= Madeleine Charnier = Madeleine Charnier is a French zoologist and known for her work on sensitivity of sex determination due to temperature in reptiles.

Early life and death
Charnier was born in 1919 in France and died in July 2002 in Nice, France. She had just turned 83 years old.

Research
Madeleine Charnier holds a Bachelor's degree in science from the Faculty of Sciences in Paris, which she received in 1935.

From 1955, she worked at the Faculty of Medicine in parasitology and passed certificates of coprology and hematology. She published her first scientific paper on the Common Agama which became her preferred species for research for the next 10 years (and Charnel Dutarte 1956). This is the only article she has done in collaboration during her work in Africa. The coauthor, J.-P. Dutarte is a doctor who worked on urinary tuberculosis.

In 1958, she left the Faculty of Medicine for the Faculty of Sciences of Dakar. She completed her training in Science to join the Zoology department of Professor C. Boisson, a specialist in ciliate and opaline protozoa. She was also an acquaintance of Claudine and Xavier Mattei who work on the morphology of spermatozoa. She is named assistant master. It was during this period that she published five articles on the embryonic development of Agama Agama. (Charnel 1963; 1965; 1966b; a; 1967), including one on the sensitivity of sex determination temperature for this species in 1966. This article has been cited more than 150 times since its release making it one of the most cited zoology articles published in the 1960s.

She left the University of Dakar, Senegal in 1968, having thanked some of the teachers in the wake of her independence. She abandoned her work on the Agama which constituted the subject of her thesis. Once in Nice, she worked in the group of Professor Jean Cachon in Villefranche-sur-Mer. It will also publish a scientific article on the ultrastructural morphology of a siphonophore parasite (Cachon et al., 1972).

Personal Life
She arrived in Africa at the end of 1945 to join her brother: first in Kaolack, Senegal, then in Cotonou, Dahomey (now the Republic of Benin), then again in Senegal, Dakar in 1949 or 1950. She divorced in 1953 and was first hired at the university library.
