Germany attacked London 71 times between September 1940 and May 1941 in a bombing campaign known as the Blitz. Over 1.4 million Londoners were left homeless from the destruction. An exhibition at Galerie Daniel Blau from May 30 to June 29, 2013 featured vintage photographs from the Blitz documenting the damage and civilians salvaging possessions from bombed buildings and seeking shelter in underground stations while wearing gas masks. The exhibition aimed to increase awareness of London's experience with destruction and mass displacement during WWII as fewer remain who remember the Blitz firsthand.
