William Pengelly, a Devonshire geologist whose lifetime almost spanned the nineteenth century, pursued a very active life; his wide interests fitted him to make a very successful tutor and lecturer, while he did all he could to foster local education. His method of excavation of a newly discovered cave at Brixham gave credence, for the first time, to archaeological evidence from caves, and hence was instrumental in inducing English opinion to the view that man had existed at the same time as extinct fauna. Further excavation at Kent's Cavern - his major work - supplied additional evidence of the antiquity of man in such quantity that it could no longer be reasonably denied.
