Eldest of G.R.Waterhouse’s three sons and a godson of Charles Darwin and Sir Richard Owen. Born at Bloomsbury and lived from the age of 9 in his father’s residence in the British Museum. Educated at University College School and King’s College. Joined the staff of the Museum as a Junior Assistant in the Entomological Department on 9 July 1866. Promoted to First-Class Assistant 5 April 1879 and Assistant Keeper 10 April 1905 remaining in office until his retirement on 30 June 1910. He then stayed on at the Museum to complete the re-arrangement of the Buprestidae, including the incorporation of the Kerremans Collection, which he had nearly finished at the time of his death. (More precise details of the families he re-arranged and the dates are given in Waterhouse et.al.(1906) p.554-555). Waterhouse’s role involved preparing the Museum displays and making models as well as research work on the collections. Published more than 230 papers on Coleoptera, which were his favourite group many describing new genera and species from all over the world. The first, a note of his discovery of a specimen of Hynobius perrisii, recently introduced to England by Rye, in his father’s collection, appeared in EMM., 1, 1864, p.138, and the second, in the same periodical, p. 278, introduced Gonioctena affinis to Britain, found amongst some specimens taken by Mr Cocking of Norfolk. Perhaps his two most important publications were the volumes on Lycidae and Buprestidae (a favourite group) in the Biologia Centrali-Americana series. In later years he became interested in Hymenoptera Mymaridae on which he wrote a number of articles. Of his publications other than those on Coleoptera the best known is the two volume The History of the Collections contained in the Natural History Departments of the British Museum, (1906). There is material related to him in David Sharp’s scrapbook and autograph album in the RESL (Pedersen (2002) p.49) and an obituary in EMM 53, 1917, 67-68 which includes a portrait (opp. p.49).
