the ladder match could have been invented by either dan kroffat of the stampede wrestling organization out of calgary, alberta, canada or british wrestler kendo nagasaki. in september 1972, stampede wrestling held the first ever ladder match between dan kroffat and tor kamata, where the object to be grabbed was a wad of money. in 1987, kendo nagasaki competed in a "disco challenge" ladder match against clive myers on the popular "world of sport". the aim of this match was to retrieve a gold coloured disco record suspended above the ring.
