Intimately detailed, non-fiction accounts of the horrors of British cities proliferated in the mid-1800s, casting critical light on the slums. New sanitation laws were passed and philanthropic interventions were staged, but they barely made a dent in the problem. Then, in 1871, the utopian science-fiction novel exploded onto the scene, offering radical imaginary solutions to the seemingly intractable problems of industrial urban life. Edward Bulwer-Lytton’s The Coming Race offered readers a vision of tidy garden villages built by a highly advanced branch of humanity who have rejected cities. A Dutch author imagined a radiantly futuristic, enormous, dense, bustling London and was rejected by English-speaking critics, while other British writers developed the more popular theme of dispersal in different ways, always with imaginary mechanized transport at the ready to facilitate life amid the cottages, villas, and towers of the glassy, metallic garden future. Increasingly, they also turned to catastrophic urban destruction as the solution to London.
