A Pivotal Bus Ride
In July 1940, when Ludwig and Margit von Mises made their way by bus from Switzerland across German-occupied France , the bus driver had to proceed very carefully and make many detours via back roads to avoid German checkpoints. If you would like to play with a fascinating exercise in counterfactual history, imagine how history would have gone had the Germans arrested Mises and his wife, placed them in indefinite detention, and perhaps ended up killing them in some horrible concentration camp.
