After a brief period of schooling, Gillott began working in the cutlery trade in his home town of Sheffield. In 1821 he moved to Birmingham, where he found employment in the steel toy trade, the technical name for the manufacture of steel buckles, chains and light ornamental steel-work generally.[2]
About 1830 he turned his attention to the manufacture of steel dip pens by machinery.[2]His company rapidly became successful and Gillott was soon a very wealthy man. It was rumoured locally that he buried some of his money in his cellar so that it did not become known that he had acquired so much. He certainly spread his cash across a number of bank accounts in Birmingham. In 1840 he opened his Victoria Works; the business employed mainly girls. Gillott also invested in the new railway companies and especially in property and land – not only in Birmingham, where he bought a large estate in Edgbaston, but also in London and Wales. The family home for many years was "The Grove" on Westbourne Road in Edgbaston.
Gillott was an often secretive man, both in business and in art collecting. He socialised with a small group of friends at the Hen and Chickens Hotel and the Theatre Royal (which he part-owned) in New Street, Birmingham.[3]
In later years, Gillott's son, Joseph Gillott junior, purchased a considerable estate in the village of Catherine-de-Barnes, Solihull on which he built New Berry Hall, a large gothic mansion with North and South Lodges. He also built the school in the village.
A collection of Gillott's letters are held at the Cadbury Research Library, University of Birmingham.[7]
