Music publishing firm operated by Auguste O'Kelly in Paris between 1872 and 1888. He belonged to a family of French musicians of Irish origin which included the composers Joseph O'Kelly (1828–1885) and George O'Kelly (1831–1914) and as such has one sentence devoted to him in Joseph's biography in the 1881 supplement to Fétis' Biographie universelle des musiciens: "Un frère de cet artiste, M. A. O'Kelly, est éditeur de musique à Paris."
The Irish artist Aloysius O'Kelly who was studying in Paris in the early 1870s is NOT related to this family.
Auguste O'Kelly's firm operated under the brand name "Au Magasin de Musique du Conservatoire", a company founded in 1794 and originally an imprint for the Paris Conservatory. His predecessors included Célèste Cendrier ("Mme. Cendrier"), Edme Saint-Hilaire and Émile Cellerin. When he gave up in late 1888 his business and most of his catalogue were taken over by Mackar & Noël, later Albert Noël only (until 1910). He also had short-time partnerships with Ikelmer (1874 only), Rouget in Toulouse (1874–84), Lissarrague in Versailles (1877 only) and J. Naus in Paris (1880-1).
Auguste O'Kelly was born on 13 July 1829 in Boulogne-sur-mer and died in Paris on 16 February 1900. For further information see.
O'Kelly's plate numbers were issued in a regular chronological fashion. Plate numbers are in the format of A.O.K. or A.O'K. #### although some scores were published with no plate numbers and others using initials of the composers. In these cases the composers financed the print. A full overview of O'Kelly plate numbers is.
