[1] As a child, Mozin received music lessons from his father Benoit Mozin (1769–1857), a pupil of François-Joseph Gossec, who had composed several piano works himself and had taught piano at the Conservatoire de Paris since its foundation in 1795.
Mozin completed his studies at the Conservatoire, where he studied counterpoint with Fromental Halévy, composition with Ferdinando Paër and Jean-François Lesueur, harmony with Victor Dourlen and piano with Pierre Zimmermann.
After attending the composition classes of Halévy and Henri Montan Berton, he entered the Prix de Rome competition in 1841 and won the Second Grand Prix with the setting of the poem Lionel Foscari by Amédée-David de Pastoret.
[clarification needed] On 18 February 1843, he married Marie Rose Adéone Fossé in Paris.
His vault decorated with a portrait by Antoine Étex (a family friend) was vandalized and the marble medallion representing him was stolen.
