Professional wrestling career
Early career
Started wrestling in Toronto for Maple Leaf Wrestling as the "Flying Frenchman' Jacques Dubois. He would start training Terrible Ted, an American black bear, stood 7"0 and weighed 600 lbs. Ted was declawed and detoothed, and travelled with a carnival in his early years, When the carnival went bankrupt in the early 1950s, McKigney adopted and trained him. On Boxing Day in 1958, before 8,250 fans, "Terrible" Ted defeated his mentor McKigney at Maple Leaf Gardens in Toronto. He wrestled three more matches for Maple Leaf Wrestling to start 1959, then headed to Stampede Wrestling in Calgary, working Stampede Wrestling's territory across Alberta and Saskatchewan. He also had a couple of matches for Tri-State Sports in Idaho. With Terrible Ted, McKigney eventually grew out his hair long and had a scruffy beard and wrestled under the Bearman and Wildman gimmicks.
Canada
McKigney was a big name in Canada mainly at Maple Leaf Wrestling in Toronto as the Canadian Wildman. He went to Stu Hart's Stampede Wrestling in Calgary in 1959 and used his name as Gene Dubois, Pierre Dubois and Dave Dubois. MicKigney often teamed with The Wolfman. On July 13, 1966, McKigney offered $3,000 to anyone who could pin Ted. The challenge was accepted and met by John Szigeti, who pinned Ted "for maybe 15 seconds" before McKigney pried him free. McKigney and promoter Howard Darvin refused to pay the prize, so Szigeti sued them in May 1968. He would sometimes wrestle in Japan even defeating Japanese legend Antonio Inoki by disqualification, the United States in Michigan and Ohio. McKigney would wrestle until his death.
In 1969, McKigney made his debut in the Northeast US for the World Wide Wrestling Federation as Jean Dubois or sometimes spelled Gene Dubois. He was a jobber mainly having matches against Ivan Koloff, Lou Albano, Waldo Von Erich, Chief Jay Strongbow, and The Wolfman. His biggest victory in WWWF was when he defeated Lou Albano. Dubois would have two titles shots against WWWF Champion Ivan Koloff. He would stay with the company until 1972.
Japan
In 1975 McKigney had a stint for New Japan Pro Wrestling where he feuded with Seiji Sakaguchi and Antonio Inoki. His biggest victory was win over Japanese legend Antonio Inoki by disqualification. Inoki got his revenge by defeating the Canadian Wildman.
Late career
By the late 1970s McKigney wrestled mainly in Toronto and Detroit's Big Time Wrestling into the 1980s.
Personal life
He trained his step-daughter, Rachel Dubois, who wrestled for a brief period in the 1970s. On July 2, 1978, in Aurora, Ontario, McKigney left the door open on the cage of his second bear, Smokey, while he answered the phone. Smokey entered McKigney's house and mauled his girlfriend, 30-year-old Lynn Orser, to death. As a result, both bears were taken away by the Ontario Humane Society. Smokey showed no signs of rabies as of July 5, but was under a 14-day quarantine. McKigney's only possible explanation was that bears sometimes act unpredictably during mating season. On July 4, 1988, in Newfoundland, McKigney was driving to a wrestling show with Adrian Adonis and twin brothers William "Mike Kelly" Arko and Victor "Pat Kelly" Arko. Driver William Arko swerved to avoid hitting a moose on the Trans-Canada Highway and crashed the van, injuring himself and killing his brother, Franke and McKigney. McKigney's son, 8-year-old Davey Jr., witnessed the accident from a following vehicle.
