Juan Crisostomo Jacobo de Arriaga y Balzola

Juan Crisóstomo Jacobo Antonio de Arriaga y Balzola was a Spanish Basque composer. He was nicknamed "the Spanish Mozart" after he died, because, like Wolfgang Amadeus Mozart, he was both a child prodigy and an accomplished composer who died young. They also shared the same first and second baptismal names; and they shared the same birthday (due to both having been born on the feast of St. John Chrysostom), 27 January (fifty years apart).
