Courtney Ryley Cooper (1886–1940) was a versatile American author, circus performer, and publicist whose diverse career spanned several decades in the early twentieth century. Over the course of his literary career, Cooper was an incredibly prolific writer, publishing more than thirty books. His written work drew heavily from his unique personal experiences and professional background, allowing him to bridge the worlds of popular entertainment and investigative journalism.
A significant portion of Cooper's bibliography focused on the subject of crime. His deep understanding of criminal matters and law enforcement earned him high praise from prominent figures of his era. Notably, J. Edgar Hoover, the director of the Federal Bureau of Investigation, once described Cooper as the single best-informed man on the subject of crime in the United States. This reputation established Cooper as a key authority on the American criminal landscape during a period of intense public interest in the subject.
In addition to his crime writing, Cooper was widely recognized as an expert on the circus. His passion for the big top was not merely academic; he worked directly within the industry as both a performer and a publicist. At the time of his death in 1940, he was serving as the chief publicist for the world-famous Ringling Brothers, Barnum & Bailey Circus, cementing his legacy as a premier chronicler and promoter of American circus history.
