Daniel used that event to raise funds for the National Society for Epilepsy because it was after a series of childhood seizures that his extraordinary number and memory abilities began, aligning him with that rare circumstance of the ‘acquired savant’ in which such exceptional skills surface following some CNS injury or disease. He is proud of the monies raised on behalf of this organization, and certainly gave this worthy cause a good deal of visibility.
In addition to number and massive memory skills, Daniel has exceptional language skills as well. He speaks French, German, Spanish, Lithuanian, Esperanto and Icelandic. He learned the difficult Icelandic language in seven days which was carefully documented in the one hour film about Daniel titled Brainman.
That documentary, Brainman, which also goes by the alternative title of "The Boy with the Incredible Brain", has been shown in both the United Kingdom and the United States on various channels. Whenever that film appears in this country on the Discovery Channel it generates a number of inquiries to this Web site about Daniel and his remarkable abilities. In one scene Daniel is asked to calculate 37 raised to the power of 4. He gave the correct answer of 1,874,161 in less than one minute. Then asked to divide 13 by 97 he outdistances the interviewers computer calculator by 32 decimal places with the ability to go to over 100 decimal places if one wanted him to recite that long string of digits. The film also shows Daniel’s ability to memorize the position of all the chess pieces on a particular board at a point in time, and, as mentioned, documents Daniel’s acquisition of the Icelandic language in only a week’s time.
Presently Daniel maintains a Web site at www.optimnem.co.uk which offers a variety of educational courses for "promoting key skill areas such as literacy and numbers through spatial learning strategies for English, Math, French, German and Spanish." The site provides the following description of Daniel:
"Daniel Tammet was born in London, in 1979, with congenital childhood epilepsy. A series of seizures as a young child changed forever the way Daniel saw the world around him. For one thing, Daniel was able to literally ‘see’ numbers in his head as if they were images. Not surprisingly, he quickly became proficient in number patterns, able to figure various roots, powers; even the decimal expansions for prime number fractions — often quicker than a friend with a calculator."A high-functioning autistic savant, Daniel outgrew his disability. His astonishing mental skills, however, remained. As an example, following an invitation from organizers, he attended the largest ever ‘Memory Olympics’ in London in 2000. He won a gold medal and was subsequently invited to London’s Institute of Neurology to undergo tests for a landmark study of prodigious mental ability. The summarized data, co-written by some of Britain’s leading brain scientists, appeared in the New Year 2003 edition of the highly prestigious Nature neuro-scientific magazine."
While filming Brainman, Daniel had the opportunity to meet and interact with Kim Peek. Both Kim and Daniel have massive memory capacity quantitatively, but the nature of that massive memory differs somewhat qualitatively. Kim has a huge store of factual material, but disqualifies himself a bit when it comes to math simply saying that is not an area of interest or strength for him. Daniel’s strength, on the other hand, is not in factual storage, but rather the ability to faithfully recall huge strings of numbers (or other items) which he literally ‘sees’ before him as if on a tapestry of images, and in his ability to manipulate those numbers with incredible speed in various calculations and derivations. Both Kim and Daniel, however, are continually flooded with data within their areas of interest and expertise, vacuuming up such data instantly, and massively, storing it for later retrieval with incredible speed and seemingly bottomless depth.
Presently Daniel is writing a book about his life, and his special skills, which is scheduled to be published in August 2006. That book should provide a great deal of insight into a very unique and incredible memory in this very unusual, but fascinating, circumstance of ‘acquired’ savant skills.
There have been a number of articles about Daniel, particularly in the British press, which provide additional background and glimpses into Daniel’s unique and extraordinary memory capacities. One such article can be accessed at www.guardian.co.uk/weekend/story/0,,1409903,00.html.
I had an opportunity to meet Daniel on his visit to Milwaukee when filming Brainman. His digit span memory exceeded that of any one I had ever tested before and other tests of recall were, of course, entirely accurate. Daniel is a very polite, soft-spoken, gentle person; pre-occupied at times and shy, not boastful, about his enormous abilities. He described to me how he assigns a shape and color to each number, reaching into the thousands. As he remembers, or computes, these images appear as just that — images and colors — which he ‘simply’ recites as he views them. When computing, the images merge together and out comes the new, correct combination for his instant inner viewing. At the Calatrava art museum where we met, there was a very tall tree-like structure composed of variously shaped and colored blown-glass composite pieces, positioned together like ornaments on a Christmas tree. Daniel identified with many of those shapes and colors, each representing, one of the numbers and images continually present in his head. While it is difficult to image exactly what Daniel is experiencing as he ‘sees’ numbers and objects flowing before him, that tree-like composite of colors and shapes provided, for me, some reference point to better sense what that colorful, moving tapestry must be like — imbedded as it is — with the huge store of numbers which have become, by his own description, Daniel’s friends.
It was a very pleasant visit. Daniel summed it up this way: "The line between profound talent and profound disability is really a surprisingly thin one." The Brainman narrator concludes, correctly, that "The way Daniel can describe his inner world is giving scientists a window into the brain that they have not seen before." But the narrator also comments, correctly, that "this journey of explanation is just beginning."
