Juan Antonio Álvarez de Arenales (Reinoso, Spain, June 13, 1770 - Moraya, Bolivia, December 4, 1831) was an Argentine general of Spanish origin (considered also a Bolivian for his activities in Bolivia) that fought in the war for the United Provinces of the Río de la Plata, Chile and Peru.
In 1908 he formed the Cuarteto Villalón with Adolfo Colombo (tenor), Claudio García (baritone), Emilio Reinoso (mandolin), and Alberto Villalón (guitar).
Carlos Enzo Reinoso Valdenegro (born 7 March 1946) is a former Chilean footballer and manager.
Following the departure of Herrera, Reinoso played the first three games of the 2011 Apertura Tournament, until the arrival of the Argentine keeper Alejandro Sánchez against Palestino, Universidad Católica and Cobresal.
