Eduard Raehlmann (19 March 1848, Ibbenbüren – 1 September 1917, Weimar) was a German ophthalmologist.
He studied medicine at the Universities of Würzburg and Halle, obtaining his doctorate at the latter institution in 1872. In 1875, he received his habilitation at the University of Strassburg, and in 1879 succeeded Georg von Oettingen as professor of ophthalmology at the University of Dorpat. After 1900, he worked as a private scholar in Weimar.His primary work dealt with anatomical and pathological investigations of the cornea, as well as studies involving amyloid degeneration of conjunctiva and research of retinal detachment. In the Baltic states, he was at the forefront in the fight against trachoma. At Weimar, he conducted research of color perception and color photography.

François Laurent (8 July 1810 – 11 February 1887) was a Belgian historian and jurisconsult.

Eligio Perucca (28 March 1890 in Potenza – 5 January 1965 in Rome) was an Italian physics instructor and researcher at the University of Turin in Italy in the early decades of the twentieth century. He later served a professorship at the nearby Polytechnic University of Turin. He discovered an important principle in stereochemistry in 1919, but his contribution was overlooked and forgotten until recently.

Johannes Orth (14 January 1847 – 13 January 1923 in Berlin) was a German pathologist born in Wallmerod.
He studied medicine at the universities of Heidelberg, Würzburg and Bonn, receiving his habilitation in 1872 while an assistant to Eduard von Rindfleisch at Bonn. Afterwards, he served as an assistant under Rudolf Virchow (1821-1902) in Berlin. In 1878 he became a professor at the University of Göttingen, and in 1902, following the death of Virchow, he returned to Berlin as director of the clinic of pathology.
Orth specialized in the pathological study of infectious diseases, particularly tuberculosis and endocarditis.
In 1875, he documented an account involving an autopsy of a jaundiced infant with intense yellow staining of the basal ganglia, hippocampus, the third ventricle, as well as parts of the cerebellum. However, it wouldn't be until the early 20th century that this condition would be further comprehended. In 1903, pathologist Christian Georg Schmorl (1861-1932) presented the results of 120 autopsies of jaundiced infants, with six of the cases having the staining phenomena described by Orth. Schmorl coined the term "kernicterus" (jaundice of the basal ganglia) for the yellow staining phenomenon.

Désiré Charles Emanuel van Monckhoven (1834–1882) was a Belgian chemist, physicist, and photographic researcher. He was also an inventor and author.

François Achille Longet (25 May 1811 – 20 April 1871) was a French anatomist and physiologist who was a native of Saint Germain-en-Laye, Yvelines.
He was a student of François Magendie (1783–1855), and a pioneer in the field of experimental physiology. In 1853 he attained the chair of physiology of the Faculté de Médecine in Paris. One of his better known students was German physiologist Moritz Schiff (1823–1896).
Longet is remembered for extensive research of the autonomic nervous system, and physiological experiments of the anterior and posterior columns of the spinal cord in regards to sensory and motor functionality. Also, he is credited with providing a detailed comprehensive description of nerve innervation of the larynx. With Jean Pierre Flourens (1794–1867), he performed pioneer experiments on the effects of ether and chloroform on the central nervous system in laboratory animals.

Louis Francisque Lélut (1804–1877) was a French medical doctor and philosopher known for his works Démon de Socrate and L'Amulette de Pascal, where he stated that Socrates and Blaise Pascal were insane.
Born at Gy, a small village in the Haute-Saône department, he was member of the Academy of Moral and Political Sciences and researched mental illnesses and phrenology. His main work was Physiologie de la pensée, published in 1861.
During the Second French Empire he was member of the Legislative Body.

Pierre-Félix Lagrange (22 January 1857 – 22 April 1928) was a French ophthalmologist.

Abraham Kuhn (January 28, 1838 – September 15, 1900) was an Alsatian otolarynologist born in Bissersheim, Rhineland-Palatinate.
He studied under Anton von Tröltsch (1829–1890) at the University of Würzburg, then continued his education at the École de Médecine in Strasbourg. In 1870, he published his French translation of Tröltsch's Lehrbuch der Ohrenheilkunde, with the title Traité pratique des maladies de l'oreille.During the Franco-Prussian War he served with the Croix-Rouge (French Red Cross) on the battlefields of Wissembourg and Wörth. In 1873 he became a lecturer at the renamed Kaiser-Wilhelm-Universität in Strassburg, where in 1881 he was appointed associate professor of otolaryngology and director of the clinic of ear diseases. After his death, he was succeeded at Strassburg by Paul Manasse.During his career, Kuhn was one of only a handful of professors in Germany who specialized in the field of otology. Much of his scientific research dealt with comparative anatomy of the ear, in particular the labyrinth of the inner ear. He also made significant contributions on the diagnosis and treatment of ear tumors.
