Romain-Jean-François Hartmann, commonly known as Georges Hartmann (15 May 1843 – 22 April 1900) was a French music publisher, dramatist and opera librettist (publishing under the pen name Henri Grémont).
Born in Paris, he was the son of Jean Hartmann (1804–1880), a German national born in Neustadt, Bavaria, who acted as the French distributor for the music publisher B. Schott's Söhne. In 1868, Georges Hartmann became a music publisher, publishing, among others, works by
Georges Bizet,
Jules Massenet,
Édouard Lalo,
Benjamin Godard,
César Franck, and
Ernest Reyer. In May 1891, his publishing house failed and he was forced to sell it to Henri Heugel, the intermediary being Paul-Émile Chevalier, an employee of Hartmann's who was a nephew of Heugel. Through merger in 1980, Heugel itself became part of
Éditions Alphonse Leduc publishing empire.
