Césaire Phisalix (8 October 1852, Mouthier-Haute-Pierre – 16 March 1906) was a French physician and biologist. He was the husband of Marie Picot Phisalix (1861–1946), an expert on venoms and venomous animals.Le Musee Pasteur Césaire et Marie PHISALIX, deux chercheurs comtois

He studied sciences at the Catholic college in Besançon and medicine in Paris, earning his medical doctorate in 1877. Later, he continued his studies at the military school in Val de Grâce with Alphonse Laveran, a future winner of the Nobel Prize in Physiology or Medicine. In 1886, he was named deputy professor of zoology at the school of medicine and pharmacy in Besançon, and in 1888 was appointed director of travaux de zoologie at the faculty of Besançon.Césaire PHISALIX (1852-1906) - Racines Comtoises (biography) Shortly afterwards, he returned to Paris, where he served as a lecturer at the Muséum national d'histoire naturelle.

Along with biochemist Gabriel Bertrand, Phisalix isolated the psychedelic drug bufotenin in 1893, though its hallucinogenic effects were not discovered until much later. In 1894, also with Bertrand, he developed an antivenom for treatment against snake bites. For his research on venom and venomous animals, he was awarded the Prix Montyon in 1894 and the Prix Bréant in 1898 and was created a Chevalier of the Legion of Honour in 1900.Google Books Animaux venimeus el venins: la fonetion venimense chez tous les ..., Volume 1
