Albert Lawrence "Larry" Luther (1895-1966) was a powerhouse operator for Southern California Edison Co. (SCE), a utility company that in 1917 merged with Pacific Light and Power Corporation. The centerpiece of the merger transferred ownership of the Big Creek hydroelectric project to SCE. Big Creek eventually became one of the world's largest hydroelectric projects. Luther's photograph album is from his time working for Southern California Edison Co. during the Big Creek hydroelectric project between 1917 and 1920. The images depict work and leisure, with captions written by Luther between 1917 and 1920.
