IAN JOHNSTON is a well-known authority on Clydeside shipbuilding and the historian of both John Brown’s and Beardmore’s. His training as a graphic designer is to be seen in the superb choice of photographs from the John Brown collection in Clydebank Battlecruisers and A Shipyard at War. This new book is a labour of love as Ian’s father worked for Thermotank, whose achievements he felt deserved wider public recognition.
