Francisco José Debali was a Hungarian-born composer who emigrated to Uruguay in 1838. He authored the national anthem of Uruguay and, possibly, the tune to Paraguayos, República o Muerte, which became the Paraguayan anthem.
In 1845 he composed what would be adopted three years later as the Uruguayan national anthem, to a text by Francisco Acuña de Figueroa. It was played for the first time in public on July 19, 1845. Fernando Quijano, his assistant, who had submitted the composition to the government's selecting contest, was credited with the authorship because of Debali's failure to grasp the content, in the Spanish language, of the governmental decree that adopted his composition as the country's anthem.
