John Samuel Budgett was a British zoologist and embryologist. He spent most of his short career on the genus Polypterus (bichir), found in the lakes, river margins, swamps and floodplains of tropical central and western African and the Nile River system. He died to blackwater fever shortly after his return to England. This happened on the very day that he was suppose to deliver a lecture of his work to the Zoological Society of London. He didn't have time to write a report, but he did leave a full set of drawings and specimens. It was left to his friend and colleague John Graham Kerr to interpret them and write the report

Louis Fraser was a British zoologist and collector. Fraser had worked as an assistant in the Indian Museum at Calcutta around 1888. He worked for fourteen years at the museum of the Zoological Society of London. He worked with the anatomist Richard Owen on studies of the emu and rhea. He participated in the Niger expedition of 1841 as the African Civilisation Society's scientist. Upon his return he became in charge of Lord Derby's collection at Knowsley Hall. In 1846 he was sent by Lord Derby to collect in north Africa. In 1848 he became conservator at Knowsley Hall. He wrote Zoologica Typica, or figures of the new and rare animals and birds in the collection of the Zoological Society of London, published in 1849. In 1850, Fraser was appointed Consul of Quidah, Dahomey (now Benin), West Africa. Around 1857-1859 he collected birds and mammals in Ecuador for Philip Lutley Sclater of the Zoological Society of London, and the year after in California. Upon his return to London, he opened a shop in Regent's Park, London, selling exotic birds. The last years of his life he spent in America. Fraser wrote a Catalogue of the Knowsley Collections (1850) and described several new species including the Derbyan parakeet Psittacula derbiana named after his employer.[2] A number of species and subspecies have been named in his honour, including Fraser's anole (Anolis fraseri ), Fraser's ground snake (Liophis epinephelus fraseri ), a centipede snake (Tantilla fraseri ),[5] Fraser's eagle-owl (Bubo poensis), Fraser's warbler (Myiothlypis fraseri ),[6] and Fraser's musk shrew (Crocidura poensis)

Daniel Giraud Elliot was an American zoologist. He used his wealth to publish a series of colour-plate books on birds and animals. Elliot wrote the text himself and commissioned artists such as Joseph Wolf and Joseph Smit, both of whom had worked for John Gould, to provide the illustrations. The books included A Monograph of the Phasianidae (Family of the Pheasants) (1870–72), A Monograph of the Paradiseidae or Birds of Paradise (1873),[3] A Monograph of the Felidae or Family of Cats (1878) and Review of the Primates (1913).

He was also curator of zoology at the Field Museum in Chicago
Christoph Gottfried Andreas Giebel was a German zoologist and palaeontologist. He was a professor of zoology at the University of Halle where he managed the zoology collections at the museum. His interests were in systematics and palaeontology and he opposed Darwinian evolution. He published several works including Palaozoologie (1846); Fauna der Vorwelt (1847-1856); Deutschlands Petrefacten (1852); Odontographie (1855); Lehrbuch der Zoologie (1857); and Thesaurus ornithologiae (1872-1877).
Franz Martin Hilgendorf was a German zoologist and palaeontologist. Hilgendorf's research on fossil snails from the Steinheim crater in the early 1860s became a palaeontological evidence for the theory of evolution published by Charles Darwin in 1859. Darwin acknowledged the findings of Hilgendorf and referred to his research in the sixth edition of On the Origin of Species, 1872.
