    Description
    Half-length portrait of John Dollond, seated at a table, wearing a brown coat, white shirt and cravat. On the table is a volume with ‘Opticks’ [denoting Sir Isaac Newton’s work] written on the top edge, and a small brass-boxed lens resting on top of it. Dollond holds a similar, smaller lens in his left hand.

    Inscribed: ‘B. Wilson pinx.t J. R. Smith Sculp.t/ John Dollond, F. R. S./ Who in the Year 1758 invented the ACHROMATIC TELESCOPE, by discovering the difference in the dispersion of the Colours of Light, when the mean rays are equally refracted by the different mediums: An important addition to the SCIENCE OF OPTICKS, which had been despaired of by the greatest Philosophers in Europe/ He died 30th November in the 55th Year of his Age.’

    John Dollond (1706-1761), British optician, was elected a Fellow of the Royal Society in 1761.
