Sometime in the summer of 1942, the economists John Maynard Keynes and Friedrich Hayek spent the night on the roof of the King’s College Chapel in Cambridge. The Germans were in the midst of what some called the “Baedeker bombings,” a campaign to destroy the quaint and historical sorts of buildings that might be found in a Baedeker travel guide, in an effort to break the British fighting spirit. The Cambridge faculty volunteered to spend nights protecting their buildings from damage by extinguishing flames from incendiary bombs. Keynes was a long-time fellow of King’s College. Hayek was in Cambridge for the summer, the London School of Economics having closed due to the blitz.
