A vocabulary of criminal slang : with some examples of common usages
by Louis E. Jackson
About the author
Louis E. Jackson was an American writer remembered for A vocabulary of criminal slang: with some examples of common usages, a reference work first published in Portland in 1914 or 1915. Project Gutenberg identifies him as Louis E. Jackson (1877–1922), and surviving editions show that the book was written with assistance from C. R. Hellyer of Portland's City Detective Department.
The book set out to explain the language of the criminal underworld for readers such as law officers, journalists, and other professionals. Rather than treating slang as a curiosity, it presented it as practical knowledge: a way to understand hidden speech, reduce secrecy, and make communication in criminal investigations easier to follow.
Very little biographical information about Jackson is easy to confirm from reliable online sources, which makes him a somewhat shadowy figure today. Still, his book has lasted because it preserves a slice of American speech that might otherwise have vanished, and it remains an interesting resource for readers drawn to crime history, language, and the social world behind old detective writing.
