[3] He made portraits of Francoise Guizot, Alexandre Dumas, Jules Janin, Théophile Gautier, Gioachino Rossini, Eugène Scribe, Émile Augier, and Thomas Philippon, François Certain de Canrobert, and the Polish patriot Adam Czartoryski,[4] several of whom were also portrayed by Fauchery's friend, photographer Nadar (Gaspard-Félix Tournachon), with whom in 1848 he journeyed with a group of idealistic French and Polish émigrés who were intent on liberating Poland from Russia.

[2] Fauchery returned to UK/Europe in 1856 on the Roxburg Castle, but missed the successful staging of a play he wrote with Théodore Barrière, Calino, charge d'atelier,[8] at the Vaudeville Theatre in Paris.
