Robert Francis Jeaudoin was an American professional wrestler and civil engineer, also known by the ring name of "Hangman" Bobby Jaggers. Most of his renown as a wrestler came from his appearances in various National Wrestling Alliance-affiliated promotions. In particular, he found his greatest success in Championship Wrestling from Florida and Pacific Northwest Wrestling, the latter near his hometown of Vancouver, Washington. His wrestling gimmick was of a cowboy from Kansas, where he spent the later years of his life. Debuting under the name "Bobby Mayne" (after his favorite wrestler Lonnie Mayne) in 1972 in the Pacific Northwest against Al Madril, Bobby Jaggers learned his craft. Soon after debuting, he moved to Memphis, where he teamed with Charlie Fulton and was managed by Sir Steve Clements. In 1973, he moved to Kansas City, where he caught the eye of Dory Funk, Jr., who wanted him in his Amarillo territory, in which he did split his time between the two territories. In 1975, after a brief stint in San Francisco, he went to Louisiana to work for Bill Watts, where he formed a team with Jerry Brown. He later moved up to Canada in Vancouver, working for Al Tomko and All-Star Wrestling, but didn't last long, as he left after a falling-out with Gene Kiniski. He then moved down to Atlanta for NWA Georgia Championship Wrestling, where he teamed up with Sterling Golden, who would go on to become one of the most iconic wrestlers in the world, Hulk Hogan. He would also wrestle in Knoxville for while, before moving down to Florida.

It was in Florida, where Bobby Jaggers found his niche. He feuded with Dusty Rhodes all over the territory. During that time, he would wrestle on and off for World Wrestling Council in Puerto Rico, wrestle eighteen tours of Japan, and some shows in South Africa.

In 1984, he went to Portland for Don Owen and Pacific Northwest Wrestling. While there, he won four Heavyweight titles and two Tag Team titles, with one partner each, before leaving for the Mid-Atlantic area ran by Jim Crockett Promotions. While there, he formed his well-known tag team The Kansas Jayhawks with Dutch Mantel. In 1986, they lost to Ivan Koloff and Krusher Khrushchev in a tournament final to determine the inaugural NWA United States Tag Team Champions. Jaggers would remain in JCP until 1988.

By 1988, Bobby Jaggers wrestled actively in Puerto Rico for WWC. But on July 16, 1988, one incident changed his life forever. After a show, Bruiser Brody was murdered in the shower in the locker room. Jaggers was in the heel locker room when Brody was in the face locker room. The murder made him slowly phase his career out, before finally retiring in 1991.

In fall of 1989, Jaggers made two appearances in the WWE losing to Jim "The Anvil" Neidhart and a tag team against The Rockers.

In 1989 Bobby Jaggers teamed with Black Bart and were called the Southern Force in the FCW/PWF and held the tag team titles one time after beating the Nasty Boys in St Petersburg Fl. Then Jaggers and Black Bart lost the title to Dustin Rhodes and Mike Graham in Tampa Bay Fl. The FCW/PWF was being booked and run by Dusty Rhodes, until Dusty left for WWE. FCW/PWF closed down in 1991.
