The Fine Arts Museums of San Francisco is home to a unique collection of 167 film negatives taken by photographer Arnold Genthe chronicling the aftermath of the 1906 earthquake and fires. The negatives were acquired by the Legion of Honor in 1943.
On the day of the earthquake Genthe, an established photographer best known for his society portraits and views of old Chinatown, took to the streets of San Francisco equipped with a handheld Kodak camera and pockets full of roll film.
The film Genthe used was composed of a gelatin silver emulsion on a thin plastic support of cellulose nitrate. Cellulose nitrate film was introduced commercially at the end of the nineteenth century and remained in use until the mid-twentieth century. Lightweight, transparent and flexible, cellulose nitrate film freed photographers from the inconveniences of its predecessors, paper and glass plate negatives.
