Rodolphe Paul Marie Wytsman (11 March 1860 – 2 November 1927) was a Belgian Impressionist painter. He trained at the Académie Royale des Beaux-Arts in Brussels, and was one of the founding members of Les XX, a group of avant-garde Belgian artists.
Georges Henri Roger (4 June 1860 – 19 April 1946) was a French physiologist born in Paris. He studied medicine in Paris, where he later became a professor of experimental pathology and physiology. In 1930 he was appointed dean of the medical faculty.
In the field of experimental pathology, he performed research of cholelithiasis and hepatic disease. Among his written works were articles on diseases of the liver, gastro-intestinal tract and spinal cord. In addition his 1897-98 lectures at the University of Paris were translated into English, and published as "Introduction to the Study of Medicine" (1901)
With Georges-Fernand Widal (1862-1929) and Pierre Teissier (1864-1932), he was co-author of the 22-volume Nouveau traité de médecine (New Treatise of Medicine), which was a comprehensive French masterpiece of anatomy and pathology. His name is lent to the eponymous "Roger's reflex"; a term that is sometimes used to describe excessive salivation due to irritation of the lower part of the esophagus.
Batty (Jean-Baptiste) Weber (1860–1940) is considered to have been one of Luxembourg's most influential journalists and authors, contributing much to the development of the country's national identity. His style is characterized by his sense of humour and skillful use of irony.
Gustaaf Adolf Frederik Molengraaff (27 February 1860 – 26 March 1942) was a Dutch geologist, biologist and explorer. He became an authority on the geology of South Africa and the Dutch East Indies.
Gustaaf Molengraaff studied mathematics and physics at Leiden University. From 1882 he studied at Utrecht University. As a student he made his first journey overseas when he joined the 1884–1885 expedition to the Dutch Antilles led by Willem Frederik Reinier Suringar and Karl Martin. He became PhD with a thesis on the geology of Sint Eustatius. He studied crystallography in Munich, where he also took the opportunity to study the geology of the Alps nearby.
In 1888 Molengraaff took a job as a teacher at the University of Amsterdam. Before his assignment courses in geology were given by the chemist Jacobus Henricus van 't Hoff. During his assignment in Amsterdam, Molengraaff travelled to South Africa to study gold deposits (1891) and to Borneo (1894) where he explored large parts of the inland. Teaching at Amsterdam was not to his liking, because there were too little materials and students available.
In 1897 Molengraaff became "state geologist" of the Transvaal Republic. His task was to start the geological survey of the Transvaal. While mapping the Transvaal he discovered the Bushveld complex. In 1900 he got involved in the Second Boer War and had to return to the Netherlands. This gave him time to write a report on the geology of the Transvaal, and travel to Celebes, where he (again) studied gold deposits.
Due to his reputation as a geologist he could return to South Africa in 1901 to work as a geological consultant. One of his assignments was to describe the newly found Cullinan diamond for the Central Bank of South Africa. Meanwhile the Boer War still had his attention. One of his ideas was to give each soldier a small tin identity card, which later became practice in armies around the world.
In 1906 he became professor at Delft University and this time he got enough resources and students to make his work successful. The same year he became member of the Royal Netherlands Academy of Arts and Sciences. In 1910-1911 he led a geological expedition to Timor. His research at Delft was mainly on the material collected during that expedition, and on the geology of the Netherlands. In 1922 he was a guide, along with A L Hall, of the Shaler Memorial Expedition to South Africa, organized by Harvard University. On the expedition he met Alexander Du Toit, both geologists were among the (at that time rare) supporters of Alfred Wegeners' continental drift theory.
Molengraaff was a close friend of W. F. Gisolf, who named his youngest son after him but died in a Japanese concentration camp.
Molengraaff retired in 1930.
Gustav Killian (2 June 1860 – 24 February 1921) was a German laryngologist and founder of the bronchoscopy.
Eduard Kaufmann (24 March 1860, Bonn – 15 December 1931, Göttingen) was a German physician.
The disease Abderhalden–Kaufmann–Lignac syndrome is named for him.
Henri Albert Hartmann (16 June 1860 – 1 January 1952) was a French surgeon. He wrote numerous papers on a wide variety of subjects, ranging from war injuries to shoulder dislocations to gastrointestinal cancer. Hartmann is best known for Hartmann's operation, a two-stage colectomy he devised for colon cancer and diverticulitis.
Johannes Fabry (1 June 1860, in Jülich – 29 June 1930, in Dortmund) was a German dermatologist.
He studied medicine at the universities of Bern and Berlin, receiving his doctorate in 1886. Following graduation he trained in dermatology under Joseph Doutrelepont at the University of Bonn and with Hugo Ribbert in Zürich. From 1889 to 1929 he was chief medical officer of the Skin Clinic at the Dortmund municipal hospital, which under his guidance, became a leading center for dermatology.His name is associated with "Fabry disease", a rare, inherited metabolic disease characterized by telangiectatic skin lesions, kidney failure and disorders of the cardiovascular, gastrointestinal, and central nervous systems. In 1898 he described dermatological features of the disease in a 13-year-old boy, naming the condition "purpura haemorrhagica nodularis". The disease is also called "Anderson-Fabry disease", named along with British surgeon William Anderson, who independent of Fabry, reviewed the progression of the disease over nearly 20 years in a 39-year-old patient.
Serafino Belfanti (March 28, 1860 – March 6, 1939) was an Italian immunologist, founder of the Istituto Sieroterapico Milanese, the first Italian medical and vaccine research institute.
He was born in Castelletto sopra Ticino, near Novara.
After graduating in medical sciences, he worked at the Pasteur Institute in Paris and later with Prof. Koch. In 1932 he was made an Italian senator honoris causa.He died in Milan in 1939.
Émile Charles Achard (24 July 1860 – 7 August 1944) was a French internist born in Paris.In Paris, he served as médecin des hôpitaux (from 1893), later becoming a professor of general pathology and therapeutics. In 1910, he was appointed professor of internal medicine at the University of Paris (Hôpital Beaujon). During his career, he also served as a physician at Hôpital Cochin.
In 1896, along with Raoul Bensaude (1866–1938), he identified a disease he called paratyphoid fever. They were able to isolate the cause of illness to a microbe now classified as salmonella paratyphi B.
A postmenopausal condition known as "diabetic-bearded woman syndrome" is sometimes referred to as "Achard-Thiers syndrome", and the eponymous "Achard syndrome" is a disorder characterized by arachnodactyly, brachycephaly, a receding lower jaw and joint laxity in the extremities.In 1897, along with internist Joseph Castaigne (1871–1951), he developed a urinary test using methylene blue dye for examining the excretory function of the kidneys. The procedure was to become known as the "Achard-Castaigne test". With Castaigne and Georges Maurice Debove (1845–1920), he published Manuel des maladies du tube digestif.
