Question: Which professional wrestler promoted by Toots Mondt was born in 1939?
Context: Randal Barry Orton (born May 28, 1958), better known as Barry Orton, is an American actor, musician, and former professional wrestler.  He is the son of retired professional wrestler Bob Orton, brother of professional wrestler Bob Orton Jr., and uncle of professional wrestler Randy Orton. Jack Taylor (born 1887) was a Canadian successful amateur and professional wrestler.  Considered to be Canada's first great wrestling superstar in his time he was the childhood idol of wrestling icon Stu Hart and trained Toots Mondt. James Ervin Mondt (January 18, 1894 – June 11, 1976) was an American professional wrestler and promoter who revolutionized the wrestling industry in the early to mid-1920s and co-promoted the World Wide Wrestling Federation.  Some of the stars Mondt helped create from the 1920s through the 1960s included Wayne Munn, Jim Londos, Antonino Rocca, Bruno Sammartino, Stu Hart and Cowboy Bill Watts. Robert Keith Orton Jr. (born November 10, 1950), better known by the ring name "Cowboy" Bob Orton, is an American professional wrestler.  He is the son of professional wrestler Bob Orton Sr., the brother of professional wrestler Barry Orton, and the father of professional wrestler Randy Orton.  He is best known for his time in the WWF (World Wrestling Federation, now WWE).  He has also wrestled for several promotions in the United States, Japan, and other countries. The history of WWE dates back to the early 1950s when it was founded by Jess McMahon and Toots Mondt in 1952 as Capitol Wrestling Corporation (CWC).  It underwent numerous name changes throughout the years, from World Wide Wrestling Federation (WWWF) to World Wrestling Federation (WWF) to World Wrestling Entertainment (WWE) in 2002. Capitol Wrestling Corporation Ltd. was an American professional wrestling promotion and the sanctioning body for the World Wide Wrestling Federation (WWWF) and later World Wrestling Federation (WWF).  Founded by Jess McMahon and Toots Mondt in 1953, Capitol Wrestling Corporation is the precursor to today's WWE, run by Jess' grandson, Vincent Kennedy McMahon. Wilhelm Baumann (September 4, 1884 – September 15, 1972), better known as Billy Sandow, was an American professional wrestler and promoter.  He is best remembered as the manager of professional wrestler Ed "Strangler" Lewis and a subsequent member of the famed Gold Dust Trio promotion that changed the face of the industry during the 1920s (along with Lewis and Joseph "Toots" Mondt).  He may have taken his ring name from Eugen Sandow, a professional wrestler and strongman in the late 19th century; in turn, former WWE wrestler Damien Sandow would adopt his own ring name in honor of Sandow almost a century later.  Sandow also served as manager for such wrestling champions as Billy Jenkins, Marin Plestina, Jumping Joe Savoldi and Everett Marshall, and also used the ring name The Zebra Kid in 1951.  He was a charter inductee of the Wrestling Observer Newsletter Hall of Fame in 1996. Roderick James "Jess" McMahon Sr. (May 26, 1882 – November 22, 1954) was an American professional wrestling and professional boxing promoter, and the patriarch of the McMahon family.  He founded the Capitol Wrestling Corporation with Toots Mondt in 1952.  McMahon's son, Vince Sr., later took over and founded the World Wide Wrestling Federation (WWWF) (today known as WWE). William F. Watts Jr. (born May 5, 1939) is an American former professional wrestler, promoter, and WWE Hall of Fame Inductee (2009).  Watts was famous under his "Cowboy" gimmick in his wrestling career, and then as a tough, no-nonsense promoter in the Mid-South United States, which grew to become the Universal Wrestling Federation (UWF). The Gold Dust Trio was a group of promoters who controlled the world of professional wrestling during the 1920s while also making several fundamental changes to the industry's business model and operations that would ultimately change the direction of the sport towards a more pseudo-competitive exhibition.  The Trio was composed of the era's dominant World Heavyweight Champion Ed "Strangler" Lewis and his manager Billy Sandow, as well as fellow wrestler and creative visionary Joseph "Toots" Mondt.
