George Manville Fenn (3 January 1831 in Pimlico - 26 August 1909 in Isleworth) was a prolific English novelist, journalist, editor and educationalist. Many of his novels were written for young adults. His final book was a biography of his fellow writer for juveniles, George Alfred Henty. Fenn's first story for boys, Hollowdell Grange, appeared in 1867. It was followed by a succession of other novels for juveniles and adults. The Star-Gazers (1894), for example, was a three-volume "astronomical romance" for adults. Having become the editor of Cassell's Magazine in 1870, Fenn then purchased Once a Week and edited it until it closed in 1879. He also wrote for the theatre.
