David Carroll Henry (1879-1931), aka 'Henry Leverage''Henry Leverage' was arguably the most prolific and successful pulp fiction writer of the immediate post-World War I era, yet you will find little about him online or in print - certainly very little that's true. 'Henry Leverage' was not born in London, England, but in WaKeeny, Trego County, Kansas. He was born in on October 9, 1879, not 1885, and baptised in Philadelphia in 1886. He never stepped foot in England and never defended London with the Royal Air Force in 1917-18. But he did spend time in Sing Sing Prison in Ossining, New York, and was forever the king of spinning a good yarn... mostly with the aid of a Corona 3 portable typewriter and a most lurid imagination.
