theCoderSchool, founded in 2014 and based in California's Silicon Valley, was started by two childhood friends who spotted a gap in the market when looking for a coding school for their own children. With schools in 20 US locations, growing at a projected rate of 10–15 new ones per year, and summer camps across the US, on a weekly basis they teach over 2000 kids how to code with infectious humour, enthusiasm and a sense of fun. Simon Basher needs little introduction as the illustrator of Kingfisher's extensive range of Basher titles, which have sold over 3 million copies to date. His bestselling book is Basher Science: The Complete Periodic Table. Basher's illustration style, often described as graphic surrealism, is quirky and humorous and has proved popular with children and students as well as parents and educators.
