Nevil Story-Maskelyne (1823-1911) left law for the Natural Sciences in 1847, and was soon lecturing on mineralogy, a field he would come to lead. His research ran from the petrology of Stonehenge to developing the collection of minerals and meteorites at the British Museum into the 'largest and best arranged series ... in existence' (ODNB online). He and his wife Thereza May Llewelyn were both involved in the pioneering of photography. He was close friends of William Henry Fox Talbot (1800-77) -- whose own camera obscura is held at the Science Museum London.
