The defender, who played 283 games for Town and scored six goals during a 12-year spell, was signed by Bill Shankly and quickly became the club's established first choice left-back.
He remains Town's most-capped England player - picking up 30 before a move to Everton in 1964 and he eventually ended his international career with 63 caps.
Wilson went on to play for Oldham Athletic and then became caretaker manager at Bradford City before his footballing career came to an end in 1971.
After football he set up an undertakers business in Outlane and was a regular face at Town home games, making the short from his house in picturesque Slaithwaite with one of his two sons, Russell, 58 or Neil, 56.
