Aerial Photographs of the 1906 Earthquake
hansoloaf writes "In 1906 San Francisco had a devastating earthquake - registering around 7.7 to 8.3 on the Richter scale. George Lawrence had devised ways to take aerial photographs and went to SF to showcase his technology. He used kites and custom built cameras that could take photos while up in the air."
