—————————————————

“Anna Atkins (1799-1871) was the first person to bring together science, photography and publishing. The daughter of a distinguished chemist and zoologist, she began a photographic record of British algae in 1843. She used the cyanotype process, in which a sheet of paper coated with a solution of iron salts was exposed to sunlight in direct contact with a negative or, as her, a flat specimen. After exposure, the paper was washed in water, from which came the oxygen that produced the vivid blue (cyan) image that gives the process its name.” (CH)
