Former heavyweight champ Jack Dempsey, the “Manassa Mauler,” the most famous athlete on earth during the 1920s, on What’s My Line?, 1965. During the interview segment, Dempsey suggests that the Ali-Liston fight was bogus.

In 1927, at the end of his run of dominance thanks to age and Gene Tunney, while he was training for a return to greatness which would never arrive, Dempsey suffered a personal tragedy when his brother, John, murdered his wife and committed suicide. An excerpt from a July 3, 1927 New York Times article:

“Schenectady–Apparently in a spell of temporary insanity due to a recurring attack of an illness to which he had been subject for several years, John Dempsey, brother of the former heavyweight champion, fatally shot his 21-year-old wife, Edna, in a rooming house here today. He turned the gun on himself, dying instantly.

The Dempseys had been estranged for about a year. They are survived by a two year-old son, Bruce.

Jack Dempsey was deeply affected when notified at his training camp at White Sulphur Springs, Saratoga Lake. He came at once to Schenectady and positively identified the bodies.

The boxer ordered his brother’s body to be sent tonight for burial to Salt Lake City, his former home, and Mrs. Dempsey’s body to be taken to Green Island.

It was announced that Jack Dempsey would cease his training activities for a few days because of the tragedy, but would not cancel his match with Sharkey, set for July 21 in New York City.”
