This is why British scientist who produced first photographic book has been given a Google Doodle

An9Today marks the birthday of Anna Atkins, a British botanist whose use of cyanotypes – or ‘sunprints’ – of plants and algae in botanical studies paved the way for the use of photography in scientific publishing.

Now versions of her beautiful photographic images are being used as a Google doodle to celebrate the 216th anniversary of her birth, in 1799. The delicate leaves used to spell out the name of the search engine are slate blue against a darker blue background. This is due to the cyanotype process, which involves the exposure of a mix of ammonium iron citrate and potassium ferricyanide to ultraviolet light, leaving the paper so-called Prussian blue.

In fact, the word ‘blueprint’ comes from the same process, which had previously been used to reproduce architectural drawings and designs. Atkins’ claim to fame rests on her realisation that the photographic process could be used to give accurate and detailed botanical images, thus advancing the possibility of scientific illustration. She did this by placing leaves directly on the paper for the length of the exposure, which makes these, strictly speaking, photograms, rather than photographs.
