Hans Renold (31 July 1852 - 2 May 1943) was a Swiss/British engineer, inventor and industrialist in Britain, who founded the Renold manufacturing textile-chain making business in 1879, and with Alexander Hamilton Church is credited for introducing scientific management also known as Taylorism to England.
In 1879, with £300 borrowed from his prospective father-in-law, Renold purchased a small textile-chain making business in Salford, Lancashire, from James Slater and started the Hans Renold business.
Hans Renold and his first wife Mary Susan Herford (1855-1919), were married in 1880, and had six children: Mary Katharine Renold, Charles Garonne Renold, Amy Madeleine Renold, Mary Robberds Renold (died young), Hans Herford Renold (died young) and Austen Hugh Renold. He married Rowena Hague Pigott (1874-1962) in 1923.

Soon after starting the business in 1879, in 1880 Hans Renold invented the bush roller chain. This represented a great advance on the common pin-and-link chains of the day and laid the design foundation upon which all modern precision roller chains are based. The firm immediately extended its business from textile chains into cycle chains for the new safety bicycle invented by J. K. Starley.
Renold was not only a brilliant engineer and a model employer who built around him a very skilled labour force, but was also a very astute businessman. His business prospered and he steadily ploughed back his growing profits into premises and plant. He moved the business to Brook Street, Manchester in 1881. In 1889 a rapid expansion of the business took place and a new factory, Progress Works, was built in Brook Street. In 1906, Hans Renold planned and started construction of Renold Works on open land at Burnage, five miles to the south of Manchester.
Renold had long been devoted to the ideal of establishing a firm sense of community among his employees and their families and in 1909 gave his active support to the establishment of the Hans Renold Social Union for the encouragement of a wide range of leisure activities.
Hans Renold Limited was formed as a private limited company in 1903. It merged with The Coventry Chain Company Limited and was registered as a public limited company named Renold and Coventry Chain Company Limited in 1930. It was renamed Renold Ltd. in 1967, and later became Renold PLC. Nowadays the company still bears his name.
