Rupert Colley was a librarian in Enfield for 22 years until September 2011. A history graduate, he launched the original History In An Hour in 2009 with a website, blog and ‘World War Two In An Hour’ as an iPhone app. He then expanded it to Kindle, iBooks and into the USA with a series of titles, and enlisted new writers by encouraging guest bloggers on the website. History In An Hour was acquired by HarperCollins in 2011.
