Lortet was a member of numerous scientific societies, such as the Société de géographie de Lyon, being a founding member in 1858. Species with the epithet of lorteti are named in his honor; an example being the pufferfish species Carinotetraodon lorteti.

Gustave-Édouard Laguesse (23 April 1861 – 6 November 1927) was a French pathologist and histologist born in Dijon.
In 1885 he received his medical doctorate in Paris and from 1891 performed scientific research in Lille. In 1896 he became a professor of histology.Laguesse is remembered for his histopathological work involving the pancreas. In 1893 he named the small cellular clusters of the pancreas the "Islets of Langerhans", in honor of their discoverer Paul Langerhans (1847-1888). At the time of its discovery, Langerhans provided an excellent description of the structures, but offered no further conclusions as to their function. Laguesse postulated that the Islets of Langerhans produced secretions that played a regulatory role in digestion. Laguesse's research was considered a major step on the path of discovery of a new hormone in the early days of endocrinology.

Léon Labbé (29 September 1832 – 21 March 1916) was a French surgeon and politician who was born in the village of Le Merlerault in the department of Orne. He was an uncle to physician Charles Labbé (1851–1889), who first described the inferior anastomotic vein ("vein of Labbé").
From 1856 to 1860 Labbé was a hospital intern in Paris, and in 1861 earned his medical doctorate. Afterwards, he was a surgeon at several hospitals in Paris, including the Hôpital Beaujon, where he was chief-surgeon for many years. In 1879 he became a member of the Académie de Médecine.
In 1892 he was elected to the Senate representing the department of Orne. In this role, he introduced various laws of interest to the medical community, including the 1914 Loi Labbé (Labbé Law), legislation that provided compulsory anti-typhoid vaccinations for French soldiers.

Hermann Kümmell (22 May 1852, Korbach, Waldeck-Pyrmont – 19 February 1937) was a German surgeon.

In 1883 he became chief physician of the surgical department at the "Marienkrankenhaus" in Hamburg, and in 1895 was appointed surgeon-in-chief of the Allgemeinen Krankenhaus Hamburg-Eppendorf. In 1907 he became a titled professor, and in 1919 was a professor of surgery at the University of Hamburg.
Kümmell's work involved the treatment of fractures, bone implants and diseases of the spinal column. He also conducted extensive research of bladder and kidney disturbances, diseases of the chest, et al. He was among the first surgeons to advocate removal of the appendix in cases of recurrent appendicitis, and in 1886 attempted the first choledochotomy.
Among his numerous publications on surgery was Chirurgische Operationslehre, a three-volume work that he co-authored with August Bier (1861-1949) and Heinrich Friedrich Wilhelm Braun (1862-1934).
