Charles-Émile-Hippolyte Lecomte-Vernet (1821-1900) was the son of Hippolyte Lecomte (Carle Vernet's son-in-law). He studied at the Ecole des Beaux-Arts under his uncle, Horace Vernet, and Léon Cogniet. He made his Salon debut in 1845, and won a third-class medal in 1846. He painted decorative murals for the church of St-Louis-en-l'Île and for the Palais de Justice, Paris.

Isidore Brasseur (c.1806-92) was the French tutor to Prince Albert Edward. He was Professor of French Literature at King's College, London, the author of a grammar of the French language, published in 1840, and of a book of exercises in French phraseology (see RCIN 1129190). He is shown here wearing a dark suit with a white shirt, and a blue tie with a ship's wheel motif; there is a small red bow on his lapel.
