On November 8, 1939, swiss clock-maker George Elser attempted to assassinate Adolf Hitler at Munich's Bürgerbräukeller Hall with a time bomb. Prompted, however, either by knowledge of the plot or by his legendary sixth sense, Hitler left the building 7 minutes before the bomb exploded. Elser was arrested by border police 100 yards from the Swiss-German border and spent the next six and a half years in a concentration camp. He was executed by the SS only two weeks before V-E Day.
