Reginald Walter Hooley (1865–1923) was a businessman who achieved scientific recognition through his work as an amateur paleontologist. Active during the late nineteenth and early twentieth centuries, Hooley focused his geological and paleontological efforts on the Isle of Wight, where he actively collected fossil specimens. Despite not being a professional academic, his dedicated field research and collection efforts yielded significant discoveries that caught the attention of the wider scientific community. Hooley's most notable contribution to the field of paleontology was his formal description of the dinosaur species Iguanodon atherfieldensis. This specimen, which was later reclassified as Mantellisaurus, remains a key point of reference in the study of ornithopod dinosaurs. Through this description, Hooley bridged the gap between amateur collecting and formal scientific literature, leaving behind a legacy as a significant contributor to the documentation of prehistoric life.
