Children have always been particularly cherished subjects for photography. Portraits were made to preserve the memory of their stages of growth and, in an age when long-distance travel was rare, to share with faraway relatives. And, for a sadder reason: in 1840 an estimated one-third of children died before age five. Photography offered grieving parents the opportunity to immortalize their children’s features. This tragic genre of photographs, later called “post-mortems,” often depicts the children in fine clothing, laying down with eyes shut, as if merely napping.
