Juan Crisóstomo Jacobo Antonio de Arriaga y Balzola (January 27, 1806 – January 17, 1826) was a Spanish 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, January 27 (fifty years apart).
