1870 in Frankfurt am Main – 26 July 1923 in Frankfurt am Main) was a German chemist and pharmacologist.
From 1887 he studied chemistry at the University of Berlin under August Wilhelm von Hofmann and at the University of Bonn as a pupil of August Kekulé. Afterwards, he studied medicine at the University of Munich, followed by work as an assistant in the institute of pharmacology at the University of Strasbourg. In 1897 he became an assistant to Max Jaffé in the laboratory of medicinal chemistry and experimental pharmacology at the University of Königsberg. In 1914 he was appointed professor of pharmacology at the newly established University of Frankfurt.He is remembered for his extensive biochemical research of several amino acids, especially tryptophan. In 1904 he isolated kynurenic acid from the urine of dogs that had been fed tryptophan. His other work included studies on the water exchange between body tissues and blood, on the formation on lymph, and with chemist Karl Spiro, he conducted investigations of blood coagulation.

Karl Wilhelm Bücher (16 February 1847, Kirberg, Hesse – 12 November 1930, Leipzig, Saxony) was a German economist, one of the founders of non-market economics, and the founder of journalism as an academic discipline.

Max Bense (7 February 1910 in Strasbourg – 29 April 1990 in Stuttgart) was a German philosopher, writer, and publicist, known for his work in philosophy of science, logic, aesthetics, and semiotics. His thoughts combine natural sciences, art, and philosophy under a collective perspective and follow a definition of reality, which – under the term existential rationalism – is able to remove the separation between humanities and natural sciences.

Richard Laqueur (27 March 1881 – 25 November 1959) was a German historian and philologist born in Strassburg.
He studied classical literature and history at the Universities of Bonn and Strassburg, and in 1904 received his doctorate of philosophy. In 1912 he was made a full professor at Strassburg, and during the same year was appointed professor at the University of Giessen. From 1914 to 1918 he performed military duties during World War I, and in 1919 returned to Giessen, where he remained until 1930. Laqueur was rector at the university in 1922/23.In 1930 he became a professor at the University of Tübingen, and two years later a professor at the University of Halle. Because he was Jewish, Laqueur was removed from his position at Halle in 1936, and in 1939 emigrated to the United States. After World War II, he returned to Germany, but was denied his former status at Halle due to bureaucratic obstacles. In 1952 he moved to Hamburg, where he was later granted an honorary professorship.Laqueur was a specialist of ancient Greek and Roman history, and was particularly interested in the economic history of their civilizations. He conducted extensive research of the ancient historians Polybius and Flavius Josephus, and made literary contributions to the Pauly-Wissowa- Realencyclopädie der Classischen Altertumswissenschaft.
