Yancy Derringer is an American Western series that ran on CBS from 1958 to 1959, with Jock Mahoney in the title role. The show was produced by Derringer Productions and filmed in Hollywood by Desilu Productions. Derringer Productions consisted of half interest for Warren Lewis and Don Sharpe as executive producers, and a quarter interest to Jock Mahoney for starring in the series, and a quarter interest to Richard Sale and Mary Loos, husband and wife, as creators. Desilu had just completed the 1956 series The Adventures of Jim Bowie which was also mostly set in New Orleans. The show's sponsor was Johnson Wax, now S. C. Johnson, and CLEAR floorwax was a regular sponsor. The Sales based the series on a 1938 short story that Richard Sale had written. In the 1930s, Sale was one of the highest paid pulp writers. Which story was never mentioned, but it was about a destitute aristocrat and troublemaker who returns to New Orleans three years after the Civil War. In the story, Derringer has no first name; "Yancy" was added for the TV series.
