The brothers Goncourt’s celebrated quip chimes precisely with a much cherished image of the bewhiskered Victorian gent digesting the Times at the Reform or Athenaeum, before sorting out the world’s evils. But as Peter Clark, Britain’s leading urban historian, notes in a characteristically fact-packed but thoughtful study, that most English of institutions was going strong long before then.
