Daniel Tammet FRSA (born 31 January 1979) is an English writer, essayist, translator, and autistic savant. His 2006 memoir, Born on a Blue Day, about his life with high-functioning autism and savant syndrome, was named a "Best Book for Young Adults" in 2008 by the American Library Association. Tammet's second book, Embracing the Wide Sky, was one of France's best selling books of 2009. Thinking in Numbers, Tammet's third book, was published by Hodder in the UK on 16 August 2012, and by Little, Brown in the United States and Canada on 30 July 2013. His books have been published in 20 languages. He was elected a Fellow of the Royal Society of Arts in 2012.
Tammet was born Daniel Paul Corney and raised in Barking, East London, England, the eldest of nine children. He suffered epileptic seizures as a young child, which he subsequently outgrew following medical treatment. At age twenty-five, he was diagnosed with Asperger syndrome by Professor Simon Baron-Cohen of the Autism (Spectrum) Research Centre at Cambridge University. Tammet is one of fewer than a hundred "prodigious savants" according to Dr. Darold Treffert, the world's leading researcher in the study of savant syndrome.
Tammet has been studied repeatedly by researchers in Britain and the United States, and has been the subject of several peer-reviewed scientific papers. Professor Allan Snyder at the Australian National University has said of Tammet: "Savants can't usually tell us how they do what they do. It just comes to them. Daniel can describe what he sees in his head. That's why he's exciting. He could be the 'Rosetta Stone'."
In his mind, he says, each positive integer up to 10,000 has its own unique shape, colour, texture and feel. He has described his visual image of 289 as particularly ugly, 333 as particularly attractive, and pi, though not an integer, as beautiful. The number 6 apparently has no distinct image yet what he describes as an almost small nothingness, opposite to the number 9 which he calls large, towering, and quite intimidating. Tammet also describes the number 117 as "a handsome number. It's tall, it's a lanky number, a little bit wobbly".  In his memoir, Tammet states experiencing a synaesthetic and emotional response for numbers and words.
Tammet is a polyglot. In Born On A Blue Day he writes that he 'knows' ten languages: English, Finnish, French, German, Lithuanian, Esperanto, Spanish, Romanian, Icelandic and Welsh. In Embracing the Wide Sky, Tammet writes that he learned conversational Icelandic in a week and then appeared on an interview on Kastljós on RÚV speaking the language.
In 2002 Tammet launched the website, Optimnem. The site offers language courses (currently French and Spanish) and has been an approved member of the UK's National Grid for Learning since 2006.
Born on a Blue Day, Tammet's memoir of a life with Asperger's syndrome, received international media attention and critical praise. Booklist's Ray Olson stated that Tammet's autobiography was "as fascinating as Benjamin Franklin's and John Stuart Mill's" and that Tammet wrote "some of the clearest prose this side of Hemingway". Kirkus stated that the book "transcends the disability memoir genre".
For his US book tour, he appeared on several television and radio talk shows and specials, including 60 Minutes and Late Show with David Letterman. In February 2007 Born on a Blue Day was serialised as BBC Radio 4's Book of the Week in the United Kingdom.
Tammet's second book, Embracing the Wide Sky was published in 2009. Professor Allan Snyder, director of Sydney University's Centre for the Mind, called the work 'an extraordinary and monumental achievement'. Tammet argues that savant abilities are not "supernatural" but are "an outgrowth" of "natural, instinctive ways of thinking about numbers and words". He suggests that the brains of savants can, to some extent, be retrained, and that normal brains could be taught to develop some savant abilities.
After the World Memory Championships, Tammet participated in a group study, later published in the New Year 2003 edition of Nature Neuroscience. The researchers investigated the reasons for the memory champions' superior performance. They reported that they used "strategies for encoding information with the sole purpose of making it more memorable", and concluded that superior memory was not driven by exceptional intellectual ability or differences in brain structure.
In another study, Simon Baron-Cohen and others at the Autism Research Centre at the University of Cambridge tested Tammet's abilities in around 2005. He was found to have synaesthesia according to the "Test of Genuineness-Revised" which tests the subjects' consistency in reporting descriptions of their synaesthesia. He performed well on tests of short term memory (with a digit-span of 11.5, where 6.5 is typical). Conversely, test results showed his memory for faces scored at the level expected of a 6–8 year old child in this task. The authors of the study speculated that Tammet's savant memory could be a result of synaesthesia combined with Asperger syndrome, or it could be the result of mnemonic strategies.
Baron-Cohen, Bor and Billington investigated whether his synaesthesia and Asperger syndrome explained his savant memory abilities in a further study published in Neurocase in 2008. They concluded that his abilities might be explained by hyperactivity in one brain region (the left prefrontal cortex), which results from his Asperger syndrome and synaesthesia. On the Navon task, relative to non-autistic controls, Tammet was found to be faster at finding a target at the local level and to be less distracted by interference from the global level. In an fMRI scan, "Tammet did not activate extra-striate regions of the brain normally associated with synaesthesia, suggesting that he has an unusual and more abstract and conceptual form of synaesthesia". Published in Cerebral Cortex (2011), an fMRI study led by Professor Jean-Michel Hupé at the University of Toulouse (France) observed no activation of colour areas in ten synaesthetes. Hupé suggests that synaesthetic colour experience lies not in the brain's colour system, but instead results from "a complex construction of meaning in the brain, involving not only perception, but language, memory and emotion".
In his book Moonwalking with Einstein (2011), science journalist and former US Memory Champion Joshua Foer speculates that study of conventional mnemonic approaches has played a role in Tammet's feats of memory. While accepting that Tammet meets the standard definition of a prodigious savant, Foer suggests that his abilities may simply reflect intensive training using standard memory techniques, rather than any abnormal psychology or neurology per se. In a review of his book for the New York Times, psychologist Alexandra Horowitz described Foer's speculation as among the book's few "missteps", questioning whether it would matter if Tammet had used such strategies or not.
Tammet met his first partner, software engineer Neil Mitchell, in 2000. Tammet lived with him in Kent, where they had a quiet life at home with their cats, preparing meals from their garden. Tammet and Mitchell operated the online e-learning company Optimnem, where they created and published language courses.
Tammet now lives with a new partner, Jérôme Tabet, a French photographer whom he met while promoting his autobiography. Although he has said that he did not think he would be here if it were not for the love and support of Mitchell, more recently he noted that he used to live a rigid existence aimed at calming his many anxieties—"I was very happy, but it was a small happiness"—whereas now, as the subtitle of Embracing the Wide Sky: A tour across the horizons of the mind asserts, he believes that we ought to seek to liberate our brains—a belief reflected in his new life:
My life used to be very simple and regimented but since then I have travelled constantly and given lots of lectures and it just changed me... It made me much more open, much more interested in, I guess, the full potential of what my mind could do... Because of that change I grew and in a sense I grew apart from my long-term partner, so we parted amicably in 2007, and a short while later I met my current partner, who is from France so I decided to go and live with him in Avignon.

Mänti is a constructed language that Tammet has created. The word 'Mänti' comes from the Finnish word for 'pine tree' (mänty). Mänti uses vocabulary and grammar from the Finnic languages. Some sample words include:
|kellokült||lateness, tardiness||viitsimatus, hilinemine||myöhästyneisyys||Literally "clock-debt". In Finnish kello = a clock / a bell|
|puhukello||telephone||telefon||puhelin||Literally "speak-bell". In Finnish puhua = to speak|
|tontöö||music||muusika||musiikki||Literally "tone-art". In Estonian töö = work|
|koet saapat||footwear||jalanõud||jalkineet||In Finnish saappaat = boots. In Estonian saapad = boots.|
