Marqueste's virtuosic work, often combining two figures, tended to be executed by specialist carvers working by pointing up his models, as had become common studio practice among French sculptors in the later nineteenth century.
Among his commissions are a large number of allegorical architectural figural sculptures, historical portraits (Victor Hugo, and Geographie for the Sorbonne, 1901) and others for the monumental Gare d'Orsay (now the Musée d'Orsay), the Beaux-Arts de Paris, the Grand Palais for the 1900 Exposition, and the Hôtel Dufayel, Avenue des Champs-Élysées (1906, demolished), which was very much criticised; as well as monuments for North[3] and South America. He was also the author of portrait busts and statues of Victor Hugo, Léo Delibes, Ferdinand Fabre and a large output of classical subjects. He gained the Grand Prix at the Paris Exposition Universelle of 1900.
He taught at Beaux-Arts de Paris, where his notable students included Fanny Rozet.[4][5]
His portrait bust, sculpted by Ernest Henri Dubois, is at the Musée des Augustins, Toulouse, which also has a considerable series of statuettes and maquettes, or sculptural sketches.[6] His papers are conserved at the historical department of the Archives Nationales.[7]
