( b. 1846; d. 26 Aug 1913 )
was an ophthalmic surgeon by profession, whose spare time interests included photography. He made his own camera equipment, and enthusiastically promoted the use of photography in geology. Whilst working as a lecturer on volcanoes, he took many photographs of glaciers and mountains, some of which gained awards. One of his concerns, evident in his work, was for human suffering arising from volcanic and other disasters. His photographic collection is calculated to be more than 3000 images, many of which were taken on his travels. Some of his selected work is stored in the Yorkshire Museum.
