SINCE 1900 "Publisher and store of music, pianos, harmoniums and other instruments and music accessories" The origins of Unión Musical Española can be traced back to Bilbao, the city where Louis Ernest Dotesio founded a music publishing and instrument sales company in the last decades of the nineteenth century. In 1898 he acquired the funds of the largest Spanish music publishing company, Casa Romero, and in 1900 he merged both properties into a single one called Casa Dotesio, Sociedad Anónima, which would soon enjoy notable prestige and would settle in several Spanish capitals, Madrid among them. After the subsequent acquisition of a multitude of music publishers from all parts of the country, the name of the society would evolve into Unión Musical Española in 1914, with its headquarters in Madrid, in Carrera de San Jerónimo and branches in other provinces.
