John Van Voorst (15 February 1804 – 1898) was an English publisher of natural history books. His publications were noted for their good quality, reasonable prices and the frequent inclusion of superior illustrations by notable artists.
John Van Voorst was born in Highgate on 15 February 1804, to a family of Dutch descent.  He served a six-year apprenticeship in Wakefield from the age of 16 before returning to London to work for publishers Longman, Green, Orme, Hurst & Co.   He set up his own business in Paternoster Row in 1833. Initially, he published illustrated reprints, including Gray's Elegy in a Country Church-Yard and Goldsmith's Vicar of Wakefield,   but he soon began to specialise in natural history books, often illustrated, and was appointed bookseller to the Zoological Society in 1837.
Some of his most noted publications were British Fishes (by Yarrell, 1835), British Quadrupeds (by Bell, 1836), British Birds (by Yarrell, 1837).   With the exception of Darwin, Voorst worked with most of the noted naturalists of his day including Alfred Russel Wallace, Philip Henry Gosse, George Johnston, Edward Forbes, Edward Newman and Richard Owen. The illustrators he employed were equally notable, including such artists as John Constable, William Mulready, Richard Westall, Edwin Landseer, and Copley Fielding. In 1871 his list of current titles comprised 224 books or learned journals, the majority covering topics in natural history.
Van Voorst published the journal The Zoologist , for more than forty years, starting in January 1843, until 1886.
He also published several children's books, including the anonymously published works of author and sanitary reformer Anne Bullar. He retired in 1886, his assistants taking over as Gurney and Jackson.  
He was a founder member of the Royal Microscopical Society in 1839, and became a Fellow of the Linnean Society in 1853. 
After retirement in 1886, Van Voorst remained active until his death in London on 24 July 1898. 
Richard Bowdler Sharpe was an English zoologist and ornithologist who worked as curator of the bird collection at the British Museum of natural history. In the course of his career he published several monographs on bird groups and produced a multi-volume catalogue of the specimens in the collection of the museum. He described many new species of bird and also has had species named in his honour by other ornithologists including Sharpe's longclaw and Sharpe's starling.
William Yarrell was an English zoologist, prolific writer, bookseller and naturalist admired by his contemporaries for his precise scientific work.
Richard Anthony Salisbury, FRS was a British botanist. While he carried out valuable work in horticultural and botanical sciences, several bitter disputes caused him to be ostracised by his contemporaries.

He did not travel, but collected, described and illustrated many species based on the collections of other naturalists. His many books were successful in his time.

Francis Walker was an English entomologist. He was born in Southgate, London, on 31 July 1809 and died at Wanstead, England on 5 October 1874. He was one of the most prolific authors in entomology, and stirred controversy during his later life as his publications resulted in a huge number of junior synonyms. However, his assiduous work on the collections of the British Museum had great significance.
William Thompson was an Irish naturalist celebrated for his founding studies of the natural history of Ireland, especially in ornithology and marine biology. Thompson published numerous notes on the distribution, breeding, eggs, habitat, song, plumage, behaviour, nesting and food of birds. These formed the basis of his four-volume The Natural History of Ireland, and were much used by contemporary and later authors such as Francis Orpen Morris.

William Chapman Hewitson was a British naturalist. A wealthy collector, Hewitson was particularly devoted to Coleoptera (beetles) and Lepidoptera and, also, to birds' nests and eggs.

He contributed to and published many works on entomology and ornithology and was an accomplished scientific illustrator.

Illustrations of the Family of Psittacidae, or Parrots is an 1832 book containing 42 hand-coloured lithographs by Edward Lear. He produced 175 copies for sale to subscribers as a part-publication, which were later bound as a book. Lear started painting parrots in 1830 when he was 18 years old, and to get material for his book he studied live birds at the London Zoo and in private collections. The latter included those of Edward Smith Stanley, later 13th Earl of Derby, who had a large menagerie at Knowsley Hall, and Benjamin Leadbeater, a taxidermist and trader in specimens. Lear drew onto lithographic plates for printing by Charles Joseph Hullmandel, who was known for the quality of his reproductions of fine art.
