Whiteboard
Albert Stallion invented whiteboards while working at Alliance in the 1960s. Alliance (now known as PolyVision) produced enameled steel for architectural cladding, but Stallion noted it could also potentially be used as a writing surface. Stallion later left Alliance to form his own whiteboard production company, MagiBoards.
Whiteford Lighthouse
The first known cast-iron British lighthouse was at Swansea Harbour and was built in 1803. The architect was Jernegan, and the plates were cast at the Neath Abbey Ironworks.
