Jean Joseph Henri Toussaint

Jean Joseph Henri Toussaint (30 April 1847 – 3 August 1890) was a French veterinarian born in Rouvres-la-Chétive, department of Vosges.

In 1876 he was appointed professor of anatomy, physiology and zoology at the veterinary school of Toulouse.

From his research, he conducted important investigations of chicken cholera,[1] sepsis, and tuberculosis.

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 credit to Toussaint and his discovery.
