Avant-printemps, Op.96

Louis Charles Félix François Gregh (16 March 1843 – 21 January 1915) was a French composer and music publisher.

Gregh was born in Philippeville, now Skikda, Algeria. His family was of Maltese origin. As a composer, he wrote operettas, ballets, numerous popular songs, and over 150 works for piano for two, four, and six hands. He died in Sainte Mesme, Seine-et-Oise, now Yvelines, aged 71.

His son Fernand Gregh (1873–1960) was a philosopher, literary critic and poet, member of the Académie française.

Gregh registered as a music publisher with SACEM in February 1873 after having bought the catalogue of the Parisian publisher Claude Heu. He grew by acquiring, by auction, parts of the dissolved publishers Léon Escudier (1882), Egrot (1884), and Jochem (1899). He was also the French representative of the publishers Litolff and Universal Edition. His business was quite successful, and he only gave up in old age in 1907, when he sold it to Rouart, which in turn was taken over by Salabert in 1953.
