Career
In 1869 he received his diploma from the school of veterinary medicine in Lyon. In 1876 he was appointed professor of anatomy, physiology and zoology at the school of veterinary medicine in Toulouse. Toussaint is remembered for contributions made in the field of bacteriology.
From his research, he conducted important investigations of chicken cholera, septicemia and tuberculosis.
Probably his most significant contribution was the development of a method of vaccination against anthrax. However, cr for creation of the anthrax vaccine went to Louis Pasteur, following Pasteur"s celebrated demonstration with the vaccine on sheep at Pouilly-le-Fort in 1881.
At Pouilly-le-Fort, Pasteur used a vaccine attenuated by potassium dichromate, employing a process similar to Toussaint"s, who had published a means of attenuation by another antiseptic, carbolic acid. Pasteur never gave proper cr to Toussaint and his discovery.
Pasteur"s nephew, bacteriologist Adrien Loir (1862-1941) was aware of Toussaint"s work with the vaccine, of which he documented in the 1938 treatiseA l"ombre de Pasteur (In the Shadow of Pasteur).
From 1881, Toussaint was in declining health, reportedly from a nerve-related disease. He died on 3 August 1890 at the age of 43.
