Miller (1802-1856), a stonemason and self-taught geologist, wrote a number of essays and books on geology, society and education, including 'Scenes and Legends of the North of Scotland' (1835) and 'The Testimony of the Rocks' (published posthumously in 1857). His fossil collection of over 6000 specimens formed the basis of the Scottish national collection at the Royal Scottish Museum in Edinburgh. He was also a committed evangelical Christian and helped to found the Free Church of Scotland.
