Sven Hassel was the pen name of the Danish-born Børge Willy Redsted Pedersen (19 April 1917  – 21 September 2012) who wrote novels set during World War II. In Denmark he used the pen name Sven Hazel. Although he is arguably one of the most sold Danish authors, at most second to Hans Christian Andersen, Danish public libraries, as of 2012, did not stock his books.
