Scope and Content
Sixteen daguerreotypes and ambrotypes (early photographs), most of them portraits.
Background
Daguerreotypes, generally dating from 1840-1855, are photographs made on polished silver without any emulsion. Ambrotypes, chiefly 1855-1865, are photographs on glass coated with an emulsion. Both daguerreotypes and ambrotypes are mounted in cases, daguerreotypes because of the need to seal the silver against tarnish and ambrotypes because of the fragility of glass and the need to make what are really negative images appear positive by putting a black backing behind them.
