English essayist, novelist, poet, translator, and autistic savant. His 2006 memoir, Born on a Blue Day, about his life with Asperger syndrome and savant syndrome, was named a “Best Book for Young Adults” in 2008 by the American Library Association Young Adult Library Services magazine. His second book, Embracing the Wide Sky, was one of France’s best-selling books of 2009. His third book, Thinking in Numbers, was published in 2012.

At age twenty-five, he was diagnosed with Asperger syndrome by Simon Baron-Cohen of the University of Cambridge Autism Research Centre. He is one of fewer than a hundred “prodigious savants” according to Darold Treffert, the world’s leading researcher in the study of savant syndrome.
He was the subject of a documentary film, Extraordinary People: The Boy with the Incredible Brain, first broadcast on the British television station Channel 4 on 23 May 2005.
Tammet met software engineer Neil Mitchell in 2000. They lived in Kent, England, where they had a quiet life at home with their cats, preparing meals from their garden. He and Mitchell operated the online e-learning company Optimnem, where they created and published language courses. Tammet now lives in Paris, France, with his husband Jérôme Tabet, a photographer whom he met while promoting his autobiography.
