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.

The development of plasterboard (a sandwich of gypsum plaster between two sheets of paper) dates back to the late nineteenth century in the USA. The first patent was granted in 1894 but it was not until an American, Frank Culver, persuaded his new employer, Thomas McGhie and Sons, to buy a plasterboard plant from the USA that this new product was introduced to Britain. A site was acquired at Wallasey Cheshire and building started in 1916. However, McGhie's shareholders could not supply sufficient funding and in 1917 the plasterboard assets were sold to a new company, British Plaster Board Limited [BPB].
