Dr. Édouard Marie Heckel (March 24, 1843 – January 20, 1916) was a French botanist and medical doctor, and director of the Jardin botanique E.M. Heckel in Marseille.
Heckel was born in Toulon, studied pharmacy and medicine, and in 1861 visited the Caribbean and Australia. In 1875, he was appointed professor in the faculty of sciences at Marseille, and in 1877 professor of medicine. He became a professor of natural history in Nancy in 1878, and is known for his studies of tropical plants and their use as medicinal plants and oilseeds.
From 1885, Heckel turned to the study of tropical plants such as medicinal or industrial oilseeds. In 1893 he founded the Colonial Institute and Museum of Marseille and creates a tropical pathology professorship at the medical school.
In 1887, he won the Prix Barbier from the French Academy of Sciences.In 1896, French botanist Jean Baptiste Louis Pierre named a genus of flowering plants (belonging to the family Meliaceae) from western central Tropical Africa, Heckeldora in his honour.In 1901, he launched the idea of creating an exhibition devoted exclusively to French colonies. This project would be supported by Jules Charles-Roux, who would become the Commissioner General while Heckel was his deputy. The exhibition was held at Parc Chanot in Marseille and was a great success from its opening on April 14, 1906 to its closure Nov. 18, 1906.

François Henri Hallopeau (17 January 1842, Paris – 20 March 1919, Paris) was a French dermatologist. He studied medicine under Alfred Vulpian and Sigismond Jaccoud. He co-founded and was secretary general of the Société Française de dermatologie et de syphiligraphie. He became a member of the Académie de Médecine in 1893.
He coined the medical term trichotillomania in 1889. He also coined the word antibiotique in 1871 to describe a substance opposed to the development of life.Selman Waksman was later credited with coining the word antibiotic to describe such compounds that were derived from other living organisms, such as penicillin.

Augustin Grisolle (10 February 1811 – 9 February 1869) was a French physician born in Fréjus.
Grisolle was a professor at the Paris faculty of medicine and a member of the Académie de Médecine. He was the author of the two-volume "Traité élémentaire et pratique de pathologie interne" (1844).
His name is associated with "Grisolle's sign", an obsolete sign once affiliated with smallpox. It involved feeling the presence of papules when the skin is stretched.

Raymond Grasset (10 January 1892 - 8 February 1968) was a French politician. He began his career as a physician. He was the Secretary (or Minister) of Family and Health from 18 April 1942 to 20 August 1944.

Gaspard Goyrand (3 February 1803 – 23 June 1866) was a French general practitioner, surgeon and politician from Aix-en-Provence. He helped treat cholera from 1835 to 1854, while serving as Deputy Mayor of Aix from 1838 to 1848.

Dominique Alexandre Godron (25 March 1807 - 16 August 1880) was a French physician, botanist, geologist and speleologist born in the town of Hayange, in the département Moselle.
Godron studied medicine at the University of Strasbourg, and during his career distinguished himself in natural sciences as well as in the field of medicine. In 1854 he became dean and professor of natural history to the Faculty of Sciences at Nancy. Here he established a natural history museum and reorganized its botanical garden (now the Jardin Dominique Alexandre Godron, renamed in his honor).
Among his numerous writings were a publication on the flora of the Lorraine region of France called "Flore de Lorraine" (1843), and the three-volume "Flore de France", a work on flora native to France and Corsica that was co-written with botanist Jean Charles Marie Grenier (1808-1875). In addition to his botanical works, he published a number of studies in the field of ethnology.Before Mendel, he discovered the main features of hybridation. In "de l'Espece et des races dans les êtres organises" he also demonstrated that hybridization in the vegetal world was, against the dominant thinking at the time, similar to hybridization in the animal world. He finally demonstrated the unity of mankind in his book dedicated to our species.
In 1846, he was honoured by botanists Jean Baptiste Mougeot and Joseph Henri Léveillé who named Godronia, which is a genus of fungi in the family Helotiaceae. Then in 1927, William Webster Diehl and Edith Katherine Cash published Godroniopsis, which is also a genus of fungi in the family Helotiaceae.

Philippe Charles Ernest Gaucher () (July 26, 1854 – January 25, 1918) was a French dermatologist born in the department of Nièvre.
He received his medical doctorate in 1882, and soon after headed a medical clinic at Necker Hospital. During the subsequent years he was an instructor at several hospital clinics in Paris. He taught classes on pathological anatomy, bacteriology and histology, as well as dermatology.
In 1902 he succeeded Jean Alfred Fournier (1832–1914) as the university chair of dermatology and syphilography. Gaucher was also founder of a journal on venereal disease called Annales des Maladies Vénériennes.He is remembered for providing a description of a disorder that was to become known as Gaucher's disease. In 1882 while still a student, he discovered the disease in a 32-year-old woman who had an enlarged spleen. At the time, Gaucher thought it to be a form of splenetic cancer, and published his findings in his doctorate thesis, titled De l'epithelioma primitif de la rate, hypertrophie idiopathique de la rate sans leucemie. However, it was not until 1965 that the true biochemical nature of Gaucher's disease was understood.

Noël Armand Fiessinger (24 December 1881 – 15 January 1946) was a French physician.
