Qualified in medicine at the London Hospital and became a naval surgeon. He saw active service in the Boer War and in the 1914-18 War, taking part in the Battle of the Falkland Islands in H.M.S. Cornwall, and in the East African campaign. At the end of the War he was posted to the Admiralty, but not being particularly interested in administration he retired about 1920, with the rank of Surgeon Commander, to devote his life to entomology. He went to the Indian Forestry Research Institute at Dehra Dun, but after two years he was invalided to Switzerland with a suspected lung infection.
