Restoration work was carried out by T.G. Jackson during the years 1905–1912, including the famous saving of the building from total collapse. Some waterlogged foundations on the south and east walls were reinforced by a diver, William Walker , packing the foundations with more than 25,000 bags of concrete, 115,000 concrete blocks, and 900,000 bricks. Walker worked six hours a day from 1906 to 1912 in total darkness at depths up to 6 metres (20 ft), and is credited with saving the cathedral from total collapse. For his troubles he was awarded the MVO (Wiki) I've recently come into possession of two boxes of glass 'Magic Lantern' slides from the early 1900's. I'm slowly scanning and digitally restoring them.
