Thomas Lewis (died 1764) was one of the founders of the Dowlais Ironworks, one of the largest ironworks in Wales.


Born into a landed family from Llanishen, Thomas Lewis became an iron-master.[1] He already owned the Pentyrch blast furnace and several small forges when he became a partner in Dowlais Ironworks in 1759.[2] Lewis was the partner who arranged the mineral leases and construction of the new ironworks: the works were carried out by his business, Thomas Lewis & Co.[2] He headed the business and his family interest was not bought out until 1848.[2]

He was also a partner in the firm of Coles, Lewis & Co which had interests at Melin-y-cwrt and Ynys-y-gerwn.[3]

Lewis's family had lived at Llanishen for many generations but he was responsible for building the New House there.[4] He was clearly a highly respected individual and served as High Sheriff of Glamorgan in 1757.[5]

He died in 1764.[6]
