After graduating, he attended the École nationale supérieure des beaux-arts de Lyon, where he studied with Claude Bonnefond.
Lavergne produced his first major work in 1853: a mural in the chapel of the Château de Châtillon-d'Azergues.
[3] Lavergne worked with Eugène Viollet-le-Duc as an architectural inspector, which enabled him to deepen his knowledge of stained glass and begin a new artistic career, creating a glass painting workshop that would be passed to his sons Georges and Noël.
For the Chapel of St. Augustine in Notre-Dame-des-Victoires, Paris, Lavergne did a beautiful stained glass window depicting Louis XIII consecrating France to Mary.
[6] Lavergne died at his home in Paris, shortly after his seventy-second birthday, and was interred at the Cemetery of Saint-Louis, Versailles.
