The Fascinating History of Gumshoe and Gumdigger Slang Terms

"Gumshoe" and "gumdigger" are slang terms that were historically used to refer to private investigators, particularly those who worked in the United States during the mid-20th century. The term "gumshoe" was popularized in the 1940s and 1950s, and it is derived from the word "gum," which was slang for a private investigator's shoe soles, which were often made of rubber to allow them to sneak up on suspects without being heard.

The term "gumdigger" is a variation of "gumshoe" that is thought to have originated in the 1930s. It is similar in meaning to "gumshoe," but it is often used to refer specifically to a private investigator who is hired to dig up dirt or information on someone.

Both "gumshoe" and "gumdigger" are now largely obsolete, and they have been replaced by more modern terms like "private investigator" or "PI." However, they remain an interesting piece of history and trivia for those interested in the subject.
