Hampson studied at Charterhouse School and Exeter College, Oxford. He travelled to India to become a tea-planter in the Nilgiri Hills of the Madras presidency (now Tamil Nadu), where he became interested in moths and butterflies. When he returned to England he became a voluntary worker at the Natural History Museum, where he wrote The Lepidoptera of the Nilgiri District (1891) and The Lepidoptera Heterocera of Ceylon (1893) as parts 8 and 9 of Illustrations of Typical Specimens of Lepidoptera Heterocera of the British Museum. He then commenced work on The Fauna of British India, Including Ceylon and Burma. Moths (4 vols 1892-1896).
Albert C. L. G. Günther offered him a position as Assistant at the Museum in March 1895, and after he succeeded to his baronetcy in 1896, he was promoted to acting Assistant Keeper in 1901. He then worked on a Catalogue of the Lepidoptera Phalaenae in the British Museum (15 vols, 1898–1920).
He was married to Minnie Frances Clark-Kennedy on 1 June 1893 and had three children.
