(bapt. Burgdorf, 18 Jan. 1733; d London, 14 Apr. 1794). Swiss-born painter (mainly in watercolour) and draughtsman, who settled in England in 1768. He was a prolific topographical draughtsman, much of his work being done on commission for antiquarian patrons. Most notably he made drawings for The Natural History and Antiquities of Selborne (1789) by Gilbert White. Grimm also made caricatures and drawings of Shakespearian subjects, and himself wrote poetry. His work is well represented in the British Museum and the Victoria and Albert Museum.
