Caption: Portrait of the British chemist and photography pioneer Thomas Wedgwood (1771-1805). It had long been known that nitrate and chloride of silver were affected by light. Wedgwood was the first to realise that the chemical properties of silver salts could be used to obtain pictures. In 1802 he published in the Journal of the Royal Institution of Great Britain how a silhouette of any object could be obtained by projecting its shadow on a piece of paper previously moistened with nitrate of silver. Wedgwood aimed at obtaining photographs with the camera obscura but his experiments were unsuccessful. He was a member of the Wedgwood family well known for pottery manufacture.
