"Thereza Dillwyn Llewelyn with Her Microscope" by John Dillwyn Llewelyn (British, Swansea, Wales 1810-1882). Photograph from 1854. Salted paper print from glass negative. The border of Llewelyn's image is a photogram of ferns, a clever variation on the decorative borders of lace, cut paper, or ink and watercolor that embellished many nineteenth-century albums. In the central vignette we see the photographer's daughter Thereza (1834-1926), with her books, botanical specimens, and scientific apparatus.
