Sebastien Braun was born in Strasbourg. He loved drawing as a child, but as there were no art lessons at his secondary school, so he opted to study history at university. Fortunately, his course was in the same building as the art department, he swapped and studied that instead. After teaching applied art to sixth formers for a few years, he became a freelance illustrator. Since moving to London, he has became a very successful illustrator of children's books, including Santa's Noisy House and Busy Holiday. He lives in the Cotswolds with his wife and two boys.
