Youngest child of the legendary Hart wrestling family of Calgary, Alberta, Canada, which also produced Bret "Hitman" Hart one of the WWE's most celebrated champions.
Owen wrestled and tolied in mid-card matches for years before finally gaining main event status in the mid-to late 90's.
In possibly the worst decision he ever made, Owen followed the direction of his boss, Vince McMahon to be lowered to the ring during his entrance on May 23, 1999 in the Kemper Arena in Kansas City.
And in the worst tradegy ever in wrestling history Hart fell 90 feet from the ceiling to the ring below, snapping his neck on a turnbuckle.
Whether Hart prematurely released the harness holding him or it malfunctioned has never been revealed.
Owen Hart died while working for the WWF on May 23, 19999.
