French dermatologists

Albert Sézary (26 December 1880, Algiers – 1 December 1956, Paris) was a French dermatologist and syphilogist.
He served as a hospital interne in Algiers (from 1901) and Paris (from 1905), where he worked with neurologists Joseph Jules Dejerine and Fulgence Raymond and dermatologists Lucien Jacquet and Edouard Jeanselme. He received his medical doctorate in 1909, and from 1919 to 1926 was laboratory chief in the clinic for skin and syphilitic diseases at the Hôpital Saint-Louis. In 1927, he became an associate professor for skin and venereal diseases, and two years later was appointed chef de service at the Hôpitaux Broca and Saint-Louis.In 1921 he introduced the combination of arsenic and bismuth for the treatment of syphilis. He also proposed pentavalent arsenic as a treatment for general paresis of the insane.

Lucien-Marie Pautrier (2 August 1876, in Aubagne – 9 July 1959, in Strasbourg) was a French dermatologist.

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.

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.

Charles-Paul Diday (1812 – January 8, 1894) was a French physician born in Bourg-en-Bresse.
He studied medicine in Paris, and later became chief surgeon at the Antiquaille in Lyon. He was founder of the Gazette médicale de Lyon, and for 34 years was general secretary of the Société de Médecine in Lyon.
He specialized in research of venereal disease, particularly congenital syphilis. His Traite de la syphilis des nouveau-nes et des enfants a la mamelle (A Treatise on Syphilis in New-Born Children and Infants at the Breast) was considered a landmark work on congenital syphilis, and has been translated into English.
In the prevention of the spread of venereal disease in France, Diday advocated mandatory distribution of condoms in houses of prostitution. He also proposed that all individuals possess a medical certificate of health and disease as a "sanitary passport". Diday believed that marriage was a prophylactic, stating: "Marriage prevents rapid consumption produced by the venereal excess by excluding the attraction of novelty and subjecting physical instinct to a more sublime moral goal".

Marie-Guillaume-Alphonse Devergie (February 15, 1798 – October 2, 1879) was a French dermatologist born in Paris.
In 1834 he became a physician of Parisian hospitals (médecin des hôpitaux), and in 1840 succeeded Laurent-Théodore Biett (1781–1840) at the Hôpital Saint-Louis, where he practiced medicine until his retirement. During his career he was also associated with the Hôpitaux Bicêtre and St. Antoine. In 1874 he was elected president of the Académie de Médecine.
In 1856 Devergie was the first to describe a chronic papulosquamous disorder known as pityriasis rubra pilaris, also referred to as "Devergie's disease", a term introduced by Ernest Henri Besnier (1831-1909) in 1889.In 1854 he published an important textbook on skin diseases titled Traité pratique des maladies de la peau.
When he retired, Devergie donated his collection of dermatological watercolors to the Parisian hospital administration. This donation was instrumental in creation of a medical museum at Hôpital Saint-Louis.Devergie was one of the founders of forensic medicine in France, and was co-publisher of the journal Annales d’hygiène publique et de médecine légale with Mathieu Orfila (1787–1853), Gabriel Andral (1797–1876), Jean-Étienne Dominique Esquirol (1772–1840) and François Leuret (1797–1851). In 1836 he published a two-volume book on judicial medicine called Medecine legale, theorique et pratique.

Robert Degos (1904–1987) was a French dermatologist who described several dermatoses including Degos disease which he first described in a seminal paper published in 1942 in the French journal of dermatology and syphilology.
