George Robert Waterhouse (1810-1888) was an English naturalist, curator, and zoologist who made significant contributions to the study of mammals and insects. Born in Somers Town, London, he developed a passion for entomology through his father’s influence. Waterhouse co-founded the Entomological Society of London in 1833 and served as its honorary curator. His interest extended to mammals, and he authored A Natural History of the Mammalia (1846-48), covering marsupials and rodents. Waterhouse declined an invitation to join Charles Darwin on the Beagle voyage but later became the curator of the mammals and beetles collected during that expedition. His legacy includes describing species like the numbat and the Syrian or golden hamster. Waterhouse’s dedication to natural history and his role as keeper at the British Museum of Natural History left an indelible mark on the scientific community.
