(b Naples, Aug 25, 1829; d Portici, nr Naples, Feb 2, 1909). Italian composer and pianist. He studied the piano and composition in his native town, where he spent his entire life. His prolific output of fluently written, light and brilliant pieces (more than 400 works) won great success with the conventional middle class in Naples, which was culturally behind the times and inclined towards the flimsy, often frivolous genre of salon pieces: Acton's works became an indispensable part of the piano repertory of all daughters ‘of good family’ in Bourbon Naples. An amiable figure but of little distinction, he had no following of his own as a teacher, unlike his Neapolitan colleagues Costantino Palumbo and Alfonso Rendano.
