Harry Bertoia (1915 to 1978) was an Italian-born American sculptor, furniture designer and, late in life, a maker of sound. He emigrated to the United States in 1930, studied and taught at Cranbrook, and after the war designed for Knoll the wire chairs that made his name and funded his freedom to sculpt. From the 1960s he built his Sonambient sculptures: stands of tall metal rods that hum, ring and roar when struck or swayed, which he installed in a converted barn in Pennsylvania and recorded on a series of self-released albums.
