Wallsend Slipway and Engineering Co
From Graces Guide
The Wallsend Slipway and Engineering Company was formerly an independent company, located on the River Tyne at Point Pleasant, near Wallsend, Tyne and Wear, around a mile downstream from the Swan Hunter shipyard, with which it later merged.
1871 Public company formed. The company was registered on 2 October.  It was formed as The Wallsend Slipway Co in November by a group of Newcastle shipowners, and one shipbuilder, to repair the vessels of their respective fleets, hence the name 'Slipway'. Yard established by Charles Mitchell; named after two 300 foot slipways for the sole purpose of repairing ships. Charles S. Swan and his brother Henry F. Swan were two of the initial directors..
1873 First compound marine engines made. Then later, triple and quadruple expansion steam reciprocating engines were built.
1874 William Boyd, having left Thompson, Boyd and Co, was appointed managing director and it was Boyd who introduced marine engine building to the firm - this becoming over the next decade its most important activity - which brought the words 'Engineering' into the full title of the firm which then became The Wallsend Slipway and Engineering Co Ltd.
1878 Name changed. Managing Director William Boyd added & Engineering to the name of the Company.
