1802–1885
A prolific figure of 19th-century French popular theater, he wrote plays, librettos, songs, and verse that moved easily between the stage and the salon. His work is especially tied to vaudeville and to the music of his wife, the composer Loïsa Puget.

Born in 1802 and died in 1885, Gustave Lemoine was a French playwright and songwriter whose name appears across a large body of 19th-century dramatic and musical works. Library and reference sources consistently describe him as a dramatist, lyricist, and man of letters, and surviving catalogs show just how active he was over many decades.
He is particularly remembered for writing for the theater and for collaborating on songs and stage works that fit the lively, conversational style of French vaudeville. Several sources also connect him closely with the composer Loïsa Puget, whom he married; he wrote many romances for her and is associated with works created for performance in salons as well as on stage.
Although he is far less widely known today than some of his collaborators, Lemoine’s career offers a vivid glimpse of everyday literary and musical culture in 19th-century France: practical, prolific, and closely linked to performance. I couldn’t confirm a suitable portrait image from the sources I checked, so I’ve left that out rather than guess.
