1811-1875. US inventor of domestic and industrial sewing machines. Within a few years of opening his first factory 1851, he became the world's largest manufacturer (despite charges of patent infringement by Elias Howe), and by the late 1860s more than 100,000 Singer sewing machines were in use in the USA alone. To make his machines available to the widest market, Singer became the first manufacturer to offer attractive hire-purchase terms.
