Following a successful career as a professional wrestler, Hart founded a development and training company called Stampede Wrestling and also operated a training facility out of his mansion The Hart House. He is famous for his mentorship of numerous professional wrestlers, including many members of his own family.
He spent his early childhood in poverty: his family lived in a makeshift home on the western Canadian prairie. After his father was convicted of tax evasion, Hart and his mother and siblings were aided by the Salvation Army and were given a home in Edmonton, Alberta, where Hart began training as a wrestler at the local YMCA.
In early 2010, he became a posthumous inductee into the World Wrestling Entertainment, Inc. (WWE) Hall of Fame.
His more than five-decade marriage to Helen Smith resulted in twelve children, including famous wrestlers Bret and Owen Hart.
His grandson Teddy Hart had a successful career as a WWF wrestler.
