Charles Macintosh (1839–1922), known as 'the Perthshire Naturalist', was a musician and self-taught amateur naturalist from Inver, near Dunkeld, Perthshire, Scotland. He, with his younger brother James, who was a fiddler and himself a composer, represented the third generation of an important musical family in the area. Their grandfather James (1791-1876) had learned fiddle from Niel Gow, who also lived in Inver.
