His father was Jean-Marie Jazet, verifier of the crown's buildings, who was mortally wounded in 1793 by an exploding cannon whilst serving in the Paris National Guard, when Jean-Pierre-Marie was only five.
Later, still faithful to his master, he accompanied him until his death - Debucourt, who could no longer work, had spent considerable sums and his nephew helped him to end his life peacefully.
[1] He began his peak period two years later with engravings after Jacques-Louis-David's The Coronation of Napoleon, Antoine-Jean Gros's Standing Portrait of général Lassalle, Horace Vernet's The Bivouac of Colonel Moncey and François-Joseph Heim's Distribution of Prizes at the 1824 Salon.
His many engravings, particularly those realised after Vernet's works and on subjects from Napoleon I's life and the First French Empire, then his regular exhibiting at the Paris Salon gained him a major reputation.
[3][4] To sell prints drawn from matrices which formed his oeuvre and to keep up and expand his presence in the art market, Jazet was mainly his own editor, working from 71 fauborg Saint-Martin then 7 rue de Lancry.
