John Vaughan, known as Jacky, born in Worcester on "St Thomas' Day" in 1799, the son of Welsh parents. He worked his way up the iron industry, becoming an ironmaster and co-founder of the largest of all the Victorian iron and steel companies, Bolckow Vaughan. Where Henry Bolckow provided the investment and business expertise, Vaughan contributed technical knowledge, in a long-lasting and successful partnership that transformed Middlesbrough from a small town to the centre of ironmaking in Britain.
