Joseph Cliff (1806-1879) founded a brick works at Wortley and owned Micklefield Colliery near Leeds with his four sons. After Rowland Winn persuaded him to try his hand at mining ironstone, Cliff built the furnaces of the Frodingham Iron Company, producing iron from May 1865 charging it with coke from another of his business interests at Penistone. Frodingham was the most successful of the six original ironworks and the first to make steel in 1890.

His second son, also Joseph (1841-1914), was appointed manager of the Frodingham Ironworks in 1866 aged just 25.
