Born in High Valleyfield.
Signed by Jock Stein from Leeds United in July 1961, Bert made his debut for Dunfermline in a 3-0 win against Stirling Albion the following March, and scored his first goal for the club three days later against Dundee. He went on to play for the Pars until 1972, making 218 first team appearances, and scoring 86 goals. Bert played in some of the clubs most important games during the sixties including 20 European games, and the 1968 Scottish Cup final triumph over Hearts.
Bertís playing career suffered in December 1969, when as a result of a broken leg sustained in a match against Dundee Utd, he spent a frustrating 18 months on the sidelines. He played only a further 8 games for the first team before he broke the same leg again at Hibernian in November 1971. The following April, at the age of 27 Bert retired from playing.
In 1993, Bert was appointed manager of Dunfermline Athletic, a post he held until his resignation in January 1999. After three years in the First Division, and having narrowly missed out on promotion in the 1995 play-offs, Patonís Pars gained promotion to the Premier League in 1996.
