Born in Voreppe, Isère, into a farming family, Jean Alexis Achard was self-taught and started his career as a clerk for a lawyer.
In 1846, he attended the Barbizon School and became friends with the painters Jean-Baptiste-Camille Corot, Théodore Rousseau, Charles-François Daubigny and Narcisse Virgilio Díaz, on whom he had a certain influence and who taught him to paint in the pattern of the Paris region.
[2] He is the creator of the École dauphinoise, whose notable members were Laurent Guétal, Ernest Victor Hareux, Charles Bertier and a few others.
But after his comeback in Grenoble, his influence was considerable, especially on Laurent Guétal, Charles Bertier and Édouard Brun, who eagerly followed his advice.
He was a teacher and an adviser for the generation of young Dauphiné painters in Proveysieux, including Théodore Ravanat, Jacques Gay, Henri Blanc-Fontaine.
