A Colourised Photograph of Sir Richard John Griffith (1784–1878)

Abstract: A colourised photographic portrait of Sir Richard John Griffith (1784–1878) dating from 1870 has been recently donated to the Geological Society of London. It shows the sitter in a typical pose surrounded by items of geological interest, including his Wollaston Medal and a geological map published in 1853. This is a rare and hitherto undocumented portrait of this important Irish public servant and geoscientist, and it and the various components depicted are described and discussed here.
