Best known as the publisher of Icones Ornithopterorum (1898-1906), the first monograph on bird wing butterflies, but he also interested himself in other insects, molluscs and minerals. His insect collection amounting to 105,765 specimens, of which 56,828 are Coleoptera, is in the NMW. There is a good account of Rippon by Ashley Kirk-Spriggs in Archives of Natural History 22(1), 1995, pp.97-118. He was born in Bocking, Essex and appears to have started his professional life as a ‘Professor of Musick’ and he published some light songs and piano music.
