Born in Cortaillod, Persoz studied physical science in Paris under Louis Jacques Thénard and received his doctorate in 1833.

Persoz was a professor of chemistry at the University of Strasbourg since 1833 and then a professor of dyeing and calico-printing at the Conservatoire des Arts et Metiers since 1852.^[2]

His work on diastase, also known as amylase, was carried out in collaboration with Anselme Payen and published in 1833.^[3] His work on dextrin was carried out in collaboration with J.B. Biot^[4]
