James StarleyBorn 21 Apr 1830; died 17 Jun 1881 at age 51.British inventor and manufacturer, known as the father of the bicycle industry. Starley left the family farm as a teenager and after initially working as a gardener, he turned to mechanical interests. He improved the early sewing machine, and by about 1861, was in business with Josiah Turner as the Coventry Sewing Machine Company. Within a few years, their factory began producing bicycles. In 1870, he went into business for himself, producing his Europa sewing machines and Ariel bicycles, "penny-farthing" and tricycles. The Ariel, a lightweight all-metal bicycle (1871), is regarded as the first true bicycle, the first self-propelled two-wheeler to use pivot-center steering. His tangent-tension spoke wheel (1876) is still used.« |
