A Biographical Dictionary of 19th Century Photographers in South and South-East Asia
Medical officer with T.D. Forsyth's expedition to Yharkand in 1870. Photographer, and joint author with Allan O. Home, of Lahore to Yarkund. Incidents of the route and natural history of the countries traversed by the expedition of 1870 under T.D. Forsyth Esq C.B. (1873). This book was illustrated with heliotypes from photographs by Henderson: ‘The plates...give a truthful representation of the places, without leaving any margin for the imagination of the artist; all these plates are done by the new heliotype process, from negatives which were never very good, and which suffered greatly by the rough treatment they were subjected to during the march.’ All the images in the book are reversed because the plates were varnished for protection.
Also author of Catalogue of plants in the Royal Botanic Gardens, Calcutta (1873).
