1914 Lubin vault fire
On the morning of June 13, 1914, a disastrous fire and a series of related explosions occurred in the main film vault of the Lubin Manufacturing Company in Philadelphia, Pennsylvania. Several possible causes for the blaze were cited at the time, one being "spontaneous combustion" of highly flammable nitrate film, which was the motion picture industry's standard medium for cameras throughout the silent era and for the first two decades of "talking pictures".
