Buckingham Palace to demonstrate the tame character of zebras to the public Rothschild studied zoology at Magdalene College, Cambridge. Meeting
Albert Günther sparked his interest in the
taxonomy of birds and butterflies. Although Rothschild himself travelled and collected in Europe and North Africa for many years, his work and health concerns limited his range, and beginning while at Cambridge he employed others (explorers, professional collectors, and residents) to collect for him in remote and little-known parts of the world. He also hired taxidermists, a librarian, and, most importantly, professional scientists to work with him to curate and write up the resulting collections:
Ernst Hartert, for birds, from 1892 until his retirement at the age of 70 in 1930 and
Karl Jordan for entomology, from 1893 until Rothschild's death in 1937. At its largest, Rothschild's collection included 300,000 bird skins, 200,000 birds' eggs, 2,250,000 butterflies, and 30,000 beetles, as well as thousands of specimens of mammals, reptiles, and fishes. They formed the largest zoological collection ever amassed by a private individual. The
Rothschild giraffe (
Giraffa camelopardalis rothschildi), a subspecies with five
ossicones instead of two, was named after him. Another 153 insects, 58 birds, 17 mammals, three fish, three spiders, two reptiles, one millipede, and one worm also carry his name. Rothschild opened his private museum in 1892. It housed one of the largest
natural history collections in the world and was open to the public. In 1932, he was forced to sell the vast majority of his bird collection to the
American Museum of Natural History after he had been blackmailed by a former mistress. In 1933, he was one of eleven people involved in the appeal that led to the foundation of the
British Trust for Ornithology (BTO), an organization for the study of birds in the British Isles. On his death in 1937, his museum and all of its contents were given in his will to the
British Museum (of which the
Natural History Museum, London, was then a part), the greatest accession that the institution has ever received. The
Walter Rothschild Zoological Museum at
Tring is now a division of the Natural History Museum. Following a visit to Hungary in 1902, Rothschild brought six live edible dormice (
Glis glis) back to
Tring. Some of them escaped and started breeding successfully in the wild. They have now become a localized pest over an area of approximately 200 square miles in a triangle between Luton, Aylesbury, and Beaconsfield, and there are estimated to be at least 10,000 of them. Even though considered an
invasive species, they are protected under the
Wildlife and Countryside Act 1981. Rothschild was awarded an honorary doctorate by the
University of Giessen in 1898, was elected a Trustee of the British Museum in 1899, and was elected a Fellow of the
Royal Society in 1911. == Political career ==
