Autochrome photo of J. Norman Collie

This autochrome image, produced around 1910, shows J. Norman Collie, who was professor of chemistry at UCL and pioneer of research into the noble gases as well as being an accomplished mountaineer.


The tube in front of him contains excited neon, which is glowing in that gas' distinctive shade of red.


The photo was taken using the Lumiere Autochrome process, an early colour photography process that relied on particles of coloured starch deposited on the photographic plate acting as filters.
