Photogravure after a photograph of Svante August Arrhenius (1859-1927). Arrhenius researched over a wide range of subjects including immunology, cosmic physics and environmental issues. He discovered heat gain by the atmosphere due to carbon dioxide, and predicted the 'greenhouse' effect in 1896. His theory of ionic dissociation helped him to win the Nobel Prize for chemistry in 1903. From a collection of portraits of scientists published by Photographische Gesellschaft, Berlin, 1910. Dimensions: 460mm x 340mm.
