Francis Walker (31 July 1809 – 5 October 1874) was an English entomologist. 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.

Walker was contracted by the British Museum between June 1848 and late 1873 to catalogue their insects (except Coleoptera). He was born in Southgate, England on 31 July 1809 and died at Wanstead, England on 5 October 1874. Walker added an immense amount of material to the collections of the British Museum and wrote over 300 scientific papers and notes. He is best known for his catalogues of Orthoptera, Neuroptera, Hemiptera, Diptera, Lepidoptera and Hymenoptera. Collaborating with Alexander Henry Haliday, a lifelong friend, he was one of the first students of the Chalcidoidea. He was also a close friend of John Curtis. Walker was a fellow of the Entomological Society. Walker's specimens are in the Natural History Museum, London; Hope Department of Entomology, University of Oxford; the National Museum of Ireland, Dublin; Zoologische Staatssammlung München and the School of Medicine, Cairo, Egypt.

Family and childhood[edit]

Francis Walker was the son of John Walker of Arnos Grove, who was a fellow of the Royal Society, the Linnean Society and the Royal Horticultural Society. Born into a wealthy and educated family, Francis spent the years 1816 (when he was seven years old) to 1820 (when he was eleven) in Switzerland at Geneva, Lucerne and Vevey where the family party was joined by Madame de Staël, the poet Lord Byron and some Swiss naturalists gathered around Nicolas Théodore de Saussure. With his brother Henry (1825–1892), Francis collected butterflies on an ascent of Mount Pilatus in 1818 and so was an entomologist at age nine. In 1840 Walker married Mary Elizabeth Ford.

Occupation[edit]

In 1834 Walker took up the editorship of the Entomological Magazine for one year and unpaid and in 1837 he began working on a contract basis for the British Museum where he remained until 1863. He lived at Arnos Grove and relied on family money for his main income.

Traveller and alpinist[edit]

Walker was a traveller with a liking for mountains. His known trips are:

Major works[edit]

Different views of Walker[edit]

Walker is notable in the present time for the large number of synonymous taxa he described. A careless taxonomist by today's standards, he often gave more than one name to the same species. In this respect, however, he was no worse than many entomologists of his time; what makes for the more common occurrence of Walker's taxa in synonymy is the sheer volume of his work.

An unsigned obituary by J. T. Carrington[citation needed] began "More than twenty years too late for his scientific reputation, and after having done an amount of injury almost inconceivable in its immensity, Francis Walker has passed from among us".[1] Edward Newman, in contrast described him as the "most voluminous and most industrious writer on Entomology this country has ever produced" and said of him "I never met anyone who possessed more correct, more diversified, or more general information, or who imparted that information to others with greater readiness and kindness."[2]

Kenneth G.V. Smith wrote:[3]

[Walker's] 'Catalogues of Insects in the British Museum Collections' will always stand as a tribute to his industry. Walker (1836) also described the Diptera from Captain P. P. King's collection made on the first surveying voyage of Adventure and Beagle. Fortunately, many of his descriptions of Darwin's insects will endure because they were of little known groups from little worked regions and most of his types are still in the British Museum (Natural History). For a recent balanced account of this remarkable man see Graham (1979).[4]
