Autographed Portrait of John Dalton as a young man
EDITORIAL USE ONLY: An autographed portrait of English chemist & physicist John Dalton (1766-1844) as a vigourous younger man. Dalton is best know for his work on the natural laws governing the behaviour of gases (Daltons's Law) and of his insights into the theory of atoms and their relative atomic weights. As he also had a colour vision condition and produced papers on the topic the term 'Daltonism' became synonymous with many forms of colour-blindness. Original held by the Manchester Literary & Philosophical Society.
