He next club was St Bernard's in 1937. He captained the Edinburgh side to the Scottish Cup semi-finals in his first season at the Gymnasium, where they eventually lost to fellow Second Division side East Fife in a second replay.
Dundee United
He became one of new Dundee United manager Bobby McKay's first signings during the close season of 1939 and again was made club captain but only four League matches of season 1939–40 were played before the competition was abandoned. Kerr was one of only three players who remained with United after the outbreak of war, and played as his team progressed to the final of the Emergency War Cup. He was, however, unlucky to sustain a shoulder injury in the semi-final which kept him out of the final against Rangers, at Hampden.
Rangers
Kerr spent two years with Rangers after the war before moving towards a coaching career.
It was in the field of football management where Kerr's true strengths began to emerge. His first post was as player/manager with the East of Scotland League club Peebles Rovers, followed by a spell at Berwick Rangers.
Alloa Athletic
Kerr was appointed manager of Alloa Athletic in 1955, a club where he had spent time as a player. He became known as having an eye for a good player, also having a theory that the bigger the club, the worse the talent-spotting. When at Alloa he assembled a partnership of inside forwards Dennis Gillespie and John White. Two years later Kerr sold White to Falkirk. Tottenham Hotspur a year later spent £20,000 to lure White to North London.
Dundee United
In 1959 United manager Andy McCall, resigned after leading the part-time club to third bottom place in Division Two. Jerry Kerr was the man given the task of reviving the club in April that year. Kerr's first policy upon joining United was his insistence that his players be full-time, a gamble that could have cost the club dearly. He also insisted that there had to be a properly constituted reserve side and an end to the previous policy of buying in over-the-hill First Division players. Ron Yeats' career took an upward turn from Kerr's appointment. Kerr regarded Yeats as so vital to the fortunes of the team he sought his release to play each Saturday from the military authorities while Yeats served his National Service. In Kerr's 1959–60 first full season in charge, St Johnstone finished as champions. United's challengers for the second promotion spot were Hamilton Academical and Queen of the South. Hamilton were beaten 5-1 at Tannadice with seven games to go before a crowd of over 11,000 putting Accies firmly in United's rear view. United went to Palmerston Park to play the Ivor Broadis inspired Queen of the South with three games to go. United returned home with a 4-4 draw to maintain their one-point advantage over QoS. Promotion was clinched with a last game of the season 1-0 home win against Berwick Rangers before a crowd of near 17,000. This brought First Division football to Tannadice for the first time since they had been relegated in 1932. In the following 1960–61 season United retained their top division place. Other players to flourish like defensive giant Yeats were the forward pair Gillespie and Jim Irvine scoring 21 and 23 goals respectively. United finished a creditable ninth. Kerr was imaginative and inspired with some of his signings. With Hal Stewart of Morton, he was the first to see the possibility of tapping Scandinavia for cultured players at an affordable price. And by 1964, Lennart Wing, Finn Døssing, Mogens Berg and Örjan Persson were Tannadice stalwarts. Kerr is also credited with another landmark moment in the club's history, as he led United into their first ever European tie in 1966. This produced a 4–1 aggregate victory over FC Barcelona in the Fairs Cup that included a 2–1 win at the Nou Camp. In November 1971 he assumed the post of general manager. Jim McLean took over as manager of football matters to build upon Kerr's successful base over the following seasons. Kerr then left the club, with the minimum of publicity, at the end of season 1972–73. Kerr is remembered for taking United from third from the bottom in Scottish League Football to a secure place in the top division. More than thirty years later the Club recognised the huge contribution Jerry had made when they renamed the south stand the Jerry Kerr Stand.
