French biologists

Paul Wintrebert (1867–1966) was a French embryologist and a theoretician of developmental biology.
He coined the term cytoskeleton (cytosquelette) in 1931.He held radical epigenetic views. In his 60s, he published a trilogy in which he describes his position on life process and living being: Le vivant créateur de son évolution (The living being is the creator of his own evolution) (1962), Le développement du vivant par lui-même (The self-development of the living being) (1963), and L'existence délivrée de l'existentialisme (Existence delivered from existentialism) (1965).He was a critic of the mutationist theory of evolution. His views have been described as a "biochemical Lamarckism".

Paul-Louis Simond (30 July 1858 – 3 March 1947) was a French physician, chief medical officer and biologist whose major contribution to science was his demonstration that the intermediates in the transmission of bubonic plague from rats to humans are the fleas Xenopsylla cheopis that dwell on infected rats.

Lucie Gabrielle Randoin (11 May 1888 – 13 September 1960) was a French biologist, nutritionist, and hygienist. She was made a commander of the Legion of Honour in 1958 and is known for her research on vitamins.

Gaston Ramon (30 September 1886 – 8 June 1963) was a French veterinarian and biologist best known for his role in the treatment of diphtheria and tetanus.
He was born in Bellechaume (Yonne, France) and attended l'École vétérinaire d'Alfort from 1906 to 1910. In 1917 he married Marthe Momont, grandniece of Emile Roux.
During the 1920s, Ramon, along with P. Descombey, made major contributions to the development of effective vaccines for both diphtheria and tetanus. In particular, he developed a method for inactivating the diphtheria toxin and the tetanus toxin using formaldehyde which, in its essentials, is still used in vaccines manufactured today. He also developed a method for determining the potency of the vaccines, an essential element required for the reproducible production of these pharmaceuticals.
He received 155 Nobel Prize Nominations but never received the prize.A collection of his papers is held at the National Library of Medicine in Bethesda, Maryland.

Louis Herbert Manceaux (1865–1934) was a French physician, parasitologist, and co-discover of Toxoplasma gondii with Charles Nicolle in 1908.

He developed a rabies vaccine which had some experimental success in laboratory animals.

Félix Dujardin (5 April 1801 – 8 April 1860) was a French biologist born in Tours. He is remembered for his research on protozoans and other invertebrates.

Alain Bombard (French pronunciation: [alɛ̃ bɔ̃baʁ]; Paris, 27 October 1924 – Paris, 19 July 2005) was a French biologist, physician and politician famous for sailing in a small boat across the Atlantic Ocean without provision.
