Born Glasgow, Bobby was a Scotland international after beginning his career with Celtic and soon became renowned as one of Scotland's greatest inside-forwards.
At Celtic, he struck 115 goals in 320 appearances, helping his side to a League Title and Scottish League Cup and also becoming one of few players to have scored a hat-trick of penalties in a single match, when he did so against Aberdeen in September 1953.
After a remarkable playing career in the game, which also included spells at the likes of Everton and Leeds, Bobby arrived at Oakwell in 1980 to become the Reds' Youth Team Coach.
Following the departure of Norman Hunter, Bobby took over as First-Team Manager in February 1984 - which was a testing time in the town, considering the Miner's Strike and its consequential effect on the Oakwell attendances.
The thoughts and prayers of everyone at Barnsley Football Club are with Bobby's family at this difficult time.
