Oscar Gustave Rejlander (Stockholm, 19 October 1813 – Clapham, London, 18 January 1875) was a pioneering Victorian art photographer and an expert in photomontage. His collaboration with Charles Darwin on The Expression of the Emotions in Man and Animals has assured him a position in the history of behavioural science and psychiatry. Biography According to his naturalisation papers, Rejlander was born in Stockholm on 19 October 1813. He was the son of Carl Gustaf Rejlander, a stonemason and Swedish Army Officer. During his youth, his family moved to the Swedish-speaking community in Rauma, Grand Duchy of Finland (then part of Russia). In the 1830s, he relocated to England, initially settling in Lincoln, England. In the 1850s he abandoned his original profession as a painter and portrait miniaturist, apparently after seeing how well a photograph captured the fold of a sleeve. He set up as a portraitist in the industrial Midlands town of Wolverhampton, probably around 1846. In the early 1850s he learned the wet-collodion and waxed-paper processes at great speed with Nicholas Henneman in London, and then changed his business to that of a photography studio. He undertook genre work and portraiture. Rejlander also produced nude studies, mainly for use as studies by painters, and later revealed that his early work was made with the aid of a local troupe of theatrical performers. Rejlander undertook many experiments to perfect his photography, including combination printing, which he did not invent; however, he created more elaborate and convincing composite photographs than any prior photographer. He had articles feature in the Wolverhampton Chronicle newspaper, on 15 November 1854 an article called "Improvement in Calotypes, by Mr. O.G. Rejlander, of Wolverhampton" it suggests that by 1854 he was experimenting with combination printing from several negatives. He was a friend of photographer Charles Lutwidge Dodgson (better known by the pen name Lewis Carroll), who collected Rejlander's work and corresponded with him on technical matters. Rejlander later created one of the best known and most revealing portraits of Dodgson. Like Dodgson, Rejlander's work included many pictures of "undraped" children: "The remarks of his contemporaries bear witness to both his attainments and to the influence which he exercised. Some of his critics were exuberant. Thus one speaks of his undraped children as being as 'beautiful as those of Della Robbia, Flamingo, and Raphael.' Mr. H.
