Carte de visite photograph by H J Whitlock of William Pengelly (1812-1894). Pengelly began his career as a school teacher but his interest in mathematics and natural science led him to pursue a career in geology. He was a popular lecturer throughout Britain but is probably best known for his geological study of Devonshire. His excavation of several caves in the area helped to establish that man had existed at the same time as extinct fauna. In 1862 he founded the Devonshire Asociation for the advancement of science, literature and art. He was elected a fellow of the Geological Society in 1850, and a fellow of the Royal Society in 1863.
