A spookily quiet Trafalgar Square at night, the imposing dome of St Paul’s against a dark sky and Big Ben, shrouded in thick fog. The landmarks are familiar to the modern eye, but these striking pictures, never published before, were taken in the capital almost a century ago. The images, from between 1910 and 1920, are part of a collection of 4,000 slides that have lain about, forgotten, in boxes in the archives of the London and Middlesex Archaeological Society. Once used for magic lantern shows at the Bishopsgate Institute, the images are now being published in a book called The Gentle Author’s London Album.
