This is a collection documenting the
history and production of stereographs by various publishers and photographers throughout
the United States, but especially in California. The items in the collection date from
approximately 1846-1940, when stereograph technology began to be replaced by moving images,
and depict a variety of extremely wide-ranging subjects, from the 1906 San Francisco
earthquake to the building of the Panama Canal. The West, as a landscape and a subject of
interest, is well documented here, as are views of California and Yosemite in particular.
Reflected here, too, are innovations in stereograph production technology, from door-to-door
salesmanship to the automated production techniques invented by H.C. White.
