Gateshead during the First World War The photographs were taken by Sir W G Armstrong Whitworth Co Ltd who built the factory The images date from June 1916 shortly after the factory became operational What makes the factory and these photographs of it so special is that all the management and workers there were Belgian The factory and the nearby village of Elisabethville built to accommodate them were like a little corner of Belgium transplanted to the North East of England More information about the factory and the village of Elisabethville can be found in the blog which accompanies this set

Point on 28 October It focuses in particular on life along the foreshore at South Shields during the 1950s but also includes a few images from further down the coast South Shields has long been a popular seaside resort and also has a proud industrial heritage Times have changed though and many of the old industries such as shipbuilding and coal mining have disappeared Rather than stand still and accept this change in fortunes South Tyneside Council is pressing ahead with an ambitious vision to transform the Foreshore Town Centre and Riverside areas into vibrant destinations Haven Point is a key part of this change Tyne Wear Archives and South Tyneside Local Studies Library have a vital role to play in this As South Shields is regenerated and forever changed the Archives and Local Studies serve as its memory We keep alive a window into the town s past preserving the history of people places and industries that no longer exist South Shields must look forward but its sense of direction will be lost if it forgets where it came from These images together with a fantastic selection from South Tyneside Local Studies Library can be seen in a digital exhibition at Haven Point

Shoe-Black From Street Life in London 1877 by John Thomson and Adolphe Smith The independent boot black whose photograph is before the reader found by experience that the system instituted was not altogether pleasant He has served in two brigades the blues and the reds and found them both equally objectionable so at last he gave up the uniform and became an independent boot black In this capacity though free he experienced all the persecutions to which I have alluded and as he grew older and more tired of this life he finally resolved to leave the narrow streets for the broader thoroughfares of the ocean As a sailor he promises to become a useful help to his captain and ship His mother has to nurse an invalid husband and must also provide for a large family Under these circumstances it was not always easy for her to spare the services of her son But when he became an independent boot black he could go out at his own hours and thus was of greater use to his mother in her trouble and it was a great help to the family to know that whenever the boy had a few moments to spare he might run out and hope to gain some pence by cleaning gentlemen s boots For the full story
