Henry Engelhard SteinwayBorn 15 Feb 1797; died 7 Feb 1871 at age 73.German-born American inventor of the overstrung iron-frame grand piano (1859). He began business in Germany, building his first piano in 1836. The Revolution of 1848 caused him to emigrate to America with his wife and sons where they continued innovating and building these instruments. Creating an iron frame design permitted greater string tension without the twisting and stability problems of wood, and he incorporated longer bass strings by orienting them obliquely over the others in his overstrung design. He exhibited this at the N.Y. Industrial Exhibition of 1855, taking first prize, leading to new prosperity. By 1856 he produced his first grand, and in 1862 the first upright. In 1864 he Anglicized his family to become known as Steinway.« |
