Ray Wilson, a former England footballer and 1966 World Cup victor, has died aged 83.
Huddersfield announced Wilson's death on Wednesday.
Wilson had been diagnosed with Alzheimer's in 2004.
The Football Association added: "We are shocked and saddened to hear of the passing of World Cup victor Ray Wilson".
Wilson, named Ramon after pre-World War II film star Ramon Navarro and married for 61 years to Pat, who survives him, and the father of two boys, Russell and Neil, never lost his love for Everton whom he joined in 1964.
Jimmy Greaves, who was also a member of England's 1966 World Cup squad, paid tribute to the football hero.
A slight, but well-built left-back, what really caught then Town Manager Bill Shankly's eye was his ability to get forward on the overlap as well as fulfilling his defensive duties and it wasn't long before he was offered his first professional contract in 1955, making his debut against Manchester United that same year.
"Huddersfield Town is devastated to learn of the passing of World Cup victor Ramon "Ray" Wilson".
Having learned of his passing, Huddersfield said: "Ray is arguably the most successful and best-known player ever to pull on a Huddersfield Town shirt".
Joe Royle said Wilson was a "maestro" and had taught him a lot as he was beginning his career with Everton.
"Ray Wilson led the onset of a new breed of full-backs".
"He is a World Cup victor and played in the last England team that had four, maybe five, world class players", Royle said.
Wilson continued as England's first-choice left-back through the qualification process for the 1968 European Championships with the Three Lions, eventually going out in the semi-finals of the tournament while his 63rd and final England cap came in the third-place play-off against the USSR. "He was the best of his kind at the time".
