Charles Dickens
From a daguerreotype by Mayall
c. 1853
John Hannavy, Research Professor in Art & Design, at the Bolton Institute (UK) has kindly written to share the following information: "Mayall did not arrive in Britain until 1846 or 1847, so the date [of the photograph] must be after that and some time before 1854. There exists a Mayall portrait of Kate Dickens taken in 1853, and it may not be too unrealistic to presume that they attended Mayall's studio together."
