Wallace Letters Online (WLO), an online archive giving everyone access to the correspondence of Alfred Russel Wallace, co-discoverer of the theory of evolution by natural selection, is launched today by comedian and naturalist Bill Bailey at the Natural History Museum. Bailey will also be launching Wallace100, a programme of events to mark the centenary of Wallace’s death, by unveiling an impressive portrait of Wallace in the Museum’s iconic Central Hall, near the famous statue of Darwin.
WLO brings together all surviving letters to and from Wallace, both personal and scholarly, for the first time. His unpublished correspondence is scattered across the collections of more than 100 institutions worldwide so it has been very difficult for people to study, until now.
Highlights in WLO include the fascinating letters he wrote and received during his epic trip to the Malay Archipelago between 1854 and 1862, and his complete correspondence with Charles Darwin, which has never been published in full before. Online materials will also include other important documents, such as Wallace's notebooks from the Museum’s Wallace Family Archive.
Alfred Russel Wallace is considered by many to be one of the greatest scientists of all time. Not only did he independently discover natural selection, he also founded the science of evolutionary biogeography; the study of the geographical distribution of plants and animals.
He made significant contributions to academic fields as diverse as anthropology and epidemiology, and was an intrepid traveller and avid collector of natural history specimens who sent back thousands of species new to science from South America and south-east Asia.
About 4,500 letters to and from Wallace are known to survive, with more than half of these held in the collections of the Natural History Museum (1,200) and the British Library (1,600). The Wallace Correspondence Project has so far digitised about 95 per cent of the letters, and is searching for others hidden away in libraries and private collections around the world. Wallace Letters Online is the Web interface to the Wallace Correspondence Project's electronic database of Wallace's letters.
Dr George Beccaloni, Director of the Wallace Correspondence Project and a curator here at the Museum says, ‘Collating, transcribing and making this material freely available online marks a huge advance in understanding this great man. It presents a wealth of new information for those interested in Wallace’s life, work and beliefs. I hope it will help build a new and more accurate picture of him, and help to bring him out of Darwin's shadow.'
More details and highlights of WLO
WLO aims to catalogue and provide images and transcripts of all known letters sent to or written by Wallace (including the original envelopes and any enclosures), plus selected letters between others which contain important information pertaining to Wallace (e.g. a letter from Charles Darwin to Thomas Huxley which discusses Wallace). WLO also includes a selection of other important manuscript documents and other items which are not letters e.g. Wallace's notebooks in the Museum's Wallace Family Archive.
WLO currently contains records of 4,151 letters, of which 2,026 were written by ARW, 1,856 were sent to ARW and 269 are third party letters which pertain to ARW. It also contains details of 26 other documents such as notebooks.
WLO currently contains about 95% of Wallace's known surviving correspondence, including all of Wallace's early (pre. 1863) correspondence, and all of the surviving letters he sent or received during his epic trip to the Malay Archipelago between March 1854 and April 1862. It also includes the complete surviving Darwin-Wallace correspondence in full for the first time. Previous published compilations of the Darwin-Wallace letters (i.e. Darwin (1893), Marchant (1916)) are incomplete and the published transcripts were often heavily edited and sometimes suffer from important omissions of text.

There follows a selection of key letters relating to some of Wallace's greatest discoveries: evolution by natural selection; the Wallace Line; and warning colouration.
Early life (1823-1848)
WCP346: Wallace to Henry Walter Bates, 28 December 1845. Wallace discusses his views of the book Vestiges of the Natural History of Creation - the work which convinced him of the reality of evolution and started him on his quest to discover the mechanism which drives it. For more information about this letter see here.
WCP348: Wallace to Bates, 11 October 1847. This letter contains his famous statement "I begin to feel rather dissatisfied with a mere local collection - little is to be learnt by it. I sh[ould]d like to take some one family, to study thoroughly - principally with a view to the theory of the origin of species. By that means I am strongly of [the] opinion that some definite results might be arrived at." This was the prelude to Wallace suggesting to Bates that they go on a expedition to Brazil to collect birds, butterflies and beetles in order to try to discover what drives the evolution of new species. For more information see here.
Four year expedition to the Amazon Basin (1848-1852)
WCP349: Wallace to Richard Spruce, 19 September 1852. "On Friday the 6th of August...about 9 o’clock in the morning just after breakfast the Captain (who was the owner of the vessel) came into the cabin & said "I am afraid the ship’s on fire. Come & see what you think of it"". After four years in Brazil, Wallace sailed back to England taking with him the most valuable part of the collection of natural history specimens he had made whilst there. Twenty-six days into the voyage, in the mid-Atlantic, the ship caught fire and sank, taking his specimens down with it. Wallace and the crew took to the lifeboats and miraculously, were rescued 10 days later. This letter describes the sinking.
Eight year expedition to the Malay Archipelago (1854-1862)
WCP1703: Wallace to his agent Samuel Stevens, 21 August 1856. This letter is the first mention of Wallace's famous discovery of what was later named the Wallace Line - the invisible boundary between the animals of Asia and the Australian region. He says "The Birds have however interested me much more than the insects, they are proportionally much more numerous, and throw great light on the laws of Geographical distribution of Animals in the East. The Islands of Baly & Lombock for instance, though of nearly the same size, of the same soil aspect elevation & climate and within sight of each other, yet differ considerably in their productions, and in fact belong to two quite distinct Zoological provinces, of which they form the extreme limits. As an instance I may mention the Cockatoos, a group of birds confined to Australia & the Moluccas, but quite unknown in Java Borneo Sumatra & Malacca. One species however (Plyctolophus sulphureus) is abundant in Lombock but is unknown in Baly, the island of Lombock forming the extreme eastern limit of its range & that of the whole family. Many other species illustrate the same fact & I am preparing a short account of them for publication." For more information see here.
WCP1454: Wallace to Joseph Dalton Hooker, 6 October 1858. This is the only letter which survives of those surrounding Wallace's discovery of natural selection and the subsequent publication of the theory with Charles Darwin. The letter illustrates Wallace's good nature and demonstrates that he was more interested in discovering new ideas than reaping personal glory from publishing them. For more information about the events surrounding Darwin and Wallace's joint publication on natural selection see here.
Later life in England (1862-1913)
WCP609: Charles Darwin to Wallace, 23 February 1867. Darwin and Wallace became good friends. In this letter Darwin writes "On Monday evening I called on Bates & put a difficulty before him, which he could not answer, & as on some former similar occasion, his first suggestion was, "you had better ask Wallace". My difficulty is, why are caterpillars sometimes so beautifully & artistically coloured?" Darwin was puzzled because his theory of sexual selection (where females choose their mates based on how attractive they are) would not apply to caterpillars since they are immature.
Wallace replied the next day (WCP4083) with the suggestion that since some caterpillars "...are protected by a disagreeable taste or odour, it would be a positive advantage to them never to be mistaken for any of the palatable catterpillars, because a slight wound such as would be caused by a peck of a bird’s bill almost always I believe kills a growing catterpillar. Any gaudy & conspicuous colour therefore, that would plainly distinguish them from the brown & green eatable catterpillars, would enable birds to recognise them easily as at a kind not fit for food, & thus they would escape seizure which is as bad as being eaten.
Thus the concept of warning or aposematic colouration in animals was born.
WCP575: The Secretary of The Royal Society to Wallace, 6 November 1890. Informing Wallace (with unintended irony) that "... the Royal Society have awarded to you the Darwin Medal for your Independent Origination of the Theory of the Origin of Species by Natural Selection."
WCP543: The King's Private Secretary to Wallace, 2 November 1908. Informs Wallace that he is to be awarded the Order of Merit by the King "...in recognition of the great services which you have rendered to science." The Order is awarded by the ruling Monarch and is the highest civilian honour of Great Britain. It has been described as "...quite possibly, the most prestigious honour one can receive on planet Earth." There are only 24 living individuals in the Order at any given time, not including honorary appointees.
WCP4244: Wallace to the Biology Students at the University of Colorado, 12 January 1912. In this charming letter, Wallace aged 89 tells the students how "The wonders of nature have been the delight and solace of...[his]...life." and how "...nature has afforded...[him]...an ever increasing rapture, and the attempt to solve some of her myriad problems an ever-growing sense of mystery and awe". He ends by saying "I sincerely wish you all some of the delight in the mere contemplation of nature’s mysteries and beauties which I have enjoyed, and still enjoy."
B) Other documents
WCP4756: Wallace's personal annotated copy of the famous scientific paper he co-authored with Charles Darwin in 1858, in which the theory of evolution by natural selection was proposed for the first time. For more information about this historically important item see here.
WCP4766 and WCP4767: Wallace's two scientifically important 'Species Register' notebooks from his trip to the Malay Archipelago, which meticulously detail the species and specimens of insects, birds and other animals he collected on numerous islands he visited.
WCP4779 and WCP4806: Two of Wallace's address books, which cover the period from c. 1864 to his death in 1913, i.e. most of his adult life. Contacts listed include Charles Darwin, Rajah James Brooke (ruler of Sarawak) and hundreds of other, many of whom were very famous at the time.
The earlier of the address books was used by him between c. 1864 and c. 1872, both for listing addresses and for recording his investments in shares etc. The investment records occupy one end of the book and the addresses start from the other end. Also in this book are some interesting lists, such as a list of the people which Wallace sent copies of his book The Malay Archipelago to when it was first published, and a list of "Persons to whom Hampden has abused me" (John Hampden was a flat earth believer who persecuted Wallace for very many years).
The second address book has been 'opened from both ends' like the first - with address lists running from one end, and notes about garden plants starting at the other end. There are four separate lists of addresses in this book, each of which is arranged from A to Z, and between each and the next address list are various notes and lists, some of which are historically quite important.
