Leonard Barr (September 27, 1903 – November 22, 1980) was an old-style, one-liner standup American comic in the tradition of Henny Youngman.

Leonard Barr as Shady Tree in ‘Diamonds Are Forever.

He was the uncle of Dean Martin (being the brother of Martin’s mother Angela). Thanks to Martin, and TV talk shows, he achieved a significant amount of visibility and recognition in the twilight of his career.

He had a brief cameo in The Sting, appropriately as a burlesque comic. That is also the way his character is listed in the credits, as an anonymous comedian. However, in the wings of the stage just before the comic’s entrance, he has a brief conversation with Johnny Hooker (Robert Redford), who addresses him as “Leonard”.

He is perhaps best remembered internationally for his appearance in the 1971 James Bond film Diamonds Are Forever in which he played Shady Tree.
