Anna Atkins (maiden name Anna Children) (16 March 1799 – 9 June 1871) was an English botanist and photographer. She is often considered the first person to publish a book illustrated with photographic images. Some sources claim that she was the first woman to create a photograph.
Sir John Herschel, a friend of Atkins and Children, invented the cyanotype photographic process in 1842. Within a year, Atkins applied the process to algae (specifically, seaweed) by making cyanotype photograms that were contact printed “by placing the unmounted dried-algae original directly on the cyanotype paper”.
