The South African - known as the Flying Dentist - was a member of the first Leeds team to win rugby league’s Championship, in 1961.
A Springbok international, he switched codes to join Leeds in 1959 and scored 73 tries in 81 appearances, but moved to Hull for the 1961-62 season.
He touched down 42 times in 86 appearances for the Airlie Birds before returning to South Africa in 1964.
Phil Caplan, chairman of Leeds Rhinos’ heritage committee, said: “Notification came through this morning that Wilf has passed away in hospital in Israel after suffering a stroke.
“His contribution to Leeds’ first Championship win was absolutely massive and will never be forgotten.”
Rosenberg’s centre during his glory days at Leeds was Derek Hallas.
He said: “Wilf was such a nice guy and the best winger I played with.
“For a man of his size, he was one of the bravest players I have played with and he was a terrific finisher.”
